3 Thomas Georg Miinster. Minnetale pl Norsk Entomologisk Forening's Brsmete 5. april 1938 av konservator L. Reinhardt Natvig. Niir vi idag er samlet ti1 brsmete i Norsk Entomologisk Forening, vil vi ferst minnes bergmester Thomas Miinster, v5r forenings mangeirige formann og eneste aeresmedlem, som avgikk ved deden 10. mars, fb dager efter at han var fylt 83 Ar. Minsters navn er pb det noieste knyttet ti1 denne forenings historie, og uten forkleinelse for andre, kan vi fastslii at han var dens centrale skikkelse og drivende kraft. Da foreningen hlev stiftet i 1904 var Munster en av stifterne, og efter all sannsynlighet er det ham som har tatt initiativet ti1 b samle de norske entomologer i en egen forening. Det fremgbr iallfall tydelig av viir protokoll at mens motene var bade f% og med lange mellemrum i de forste br, blev det annen fart i foreningens liv da Miinster kom ti1 Oslo og personlig kunde ta sig av saken. Han samlet entomologene ti1 regelmessige mclter, han ledet en rekke ekskursjoner og han var alltid i forste rekke n%r det gjaldt foreningens tarv. I Aret 1921 gjorde Miinster en ny innsats for norsk entomologi, idet han da startet ~Norsk Entomologisk Tidsskrift*, hvis redaksjon og ledelse han selv patok sig. De norske entomologer har alltid vaert fii i antall og dertil spredt over hele landet, sb det var et viigsomt foretagende % g% i gang med et eget tidsskrift, og det manglet da heller ikke pa advarende roster. At tidsskriftet blev fort lykkelig igjennem de fclrste vanskelige fir, skyldes Miinsters pbgangsmot og hans evne ti1 ii utnytte sine vidstrakte forbindelser ti1 finansiering av publikasjonen. 4 - Norsk Entomologisk Tidsskr

4 50 L. Reinhardt Natuig Nu er allerede V. bind pabegynt av vart tidsskrift, og nir vi ser tilbake pa det som er kommet, sa fremgar det tydelig at Miinster ikke bare var redakter, men ogsh en meget flittig bidragsyder. BAde systematiske oversikter over bestemte grupper og faunistiske bidrag fra ham finnes i nesten alle hefter som er utkommet. Han hadde et skarpt eie for morfologiske karakterer, og det foreligger en rekke nybeskrivelser fra hans hand. I 1924 utgav han, sammen rned prof. Knut Dahl og konservator Johs. Lid, et arbeide som hadde ti1 hensikt i gi en geografisk inndeling av vart, land rned henblikk pa de topografiske og ekologiske forhold. Dette arbeide:.a division of Norway into biogeographical sectional areas. la han selv ti1 grunn for sin store koleopterkatalog, et systematisk-faunistisk arbeide i manuskriptform, som antagelig scaker sin like innen Skandinavien. Manuskriptet er pi 12 store bind, og her har han, for samtlige kjente Coleoptera, samlet alle funn og anmerket hvad han personlig har kontrollert av andres bestemmelser. Miinster herte ti1 den gamle garde av de virkelig.store. samlere, og han hadde selv en privatsamling fra hele det palaearktiske faunaomrade pa ca arter i over eksemplarer. Han stod i personlig forbindelse rned Ganglbauer, Schuster, Reitter og andre kjente europeiske forskere, og som et uttrykk for den anseelse han nod kan nevnes at en rekke nye bille-arter blev opkalt efter ham. Samlingen overdrog han i 1918 ti1 Universitetets zoologiske museum og Bergens museum sammen rned sitt bibliotek, idet han av Stortinget blev bevilget et tillegg ti1 sin pensjon.ti1 fortsatt videnskapelig virksomhet~. Miinster var en rikt utrustet mann hvis evner blev lagt beslag pa innen de forskjelligste kretser. I sitt egentlige fag innehadde han en rekke viktige stillinger; han var amanuensis ved Universitetets metallurgiske laboratorium , aspirant ved Kongsberg Selvverk , assistent ved Norges Geologiske Undersekelse , myntguardein , mynt- mester , distriktsbergmester i Finmarkens distrikt og i 0stlandske distrikt I 1918 tok han avskjed rned pensjon for helt H vie sig ti1 entomologien. I stillings medfer foretok han en rekke utenlandsreiser. Han var ogsi en ivrig politiker og deltok bade i styret av kommune og stat. I Arene og var han medlem av Kongsberg formannskap, var ordferer 1888, 1892, og , stortingsrepresentant i , odelstingssekretaer , stortingssekretzr Som medlem av stortingets fredsforening mette han ved de interparla- mentariske konferanser i Haag i 1894 og i Budapest i Han var formann i Bergingenierforeningen , medlem av

