ORGANOMYIA new genus. 



Genotype, Orgaiwmyia frontalis Townsencl new species. 



Allied to both Pseudatractocera and Macromeigenia, differing 

 from former as follows : Male. — Front very prominent in profile, the 

 parafacials and front forming a cone with the base of antennae as the 

 apex. Front at vertex over one and one third times eye width, 

 widening anteriorly. Parafrontals twice as wide anteriorly as pos- 

 teriorly; with three rows of bristles outside frontals, of which the 

 innermost are stronger and extend half way down parafacials, the 

 others extending not so low but far below frontals. Frontalia of even 

 width before ocellar divergence, being same width as base of anten- 

 nas and less than half anterior width of parafrontals. Frontals not 

 very strong, descending to base of third antennal joint. Two recli- 

 nate fronto-orbitals. Outer vertical hardly longer than the occipito- 

 orbital fringe. Parafacials very broad and long, quite equilateral, 

 about as broad as anterior part of parafrontals, and nearly or quite 

 as wide as distance between facialia. Cheeks a little under one half 

 eye height. Facial depression very long and deep, broad all way up, 

 only slightly narrowing above ; epistoma sufficiently produced to 

 bring oral margin even with facialia crests. Facialia bare, rather 

 sharply crested; vibrissae but slightly above oral margin. Second an- 

 tennal joint slightly elongate; third joint very long, equilateral, over 

 five times as long as second; arista curved, thickened nearly to tip, a 

 little over one half as long as third antennal joint, basal joints short. 

 Eyes moderately thickly hairy. Only two or three short discal scutel- 

 lars, a slender decussate apical pair of same length, and only three 

 laterals. No median macrochaetse on first segment, a median discal 

 pair on second and third, a well-marked discal row on fourth. Apical 

 cell closed in margin. Cubitus a little more removed from hind 

 margin. Apical crossvein at point of origin forming sharp right 

 angle with fourth vein, well bent in. Hind crossvein much nearer 

 to cubitus than to small crossvein. Hind tibiae weakly pectinate. 

 Claws very long, conspicuously longer than last tarsal joint. 



Organomyia frontalis new species. 



Length of body, 9 mm. ; of wing, 7 mm. One male, Organ, at north end 

 of Organ Mts., New Mexico, September 2y, 1896 (Townsend). 



Blackish. Head silvery pollinose, epistoma and facial crests brownish- 

 fulvous. Frontalia dark brown. Palpi and first two antennal joints rufous.
