AET. 9 DIPTERA FEOM AMERICA, ASIA, AND JAVA AL.DRICH 17 



Remarks. — Described from five males and 15 females, reared from 

 the locust Valanga nigricornis Burmeister, at Gedangan, central 

 Java, by F. Verbeek, December, 1929, and sent to the National Mu- 

 seum by Dr. S. Leefmans, of Buitenzorg, to whom a pair of para- 

 types are returned. 



The species is very similar to those that in Europe have been re- 

 garded as belonging to the genus Blaesoxipha. The male is readily 

 distinguishable from all European forms known to me, in having the 

 forceps much broader toward the base and the anterior claspers with 

 a lobe on the front near the middle.

 ever, very small, the lowest at middle of second antennal joint ; para-

 oye height. Front in both sexes wide, about 0.35 of head width, and 

 with proclinate orbitals in both; pollen of head mostly white, but