5 Thomas Georg Miinster 5 1 N. I. F.'s representantskap og styremedlem i flere industrielle foretagender. Han var ogsa medlem av Det Norske Videnskaps- Akademi i Oslo, zresmedlem av Entomologiska Fiireningen i Stockholm, Entomologiska Fiireningen i Helsingfors og av Norsk En tomologisk Forening. Billedet vilde ikke bli fullstendig uten A nevne at Miinster ogsd var en ivrig filatelist og stor blomsterelsker. Hans kaktussamling, som han med kyndighet og kjzrlighet pleiet ti1 de siste fir, var ikke sa lite av en severdighet. Vi takker for alt han har ydet ti1 beste for norsk entomologi, og vi haper det ma lykkes A fare videre det grunnleggende arbeide han har utfert for A bedre kjennskapen ti1 Norges koleopterfauna.

9 The Norwegian Mayflies (Ephemerop fera). By Reidar Brekke, Trondheim. The investigation of the insect group Ephemeroptera has in recent time been the source of great interest. Investigators in our neighbouring countries Denmark, Finland and Sweden have, as also investigators in other European countries, published accounts of the ephemeridae of their countries. Esben Petersen, Copenhagen, gave an account of Denmark's ephemeridae in 1910 (Bibl. nr. 30). J. E. Aaro, Helsingfors, wrote hi* last synopsis over Rnland's ephemeridae in 1928 (nr. I), and L. Tiensuu has since then continued investigation of this group in Finland (nr ). Simon Bengtsson, <Lurid, has from 1903 until 1931 published a number of papers on the subject (nr. 2-12). As regards Norway no comprehensive account of ephemeridae including the whole country has been published since the paper of the late state entomologist W. M. Scheyen in 1887 (nr. 37). The present paper therefore is an attempt to give a revisal of the old material as far as it is preserved in the museum collections and thus can be controlled, and further to give an account of known Norwegian mayflies up to this date. I have inspected the following Norwegian collections: 1. Zoological museum of the university, Oslo (Esmark, Siebke, W. M. Scheyen, Embr. Strand.leg. - Eaton, W. M. Scheyen det.) 2. Tromse museum, Tromse (Zetterstedt. Sparre-Schneider, Soot- Ryen, leg. - Esben Petersen, Bengtsson det.) Furthermore my list includes material collected in more recent time and placed at my disposal for determination. Professor Dr. Knut Dahl (the leader of the "Experimental Research Work on Freshwater Fisheries" and his assistant cand. real. Sven Semme have sent me the material brought together by the institute (Knut Dahl, 0. Olstad, J. D. Semme, Sven Semme leg.) Konservator L. R. Natvig has sent me the material (chiefly larvae) collected by him in recent years in southeastern Norway including a few specimens from the museum magazines (Siebke, 0. Mathisen leg.). All this material is now brought together in one collection with my deter.minations and is deposited at the Zoological Museum at Oslo.

