Female. — Proboscis moderately long and stout, subcylindrical, uniform, 

 labellse conically tapered; vestiture black; setae small, curved, black, those on 

 labellse more prominently outstanding. Palpi short, about one-fifth the length 

 of the proboscis; vestiture black, tips very broadly white-sealed above. An- 

 tennae filiform, the joints subequal, rugose, pilose, black, second joint fusi- 

 form ; tori subspherical, with a cup-shaped apical excavation, blackish, clothed 

 with broad silvery-white scales on nearly the entire surface; hairs of whorls 

 rather long, sparse, black. Clypeus prominent, rounded triangular, convex 

 with a slight median impression, sordid-brown, clothed with broad silvery- 

 white appressed scales. Eyes black. Occiput blackish, clothed with broad 

 scales, blackish-brown on the sides, a silvery-white median dorsal stripe 

 (sometimes divided, showing a black median groove) which is continued for- 

 ward between the eyes to base of antennae; eye-margin narrowly silvery-white 

 scaled ; two white bars traversing the dark area well down on the sides ; some 

 pale-yellowish, erect, forked scales well back on the nape. 



Prothoracic lobes elliptical, remote dorsally, clothed with silvery-white 

 scales in the middle, black scales above and below, and with many black 

 bristles. Mesonotum black, clothed with narrow, curved bronzy-brown scales, 

 a very short white line in the middle at anterior edge followed by two narrow 

 silvery lines which are continued almost to the antescutellar space, a broader 

 silvery-white band on either side, strongly curved outwardly and forming a 

 crescent to beyond middle of lateral area, where it is joined to a fine white line 

 which continues to posterior margin; antescutellar space edged with white, a 

 short median stripe before antescutellar space ; a white patch at roots of wings. 

 Scutellum trilobate, densely clothed with silvery-white scales except apex of 

 middle lobe, which is brown; a group of coarse brown bristles on each lobe. 

 Postnotum elliptical, prominent, brown, nude. Pleurae and coxae brown, clothed 

 with patches of flat silvery-white scales and rows of pale bristles. 



Abdomen subcylindrical, tapering posteriorly; dorsal vestiture black with a 

 slight greenish reflection, a narrow white band not reaching sides at base of 

 each segment except on the last, a row of silvery-white, triangular, lateral 

 segmentary spots, the points of the triangles touching bases of segments ; flrst 

 segment yellowish-white scaled, a few black scales at the sides, and with many 

 fine pale hairs; venter yellowish silvery-white scaled with a few black scales 

 intermixed, sixth segment with broad apical black band, seventh segment 

 entirely black beneath. Cerci black. 



Wings moderate, hyaline ; petiole of second marginal cell much shorter than 

 its cell, that of second posterior cell somewhat longer ; basal cross- vein distant 

 more than its own length from anterior cross- vein ; scales brown, the outstand- 

 ing ones broadly linear, those on second vein denser and broader. Halteres 

 yellowish-white. 



Legs rather slender, moderately long; femora black, white beneath at base, 

 front and middle pair with a broad white line on inner side, hind pair with a 

 fine white line on outer side; knees white; tibiae brownish-black; hind tarsi 

 with rather broad white rings at bases of joints, the last joint entirely white;
