M. W. R. de V. GRAHAM 



(L.) Pilger (von Rosen) (1966 : 81). Imagines June and July in Britain ; earlier in 

 Switzerland (see Delucchi, 1955 : 93). 



Toxeuma sp. indet. 



England : Oxfordshire, Bald Hill, near Lewknor, a few £$ and $$, swept amongst 

 Helictotrichon (Gramineae), 18. vi. 1958 (Graham). 



Females of this form (or species) differ from those of fuscicorne in their distinctly 

 shorter gaster (see key to species). Both sexes are rather larger and darker than 

 typical fuscicorne. I have examined the $ genitalia and $ hypopygium of both 

 forms but find no obvious distinctions. Until the biology of fuscicorne and of the 

 present form are properly known, one cannot say whether the two are distinct 

 species or forms of one.