10 5 6 Reidar Brekke Dr. Hartvig Huitfeldt-Kaas, Oslo, has sent me material collected by him in various parts of the country through several years. Mr. Fritz Jensen, Stavanger, has sent me some dried imagines chiefly from the neighbourhood of Stavanger. The Oslo Angling Association has sent me material collected by the members all over the country. Finally the list includes my own material collected in the recent 5 years in various parts of the country, chiefly in Trendelag. This collection is deposited at the Museum in Trondheim. Norwegian ephemeridae described by older authors. The oldest paper found giving details on Norwegian mayflies was published by pastor H. STRQM in 1783 (nr. 41). In his "Norske Insecters Beskrivelsen he gave an account of the follow-, ing four species: 1. Ephemera leucopthalma. 2. Ephemera caudata. 3. Ephemera bioculata. 4. Ephemera cilia fa. Later investigators have been of different opinion as to the identification of the species described by Strem, the scantiness in his description giving no certainty as to the species. The Swedish entomologist H. D. J. Wallengren in 1882 came to the conclusion that Strem's description Eoncerned the following species: 1. Baetis sulphurea MULL. syn. Heptagenia elegans ETN. 2. Centroptilum luteolum MULL. 3. Ephemera bioculata LIN. or Cloe bioculata LIN. 4. Cloe pumila BURM. syn. Eph. striata LIN. Dr. Simon Bengtsson in came to the conclusion that Strem's four mayflies must be: 1. Heptagenia sulphurea MULL. 2. Centroptilum luteolum MULL. 3. Baetis tenax ETN. 4. Baetis Wallengreni BGTN. or Baetis pumilus BURM. The presence of these 5 mayflies in Norway has later been awertained. Pastor SOMMERFELDT mentions in his "Description of Saltdalen" ("Kgl. Norske Videnskabsselskabs Skrifter av 1827") - (no. 39) one species of mayflies, viz.: Caenis brevicauda FABR.

11 The Norwegian Mayflies 57 W. M. Scheyen has later expressed his doubt as regards this determination, probably from the fact that Caenis at Scheyen's time was only known from the southern part of Norway. As I however have found Caenis horaria at the height of 300 m above sea level in Trendelag it may be possible that species of Caenis may also be found in Saltdalen. E. SIEBKE mentions in the publication of his researches in 1870 and 1873 (no. 38) the following species of mayflies: 1. Ephemera vulgata LIN. found at Krydsherred and Grundset. 2. Ephemera venosa found at Henefos, Nss and Austad river. Although all the specimens are not preserved the discovery of Ephemera vulgata may be presumed to be correct as this easily known species has seldom been the object df mistake. Ephemera venosa or Ecdyonurus venosus has not later been found in Norway, and it is not represented in the existing collections. As this species can easily be confused with Ecdyonufus fusco-griseus there remains some doubt about its existence in Norway. In Zetterstedt's collection Bengtsson found two specimens labelled Ephemera venosa FABR. from Norway one female from Bosekop, Pinnmark, and "Var. bn represented by one 6 and one? from Kautokeino, Finnmark. The first mentioned was Heptagenia dalecarlica BGTN. subimag. 9 and the two other specimens were Heptagenia dalecarlica BGTN. imag. 6 and 0. In mtallengren's collection Bengtsson found one specimen labelled Heptagenia venosa FABR. from Aaset in Norway. This was a Heptagenia dalecarlica B~TN. The Swedish entomologists Zetterstedt in 1840 and H. J. D. Wallengren in 1882 published lists over ephemeridae discovered in Scandinavia including Norwegian mayflies. These publications as well as Zetterstedt's and Wallengren's collections have been revised by Bengtsson in his "Analysis of the Scandinavian species of Ephemeridae described by older authorsn 1912 (nr. 8). In 1871 Eaton (nr. 13) published an account of a new discovery in Norway of a species which he called Rhithrogena borealis, habitat said to be Finnmark county between Kautokeino and Karesuando and probably found by the English entomologist T. A. Chapman (Walker MS. in Dale mus.). Hope Professor G. D. Hale Carpenter, Oxford, has kindly sent me this specimen for examination. It is a dried specimen without legs. The neuration of the wings and the genitalia show that it is a Metretopus norwegicus imag. 6 Etn (nr. 15). The correct name for this species should then be Metretopus borealis with: Heptagenia borealis Etn. 1871, Rhithrogena borealis Etn. 1885, Metretopus norwegicus Etn as synonyms.

