380 EMPIDuE. 



bristles. Abdomen black, moderately shining, practically bare ; 

 venter similar. Genitalia rather large, black ; a pair of claspers 

 with large basal joint with long crooked terminal black hook-like 

 appendages. Legs brownish yellow, fore coxa? half as long as the 

 femora; anterior femora incrassated, hind femora not thickened, 

 long; tarsi more or less brown; all the legs minutely pubescent. 

 Wings microscopically setulose, pale brown, no stigma ; venation 

 normal, anal cell absent; the anal cross-vein present but incom- 

 plete. 



Length, 2k mm.

Genotype, Drapetis exilis, Mg. (Europe). 



Head not so broad as thorax, but broader than high, rather 

 short ; eyes microscopically pubescent, separated in both sexes, 

 sometimes narrowly just above antenna?, below which they are 

 contiguous or nearly so, facets of uniform size. Proboscis short, 

 vertical ; palpi one-jointed. Antenna? inserted just above the 

 middle, very short,* especially 1st joint ; 2nd joint slightly 

 broader at tip, bristly ; 3rd conical, varying in length but always 

 comparatively short, pointed, with a rather long apical arista, 

 which is said to possess a microscopic basal joint. Thorax 

 approximately square, with rounded corners, generally moderately 

 arched, in some species more so ; dorsum with fine pubescence. 

 Ohaetotaxy apparently slightly variable, generally some dorso- 

 central, acrostichal, and notoplenral bristles, with often a postalar 

 and post-humeral bristle ; scutellum with two bristles ; metapleura 

 practically or quite bare. Abdomen short and robust, 8-segmented, 

 ending in male in a knob-like genital organ, in female in a point. 

 Legs comparatively short and strong, fore and hind femora rather 

 thickened ; hind tibia? sometimes ending in a projecting tooth. 

 Legs shortly pubescent, with a few bristles ; tibia? spurred or not,t 

 hind pair with a small bump at tip ; empodium very small, seti- 

 form. Wings short, rounded, anal angle well developed ; auxiliary 

 vein inconspicuous, short, ending free ; 1st, 2nd, and 3rd longi- 

 tudinal veins slightly curved forward ; 3rd, 4th, and 5th veins 

 simple ; a trace of an anal vein, but indistinct or unappreciable 

 at base. Discal cell absent ; 2nd basal cell much longer than 1st, 

 truncate ; anal cell absent. 



* Melauder describes the antennae of this and seme kindred genera as 

 two-jointed. The 1st joint is often so small as to be overlooked, or it may 

 conceivably be reduced to a mere facial protuberance. 



t Schiiier says that the front tibia; are spurred.
