shape. Ler/s brown, with black aud gre}- hairs, and both black 

 and white bristles, the latter less numerous than the black ones. 

 The tips of the tibiae have a few white scales, the metatarsi are 

 nearly wholly clothed thickly \Aith white scales, and there are 

 also a few at the extreme tips of the tarsi. Winr^s brownish 

 grey, rather thickly covered with black hairs, and with a fringe 

 of long black hairs around the whole border except at the tip of 

 the wing, where, for the distance between the lower branch 

 of the 2nd longitudinal vein and the upper branch of the 4th, 

 the black hairs are replaced by long snow-white bristly hairs. 

 rive spots on the wing-border (each consisting of a few silvery 

 white scales, which have a faint bluish tint) are placed as follows: 

 a larger one in the centre of the fore border, the second (a small 

 one) just beyond the first; the third at the end of the lower 

 branch of the 4th longitudinal vein ; and the fourth and fifth 

 at the tips of the 6th and 7th longitudinal veins, the fourth spot 

 being the largest. 



Length 2 millim. 



Described from a perfect unique female captured by Dr. 

 Annandale at Kurseong, 5. vii, 08. 



Eight examples of this species have subsequently been acquired 

 by the Indian Museum, captured by Dr. Annandale at Kurseong, 

 22-29. vi. 10, where he found them running over Ccdadium leaves 

 at dusk, in thick jungle.

d 2 • Body blackish, rather sparsely covered above and below 

 with \\ hitish grey hairs, which are thickest towards the posterior 

 borders of the abdominal segments, and are darker in some 

 specimens. The posterior part of the thoracic dorsum bears long, 

 black, bristly hairs. 



Bead : eyes bronze-black, facets very large ; palpi long, 

 brownish grey, with a few hairs. Antennte 16-jointed, scape 

 thick, 1st joint cylindrical, 2nd globular, both rather thickly 

 beset with some elongate whitish grey scales, with v\hich are mixed 

 some long stiif black bristles, botli of which are less developed in 

 the female. In the male a verj- conspicuous and unique character 

 occurs in the first joint of the flagellum, which is three and a 

 half times as long as the second, sub-cylindrical, slightly narrowed 

 and rounded at the base, and slightly contracted just before the 

 tip. This joint bears on its upper surface a row of six long, 

 strong, black, vertical straight spines, set in raised sockets, followed 

 almost at the apex of the joint by two (perhaps three) other 

 still longer spines springing from a common socket; the under- 

 side of this joint is beset with narrow curved greyish scales. The 

 remainder of the flagellum consists of thirteen subequal, elongated