Schoyen published the first list of Norwegian ephemeridae in his "Classification over the hitherto known Neuroptera Plannipennia and Pseudoneuroptera" (nr. 37). Schoyen in this, paper refers to Sommerfeldt, Siebke, Zetterstedt and Wallengren and his list contains the following 15 species: 1. Ephemera uulgata LIN. without doubt found over the whole of Norway. 2. Leptophlebia marginata LIN. Oslo and Dovre. 3. Leptophlebia cincta RETZ. Oslo, Dovre, Finnmark Caenis halterata FABR. Oslo. 5. Baetis bioculatus LIN. over the whole country. 6. Baetis vernus CURTIS. Hammerfest, Alta. 7. Baetis muticus LIN. Sunnmore (H. Strom: Ephemera ciliata). 8. Baetis vitreatus ZETT. Alta, Sorvaranger. 9. Centroptilum luteolum MULL. Sunnmore, Finnmark. 10. Cloeon dipterum LIN. Oslo, Bodo. 11. Heptagenia borealis ETN. Finnmark. 12. Heptagenia semicolorata CURT. Finnmark. 13. Heptagenia sulphurea MOLL. Sunnmore, Elverum, Qsterdalen. 14. Heptagenia jluminum PICT. Gudbrandsdalen, Dovre. 15. Heptagenia venosa FABR. Qstlandet, Dovre. The material preserved at the Zoological Museum, Oslo, arranged by W. M. Schoyen, consists of dried specimens, but unfortunately some of them are now in such a fragmentary condition that I have found it impossible to give a distinct identification of all specimens.

13 The Norwegian Mayflies 59 The collection at present consists of: 1. Ephemera uulgata. This species is represented in the collection by 12 imag. 6, 1 imag.? and 1 subimag. 6. It is this species. 2. Leptophlebia marginata. This species is represented by 4 imag. 6. It is this species. 3. Leptophlebia cincta. (Paraleptophlebia cincta). This species is represented by 4 imag. 6 and 1 imag.,the latter labelled in Eaton's handwriting. The 4 imag. 6 are Paraleptophlebia cincta. Tbe imag. is Ameletus inopinatus Etn. imag.? 4. Caenis halterata. This species is represented by 3 subimag. They are in a fragmentary condition and undefinable as to species. They are most probably Caenis horaria syn. Caenis halterata. 5. Baetis bioculatus. This species is represented by 3 imag. 6 and 5 imag imag. 6 are Baetis rhodani and 1 imag. 6 is Cloeon praetextum BOTN. The five imag.? are undefinable as to species, but Baefis rhodani is most probable. 6. Baetis vernus is not represented in the collection. 7. Baetis muticus is not represented in the collection. 8. Baetis vitreatus is not represented in the collection. 9. Cenfroptilum luteolum is represented by a very defective specimen. It is a Baetis sp. 10. Cloeon dipterum.

This species is represented by 1 very defective specimen. It is a Cloeon sp. but species undefinable. Furthermore the following specimens were found undetermined in the same case: Paraleptophlebia cincta 1 subimag. d. Leptophlebia vespertina 1. imag 9, 1 subimag. d and 3 subimag 9. Baetis sp. 3 specimens undefinable as to species. Chitonophora sp. 1 imag d" and 1 imag. 0. For the species not found in the collection Schayen has probably cited details from Zetterstedt's and Wallengren's publications. Bengtson's revisal of these two investigators collections has however shown that their determinations are not in accordance with modern systems of classification. New lists can therefore not be based on their publications. The same view will then be required as regards Schoyen's list and this list must be restricted to the species in the collection which are in such a state that a definite determination can be made. According to Eaton's publication in 1901 (nr. 15) the Norwegian entomologist Embrik Strand has sent him 700 specimens of ephemeridae collected in Norway for determination. Eaton's list includes the following species: 1. Leptophlebia marginata 2. Leptophlebia Meyerii 3. Leptophlebia Strandii (nov. spec.) 4. Baetis vernus 5. Baetis rhodani 6.' Chirotonetes sp. 7. Ameletus inopinatus 8. Siphlurus lacustris? 9. Siphlurus Linnaeanus 10. Siphlurus sp. 11. Metretopus norwegicus (nov. spec.) 12.' Rhithrogena sp. 13. Heptagenia sulphurea 14. E'cdyurus sp. Unfortunately it has not been possible to find this collection for examination. The genera Chirotonetes (Isonychia) and Rhithrogena are not represented in other Norwegian collections and they are not represented in Sweden.

