18 . NEUROPTERA. 



Female similar to the male, but the anterior wings with 

 very little colouring, the smoky tint being almost 

 entirely wanting; the apex of the marginal field is 

 slightly tinged with brown, the large oval whitish 

 egg-valve extends beyond the anus, and is cleft nearly 

 to its base. 

 Length of the body ^ 4f , 2 5 lines ; expansion of the 



wings $ 10^, $ 11| ; setas ^- 11 ; 2 6J lines. 

 Sub-imago. The colouring is black, with a dull grey 

 tint, only the four posterior legs and the anal forceps 

 are pale brown ; wings unicolorous, grey, the veins 

 margined, and hence appearing darker; the marginal 

 field of the anterior wings, especially towards the 

 apex, is darker; the posterior wings only a little 

 paler. 

 Habitat England. 

 Stephens' descriptions are made from female specimens of 

 unknown locality, my description from Prussian specimens 

 which I have compared with the types, and from an English 

 sub-imago. 



Of this species, which is so very common in the north of 

 Europe, one very rarely finds a female amongst the swarms 

 of males. I have bred this species. JP. marginatus, Pictet, 

 is a distinct species.
