ART. 6 NOTES ON" ORIENTAL SAPROMYZID FLIES MALLOCH 39 



behind each humerus and in the middle two faint brown vittae. It 

 is from Los Banos. Except for the presence of facial spots the 

 description is like that of stemopleuralis, 



I have seen a specimen which I identify as spulphuiiceps from 

 Ceylon. 



Genus KERTESZOMYIA, new genus 



Generic characters. — Head very similar to that of Panurgopsis 

 Kertesz, but the eye is more oblong, the anterior orbitals are directed 

 baclrward, and the face is not protuberant (Fig. 29). Except for the 

 presence of four long strong bristles on lower margin of cheek, the 

 greater length of the upper orbitals as compared with the inner 

 verticals, and the presence of but one sternopleural bristle, the genus 

 is similar to Sapro-niyza. A noteworthy character is the position of 

 the postvertical bristles which are situated far below the vertex, their 

 distance from posterior ocelli being distinctly greater than from 

 ocelli to inner vertical bristles. 



Genofype — the following species. 



KERTESZOMYIA MACULIFRONS. new species 



Female. — Eeddish testaceous, thorax and abdomen shining. Frons 

 not shining except at bases of the bristles, with a black spot on ocellar 

 region and one between each antenna and eye; antennae concolorous 

 with head. Thorax and abdomen immaculate. Wings yellowish 

 liy aline. Halteres yellow. 



Head in profile as in Figure 29; frons with fine surface hairs 

 anteriorly; face almost flat. Thorax with three pairs of dorso- 

 centrals, the anterior pair well in front of suture, a strong pair of 

 prescutellar acrostichals, and very sparse fine hairs, widely biserial 

 presuturally ; scutellum flattened above, subtransverse at apex, with 

 four bristles. Apical bristles on tergites longest on sides. Fore 

 femur without anteroventral comb ; all tibiae with distinct preapical 

 dorsal bristle, strongest on mid pair, the latter with one long apical 

 ventral bristle. Inner cross vein a little proximad of middle of discal 

 cell; ultimate section of fourth vein about twice as long as penulti- 

 mate section; first posterior cell very slightly narrowed apically. 



Length, 4 mm. 



Type.—Q^i. No. 41602, U.S.N.M. Imugin, N. Viscaya (C. F. 

 Baker). 



In Hendel's recent key this genus runs down to Uypagoga., but the 

 latter has the postverticals close behind ocelli, the ocellar bristles long 

 and strong, first posterior cell widened apically, and differs in other 

 respects.
