Homalomyia, Bouche\ (474) 



Herr Stein gives the following as distinguishing 

 Homalomyia from all other Anthomyids : 



The presence of a more or less long and thick 

 pubescence on the inner side of the mid tibiae in 

 the males, that is of fine somewhat shaggy hairs 

 as distinguished from the short flat-lying orderly 

 bristles of other families ; and in the female the 

 absence of the crossed frontal bristles, and the 

 presence of two upper and outer fronto-orbital 

 bristles in addition to the usual row of fronto- 

 orbital ones, namely, one strong bristle about on a 

 line with the front ocellus near the middle of the 

 orbit and pointing backwards over the vertex, and 

 another beneath it, nearly half-way down, and 

 pointing outwards over the eye. 



43 (42) (44). Abdomen narrow at the base and broader 



towards the end, the second segment longer than
