GNOrHOMYIA. 487 



furca ; on tlie 1st lougitudiual vein (very small) a little beyond 

 the previously mentioned spot ; at the tip of the 1st vein ; and a 

 small one at the base of the wing between the 4th and 5th longi- 

 tudinal veins ; also narrowly over all the cross-veins. Halteres. 

 rather robust, stem yellow, clubs black. 



Length 3|-4 millim. 



Eedescribed from several of both sexes in the Indian Museum^ 

 taken as follows : Darjiling, 22-30. ix. 08, captured by me, as 

 well as one (20. ix.08) taken there "at light"; Darjiling, 5-6. 

 yni. 09 (Paiva), and Matiana, Simla district, 8000 feet. 28-30. 

 iv. 07 (Annandale). The species occurs also throughout Europe. 



Ti/2u. The location of this is unknown to me, unless it be in 

 the Meigen collection at Paris.

Genotype, G. tristissima, Os. Sac, his second species : by 

 designation of Coquillett (1910). 



Bead: eyes glabrous, nearly contiguous below, but separated 

 above by a broad convex frons. Proboscis short ; palpi moderate 

 in size, terminal joint longer. Antennce 16-jointed, reaching 

 backwards to the root of the wing in both sexes ; 1st scapal joint 

 long and cylindrical, 2nd always much shorter, of varying width 

 according to the species; flagellum of elongate subcylindrical 

 joints, shorter in some species and more globose, the length of the 

 verticillate hairs varying with the species. Thorax prolonged 

 anteriorly, or shorter, according to the species ; suture distinct. 

 Abdomen normally elongate, linear, subcylindrical. Genitalia of 

 male. consisting of claspers, in which the "lirst joint is much more 

 slender than in Gonomyia, the 2nd (horny) joint being in some 

 species almost linear and pointed ; a second pair of horny appen- 

 dages below the first, shorter and stouter. In the female the 

 ovipositor is peculiarly formed, the upper valves being incrassated 

 and arcuate on the lower side towards the base, the lower pair 

 being very short, about half the length of tlie upper ones, the 

 whole ovipositor having thus rather an unusual appearance. 

 Legs long and slender, microscopically pubescent ; tibiee without 

 spurs; empodia distinct; middle pair of legs rather shorter than 

 the others. Wings normally glabrous.* Two submarginal cells, 

 four posterior cells ; discal cell open or closed. The auxiliary 

 vein ending at a good distance beyond the origin of the 2nd veiii, 

 with the subcostal cross-vein a little more or less distant from its 

 tip. The 2nd longitudinal begins about the middle of the wing, 

 forming a moderate angle, the praefurca, which often turns abruptly 

 upward just beyond its middle, generally about half the length of 



* In at least one foreign species (G. liicfuosa, from North America) uiicro- 

 scopic pubescence occurs towards the tip of the wing.