15 The Norwegian Mayflies 6 1 As will be seen the list includes 2 species new to science, viz.: Paraleptophlebia Strandii and Metretopus norwegicus. The author also mentions that species of Ephemerella and Centroptilum are found in Norway. I July 1902 mr. and mrs. Eaton were travelling in Norway, and in the following year Robert Mc. Lachlan published the result of mr. Eaton's researches (nr. 25). This list includes the following species which were not earlier published as Norwegian ephemeridae by Eaton: 1. Ephemera vulgafa 2. Ephemerella sp. (later identified as Chitonophora Aurivillii BGTN.) 3. Baetis pumilus 4. Centroptilum luteolum 5. Siphlurus aestivalis (nov. spec.) 6. Heptagenia caerulans? In the magazines at Oslo Museum was stored a collection consisting of dried specimens labelled "Ephemeridae determ. Eaton 1902 leg. Embrik Strand". The collection has the following contents: 1. Leptophlebia Meyerii 9 specimens Tistedal. It is this species (Leptpphlebia vespertina LIN.). 2. Centropfilum sp. 6 specimens Nordreisen. They are not Centroptilum but Acenfrella lapponica BGTN. 3. Baetis sp. 1 specimen Kristiania May subim. It is Baetis but species not defineable. 4. Baefis rhodani 21 specimens whereof 19 specimens Nordreisen and 2 specimens Suldal. It is this species. 5. Ameletus inopinatus 2 specimens Nordreisen. It is this species. 6. Siphlurus sp. 2 specimens Nordreisen. It is Siphlonurus Zetterstedti BGTN. 7. Ecdyurus sp. 4 specimens Tistedal. It is Ecdyonurus sp. but species not defineable (Ecd. fuscogriseus most probable). The collection of ephemeridae in Tromse Museum (Zetterstedt - Sparre-Schneider leg.) was examined by the Danish entomologist Esben Petersen in 1902 and later collections of 1908 and 1909 leg. Sparre-Schneider were examined by him in Esben Petersen has published the result of his revision in Tromse Museums Aarshefter 1908 (no. 31) and 1910 (no. 32). Unfortunately the author ako includes in his lists details previously published by Zetterstedt, Wallengren and Scheyen.

16 62 Reidar Brekke In 1929 the collections in Tromse Museum were greatly' enriched by material collected by T. Soot-Ryen and examined by dr. Simon Bengtsson. Bengtsson published the result of his examination in Tromsp, Museums Aarshefte 1930 (no. 11). The collections contained 2 species new to science viz.: Paraleptophlebia tumida and Metretopus alter, and the number of known mayflies of northern Norway was brought up to 22 species. According to my opinion the publications of Eaton and Bengtsson must be the base for further investigations on the Norwegian mayflies. I consider my list as provisional and only as a basis for further investigations of this insect group in Norway, and hope that continued researches will bring new species to those already known. Of genera which in comparison with our neighbouring countries' mayflies may be counted on to be better represented in Norway I will mention Baetis, Caenis and Ephemera. In conclusion I have given a table over Norwegian mayflies showing which of them are also found in other Scandinavian countries. I want to express my gratitude to dr. Simon Bengtsson for his kind revisal of doubtful determinations (Chitonophora sp. and Baetis subalpinus?) and for his suggestions as to literature. I thank konservator L. R. Natvig, cand. real. Sven Ssmme and konservator Soot-Ryen for placing at my disposal the museum collections, and I thank for the confidence shown me by all who have sent me material for determination.
