 antennae dark brown, the two basal joints pale testaceous; proboscis and palpi dark 

 brown. Mesonotum dark brown with yellowish scales at the sides, forming a rather 

 diffuse central brown vitta; shoulders brown, separated from the vitta by a narrow 

 line of yellow scales; scutellum brown with yellow bristles; metanotum blackish 

 brown; pleura brown, with small patches of grayish white scales; halteres pale

 scattered white scales, more so apically. Legs with coxae pale brown, femora brown, 

 under side yellowish white, knee dot barely discernible; tibia and tarsi wholly 

 brown; claws uniserrated on all feet; wings hyaline, petiole of first submarginal 

 cell about one-third as long as this cell. Length 4 mm.

Female. Proboscis rather long and slender, subcylindrical ; labellae conically 

 tapered ; vestiture brownish-black; setae minute, curved, black, those on labellae 

 more prominently outstanding. Palpi short, about one-fifth as long as pro- 

 boscis; vestiture of blackish-brown scales and moderate black setae. Antennae 

 filiform, the joints subequal, rugose, pilose, black; second joint a little swollen 

 before middle, its basal two-thirds pale; tori subspherical, with a cup-shaped 

 apical excavation, luteous, brown on inner side; hairs of whorls moderate, 

 sparse, black. Clypeus rounded subtriangular, with a slight median groove, 

 depressed, dark brown, nude. Eyes black. Occiput dark brown, clothed with 

 flat appressed scales, except on median line, where there are narrow curved 

 ones, lustrous pale yellow shading to an indistinct brown spot on the sides, the 

 erect forked scales well back on the nape pale, small and poorly differentiated ; 

 bristles along margins of eyes black, a pale-yellow tuft projecting forward be- 

 tween the eyes. 



Prothoracic lobes elliptical, remote dorsally, dark brown, clothed with pale- 

 yellow scales and black bristles. Mesonotum dark brown, clothed with narrow 

 curved scales, dark bronzy-brown except a narrow anterior border and a pair of 

 rather broad longitudinal, pale brassy yellow, subdorsal stripes, broadened pos- 

 teriorly and becoming confluent upon the antescutellar space. Scutellum trilo- 

 bate, gray, with pale-yellow scales, each lobe with a group of brown bristles. 

 Postnotum elliptical, prominent, brown, nude. Pleurae blackish, coxae luteous, 

 clothed with patches of flat, triangular white scales and rows of golden bristles.

 basal, se.gmental, triangular yellowish-white patches which are continued broadly
