Length, 9.5 mm. Bears considerable superficial resemblance to 

 Copecrypta ruiicauda, but may be distinguished therefrom by the 

 generic characters above given. Head entirely silvery white, fron- 

 talia showing very faintly pale brownish, first two antennal joints 

 light brownish yellow, third joint hardly darker, but with anterior 

 terminal border and arista blackish. Proboscis black, shining.

 vittae, and two narrow inner vittae stopping a little behind suture. 

 Scutellum tawny yellowish, darker at base, silvery, with two very 

 strong pairs of lateral macrochaetae reaching beyond base of third 

 abdominal segment, a moderately strong but shorter apical decussate 

 pair, and two lateral weak pairs besides discal bristles. Abdomen 

 faintly blackish on dorsum, pale reddish or brownish yellow on 

 sides, anal segment wholly reddish. All of abdomen more or less 

 thickly silver}- pollinose. showing most on basal half or more of last

EUPELETERIA, gen. nov. 



Erected for Bchinomyia fera Linne, magnicornis Zetterstedt, 

 prcEceps Meigen, etc. Differs from Peleteria Robineau-Desvoidy in 

 lacking the two or three facio-orbital bristles (macrochaetae on para- 

 facials next orbit and separated from descending frontal bristles). 

 Differs from Bchinomyia Dumeril, as restricted, by having abdom- 

 inal macrochaetae not closely set and thorn-like. Body Peleteria- 

 like, not Jurinia-like. 



EUFABRICIA, gen. nov. 



Second antennal joint strongly elongate, fully four times as long 

 as first, much longer than third; third joint strongly convex on 

 front border in profile. Second aristal joint elongate, fully four 

 times as long as wide. Palpi widened and flattened on distal one- 

 third or so, somewhat spatulate. No ocellar bristles. Parafacials 

 wide, front not specially prominent in profile. Cheeks about two- 

 thirds eye height in width. Anterior tarsi of female not more 

 widened than those of other legs.
