 and white-scaled, of male thin, black ; proboscis black, unhanded. 

 Thorax deep brown, with small reddish golden narrow-curved scales, 

 brown pleuras with snowy white puncta. Abdomen deep brown, with 

 basal white curved bands, aud basal white lateral spots. Legs deep 

 brown, unhanded ; white femoral and tibial apical spots and traces of 

 a very fine indistinct white line on femora and tibias. Ungues of

$ . Head deep brown, with narrow-curved grey scales, somewhat 

 largest in the middle of the head, and black upright forked scales ; 

 small white flat lateral scales and a row of rather long and prominent 

 deep brown bristles projecting from the front of the head, those of each 

 side pointing inwards ; clypeus and proboscis deep black ; palpi thin, 

 rather irregular in form, and clothed with black and white scales. 

 Thorax deep brown, clothed with narrow-curved reddish golden scales, 

 some grey ones in front near the head, another small patch in front 

 of the roots of the wings, pale ones over the roots and before the 

 scutellum ; scutellum with pale dull creamy narrow-curved scales, with 

 two series of border-bristles, the larger deep brown, the smaller pale 

 golden ; prothoracic lobes with narrow-curved pale scales, and some 

 brown chaatas ; pleurae deep brown, with patches of flat-pointed white 

 scales and short golden bristles here and there. Abdomen deep 

 orange-yellow, clothed with deep blackish brown scales with violet 

 reflections, and with basal white curved bands, those of the second, 

 third, and fourth segments being in the form of almost median curved 

 spots ; all the segments with basal white lateral spots ; border-bristles 

 small and pallid, many pallid hairs at the sides of the body ; venter 

 mostly white, scaled with black. Legs deep black, the apices of the 

 femora and tibiae with a white spot ; also on the femora and tibiae is a 

 rather indistinct ventral white line ; ungues small, equal, and simple. 

 Wings with the first submarginal cell longer and narrower than the 

 second posterior cell, its base nearer the base of the wing than that of 

 the latter, its stem varying from one-third to one-half the length of the 

 cell ; stem of the second posterior about two-thirds the length of the 

 cell ; the posterior cross-vein from one and a half to twice its own 

 length distant from the mid ; the seventh vein with scales which vary 

 in number from ten to about fifteen. Length, 3-5 to 4 mm. 



$ . Head clothed with narrow-curved pale scales, a more or less 

 prominent median bare line ; clypeus and proboscis deep brown ; 

 antennae grey, with deep brown bands and verticillate hairs. Palpi 

 deep brown, the apical segment acuminate, last two segments hairy, 

 the antepenultimate segment thin and weak, with a trace of a pale 

 band upon it, hairs black ; two apical segments equal. Thorax very 

 similar to the female, but does not show the pale scales. Abdomen 

 banded as in the female, narrow, with rather scanty long pale brown 

 hairs ; the apical segment with scattered creamy scales, the penulti- 

 mate with the pale basal band extending down each side of the seg- 

 ment. Fore and mid ungues unequal, both uniserrated, hind equal, 

 simple, and small. Wings with the seventh vein apparently not scaled 

 (/. e. only a fold and no true vein). The first submarginal cell consider-
