blackish, with a reddish tinge on the border, clothed with short 

 bright yellow hair and with a row of black bristles on the posterior 

 border. 



Abdomen obtusely conical; ground colour black. The middle 

 third of the dorsum forms a nearly bare, black centre stripe 

 with a few black hairs ; the outer third on each side is covered 

 with numerous bright yellow narrow elongated scales, lying close 

 together, and extending from the base to the posterior border 

 of the 5th segment, being replaced on the 6th and 7th segment 

 by similar scales which are silvery white; these, seen from behind, 

 appearing to form four silvery spots. The whole abdomen is shortly 

 pubescent with black bristles, and the posterior border of each 

 segment has a row of longer bristles. The sides of the first three 

 segments of the abdomen are clothed with long yellow hair, which 

 almost become scales ; from thence to the tip being replaced by stiff 

 black bristles. Belly black with black bristles and hairs, the 

 major portion of the basal half (except at the sides) being clothed 

 with dense silvery white scales, amidst and above which are silvery 

 white hairs. A genital organ, considerably retracted, is visible, 

 consisting of a pale yellow tubular appendage encircled by a red- 

 dish brown semi-circular plate bearing stiff black bristles on its 

 edges : above this is a thick, sub-conical organ, black, with grey- 

 ish shimmer at the sides, thickly covered with short black spines 

 and cloven at the tip. 



Legs. — Coxse ash-grey, clothed with long pale yellowish hair, 

 with which are intermixed a number of very strong long black 

 spines. Femora black, with small dark grey scales and a little 

 soft, short black hair ; fore pair spineless, middle pair with a row 

 of short bristly hairs above and two short strong spines close together 

 on the under side just beyond the middle ; hind pair generally 

 beset with short black bristles, and with a row of rather strong 

 short ones on under side. Tibiae black, shortly spiny, with minute 

 blackish grey scales, the spines being longest on the hind pair. 

 Tarsi black, minutely pubescent. 



Wings. — Dark brown (deepest along the costa), becoming lighter 

 towards the posterior border, which is dark grey. A violet irides- 

 cence in certain lights. Anal cell narrowly open. Shoulder of wing 

 beset with stiff, short black bristles, and covered at its extreme 

 base with short orange bristles. Tegulae dark brown with a fringe 

 of rather long, very close, bright j^ellow scaly hair. Halteres red- 

 dish brown, knob very distinct, oval, placed in the cup-shaped 

 enlarged tip of the stem, pale orange, with greyish tomentum. 



Described from two specimens, one in the Indian Museum 

 and one in the Pusa collection, both captured at Chapra, Bengal. 



N.B. — I have practically no doubt that this is Guerin's species, 

 although the markings of the abdomen are not quite like his figure, 

 which shows an interrupted dorsal black stripe to the abdomen, 

 with lateral extensions, and in his figure the dark part of the wing 

 is more clearly defined and not so extensive. Moreover it was 

 from Bengal that he described it.
