GREN^ says: »Eaton har sammanfört Zetterstedts art med 

 Lepiophlebia cincta, dit den alls icke kan höra». He con- 

 sidered it as a Baetis Leach. Wallengren probably has 

 based his opinion upon Zetterstedt's statement »cauda 

 biseta». — Both the specimens in the collection (1 J" im., 

 1 § im.) show three setse, though in J" one is löst and in ^ 

 all three are broken, and they both belong to Euphyurus 

 vespertinus (Lin). {Eupliyur. alhitarsis Bgtn). 



9. Eph. hioculaia (1. c. pag. 1046. N:o 9). — Has by Zet- 

 TERSTEDT and all låter authors been regarded as synonymous 

 with LiNNÉ's species with the same name. Is represented 

 in the collection by five specimens, all collected at Stensele 

 the 3 July. Of the three male specimens two belong to Cen- 

 troptiliim diaphanum (Mull.) [luteolum auct.), im. J", and the 

 third is a Baetis, probably Baetis WaUe7igreni BGTi^i-. Of the 

 two other specimens, which are marked as ^, one, which is 

 very defective, is probably Centropiihim diaphanum (Mull.), 

 subim. J", the other is imago 5 of the same species. 



10. Eph. cidiciformis (1. c. pag. 1046. N:o 10). — All the 

 three specimens in the collection are subimagines $. Two 

 of them, both labelled »Grönland (Westermann)», belong to 

 Baetis tenax Eat., and the third, which is defective, seems 

 to be Cloeon simile Eaton.

 med Anmerkninger. K. Dansk. Vid. Selskabs Skrift. Ny 

 Samhng. Anden Deel. Kjobenhavn 1783. p. 90. N:o 131) is 

 probably Heptagenia sulphurea (Mull.), imago J*, as it has 

 also been regarded by Wallengren^ and others. He says, 

 however, that the »Rumpehaarene» are mereiy »hvide». 



2. Eph. caudata (1. c. pag. 91. N:o 132). — The charac-
