Prothoracic lobes elliptical, well separated, brownish, clothed with narrow, 

 golden scales below, golden-brown ones above and pale bristles. Mesonotum 

 black, a broad median stripe of narrow curved golden-brown scales, a detached 

 stripe of similar scales on each side on posterior half, sides of disk and ante- 

 scutellar space clothed with pale brassy scales; bristles moderate, black, those 

 posteriorly and at the roots of the wings yellowish white. Scutellum trilobate, 

 brownish, clothed with small, narrow, curved, pale brassy scales, each lobe with a

 pruinose, nude. Pleurae gray, the coxae pale brown, clothed with narrow, ellip- 

 tical, flat, dull yellowish white scales and short pale bristles, the prothoracic 

 epimera clothed with narrow golden brown scales. 



Abdomen subcylindrical, flattened, the posterior segments tapered; dorsal 

 vestiture nearly wholly of dull ocherous white scales intermixed with a few 

 black ones, these latter predominating along lateral margins, forming an ill- 

 defined stripe becoming obsolete towards the tip ; venter similarly colored, the 

 black scales forming an ill-defined median longitudinal stripe. Cerci black. 



Wings rather broad, hyaline; petiole of second marginal cell nearly half as 

 long as its cell, that of second posterior cell about as long as its cell ; basal cross- 

 vein nearly its own length distant from anterior cross-vein, scales of the veins 

 black and yellowish white intermixed, the yellow largely predominating on the 

 basal two-thirds of the costa, subcosta and first vein, the black predominating on 

 third vein, the forks of the fourth and fifth veins and the whole of the sixth vein; 

 outstanding scales linear to ligulate, very long, both black and pale. Halteres 

 pale, with blackish, white-scaled knobs. 



Legs rather long, clothed with pale ochraceous scales, the long outstanding 

 setae black; femora with some black scales on upper side which predominate 

 towards tip; tibiae similarly colored; first tarsal joint clothed with ochraceous 

 scales with black ones intermixed which predominate at tips, the other joints 

 black with basal white rings, the hind tarsi having the basal halves white, the 

 rings narrower on the other legs and nearly obsolete on the last joint of front 

 legs. Claw formula, 1.1-1.1-1.1. 



Length : Body about 7.5 mm. ; wing, 6.35 mm. 



Male. — Proboscis slender, nearly straight. Palpi exceeding the proboscis by 

 about half the length of the last joint; vestiture of ochreous and blackish scales, 

 the latter very sparse, tending to form rings near the false articulation of the 

 long joint and at the apices of the other joints ; apex of long joint and last 

 two joints with long, dense golden and brownish hairs. Antennae plumose, the 

 last two joints long and slender, rugose, pilose, black, the others short, black at 

 the thickened insertions of the hair-whorls; hairs long, dense, brown, shining. 

 Coloration similar to the female. Wings narrower than in the female, the stems 

 of the fork-cells longer, the vestiture sparse. Abdomen long, depressed ; dorsal

 stripe of black and golden brown scales ; lateral ciliation long, fine and dense, 

 pale yellowish. Claw formula, 3.1-1.1-1.1. 



Length : Body 7 mm. ; wing 5.5 mm. 



Genitalia (plate 35, fig. 176) : Side-pieces nearly three times as long as wide, 

 the tips conically rounded. Distal lobe large, prominent, conical, with short 

 setae. Basal lobe a rather large but slightly elevated area bearing numerous dense 

 short setae with tubercular bases; a stout spine with hooked tip within the basal 

 lobe, accompanied by two slender hairs. Clasp-filament slender, attenuated 

 above base, a long stout articulated spine at apex, nearly one-third as long as
