﻿50 THE ENTOMOLOGIST. 



1. Plecoptera. 



Perla cephalotes. Female, Gabas. 



Arcynopteryx dovrensis. Two males, one female, Gabas. 



Ghloroperla grammatica. Gabas and Gavarnie. 



Nemoura variegata. Gabas. 



Nemoura (sp. ?). One male, two females, Gabas, belonging to the 



marginata group and somewhere near obtusa, but the single 



male is in poor condition. 



2. Ephemeroptera. 



One male sub-imago, apparently of the genus Bhitlirogena, with- 

 out any dark longitudinal, submedian, femoral streaks. The 

 Eev. A. E. Eaton cannot say definitely whether or not it is 

 Bh. semicolorata. Gavarnie. 



3. Odonata (= Paraneuroptera). 



SymiJetrum flaveoluvi. One male of mature colouring, four males 

 teneral, one female teneral, one nymph-skin with a female 

 recently emerged from it, another nymph-skin of the same 

 species but without the imago. All from Gavarnie. Dr. 

 Chapman says that the ponds producing S. flaveoium were 

 above 4430 ft. in altitude (say 5000 ft.) : a " hatful " (size not 

 mentioned) of nymphs, nymph-skins, and teneral imagines 

 might have been obtained there. Mature imagines had 

 usually left the neighbourhood and what efi'orts he made to 

 catch them were very unsuccessful. 



Cordulegaster aymulatus. One female, Gabas ; the left hind wing 

 deformed near the tip. 



Calopteryx virgo. One male, Gabas; wings with teneral colouring.

 black spots.
