BRITISH ICHNEUMONS. 



[Casinaria 



This species is a little incongruous in whatever i^enus il be treated in 

 its very small and clonj^ate-oval melapleural spiracles, which are by no 

 means linear, as in Canipophx, at the end of which Thomson places it 

 on the characters of its totally black body clothed with sparse and sub- 

 rigid pubescence, and to which Holmgren later restt^red it on the spira- 

 cular structure, which Tschek, while allowing it in Casinaiia, dc;scribes 

 as kurz-spaltformig and Bridg. -Fitch as "not circular." Schmeideknecht 

 has recently transferred it to the genus Trophocampa, also witii circular 

 spiracles, because the abdomen is apically less clavate tlian in the re- 

 maining species of this genus. 



It seems by no means abundant in norlli and central Europe; Belgium, 

 France, Sweden; "usually found in shady places in woods" (Schm.) ; 

 Gravenhorst knew but a single Berlin male. Bred from Abivxtis grossii- 

 lariala by Raynor (Entom. 1884, p. 67) and on 20th June by Bignell [I.e. 

 1881, p. 140), at Laira in Devon; the cocoon is "of an oval shape, and 

 has the appearance of coarse brown papei-, the apices brown, followed by 

 a blackish zone; the central portion, which occupies one-third, is brown" 

 (Bignell, I.e. 1880, p. 246; cf. I.e. 1884, pi. ii, fig. 11), the two irregular 

 black bands being more or less obscured by a dense and testaceous 

 woolly outer covering. Taken at Oxford by Hamm on 6th June and 

 bred at Bristol by Charbomvier from larvae oiA. grossulariafa. "Captured 

 by Capron at Shere and (mce as late as 15th Se})tembcr by Pilfard at 

 Felden, In my experience this is exclusively an urban insect, frequently
