CIXIUS PILOSUS. 21 



somewhat sceptical as to their being really distinct. 

 With Mr. Edwards I regard them as varieties of the 

 same species.

General colom* pitchy brown, with rufous edges to 

 the abdominal segments. All keels and carinse yel- 

 lowish. Costal granules scarcely larger, or not larger, 

 than those on the nervures. Three darkish triangular 

 spots on the costa, in addition to those on the stigma. 

 The apical part of elytra more or less suffused with 

 brown streaks. Upper part of clypeus brown between 

 the keels ; the rest yellow. Legs brownish yellow. 

 Anal style large and covered by cottony flocks. 



The var. C. alhicincta is much smaller, and is 

 characterized by a broad band of brown occupying the 

 marginal half of the wing. Two conspicuous yellow 

 lobes occur at the base of the anal style, and the 

 nervures are deeper yellow, with fine punctures. 



The differences between the markmgs of this insect 

 and the normal C. pilosus appear to me to be greater 

 than between some species, but I prefer to accept 

 Mr. Edwards' opinion that such variations are scarcely 

 specific. Nevertheless I have introduced figures of 

 C. alhicincta into my plate, with its genitalia. 



C. pilosus is perhaps our commonest species. Mr. 

 Mosley has kindly sent me many examples from 

 Huddersfield. The insect is generally spread over 

 southern Europe and the counties of England.
