British Braconide. 499 
The determination of species is in general not difficult, 
owing to the obvious characters exhibited by the wing- 
veins ; in other respects there is great uniformity. The 
colours are black and piceous brown, relieved in some 
cases with red or testaceous, and are tolerably constant 
in the same species. As in the case of the Opvides, 
good setting is a necessity, especially in the smaller 
species; the characters are mostly derived from the 
upper surface, but the face and the mesopleurz should 
be open to examination. Pinned specimens, and all 
those whose wings cannot be clearly seen, are generally 
valueless.
