208 BOMBTLIIDJE. 



is very sparsely covered with very short yellowish scales, which 

 probably even in perfect specimens never wholly cover the surface; 

 scales at sides of thorax more yellow than orange. Posterior calli 

 prominent, ferruginous, covered with irregular small black bristles, 

 with some long yellowish-white scaly pubescence on the outer 

 •side, and there are four powerful long black spines placed close 

 together and directed horizontally backwards. Scutellum ferru- 

 ginous brown, with an irregular double row of black spines on 

 posterior margin, and short yellow scales round the dorsum, which 

 is quite bare in the middle, both of scales and hairs. Abdomen 

 black, covered with microscopic black scales ; thick, scaly, whitish 

 pubescence at the sides of the 1st segment; at the base of the 

 2nd segment (which is the widest) a wide band of scaly yellowish- 

 white pubescence ; the remaining segments also bear similar bands 

 at their bases of more whitish scaly pubescence, this being 

 shortest ou the 5th segment ; on the posterior borders of the 1st, 

 Gth, and 7th segments a row of rather strong black bristles, 

 directed backwards. Genital organ distinct, black, encircled 

 towards the posterior part and at the sides by a rather thick 

 fringe of orange hairs ; the tip itself more greyish, and bearing- 

 two vertical rows (containing seven in each) of rather long, 

 roseate scales, like the teeth of a comb. Venter black, nearly 

 covered, except towards the tip, with close, nearly snow-white, 

 scaly pubescence, the tip with black bristles. Legs black ; coxas 

 with yellowish-white scales and distinct black bristles: femora 

 with similar scales and short black hairs, the middle pair with 

 two rows of short, distinct spines on underside ; the hind pair 

 with a similar row ; fore tibiae bare, middle tibiae beset somewhat 

 irregularly with four rows (one on each side) of conspicuous but 

 ■moderately short bristles ; hind tibiae closely beset with elongate 

 dirty white scales, lying close to the surface, and intermixed with 

 strong, moderately short, black bristles, and with an irregular circlet 

 •of black spines at tip, most of them on the underside ; tarsi minutely 

 but closely pubescent, with a row of minute spines below, being 

 longest on hind pair. Wings pale grey, costal cell and the basal 

 parts of all the veins ferruginous brown; costal vein apparently 

 bare, but viewed microscopically, it presents a very closely-placed 

 row of minute black spines, which are conspicuous on the extreme 

 base of the costa, where they are larger and are intermixed with 

 close-lying, dark greyish scales ; at the extreme base of the costa 

 is a very powerful, thick, black, curved spine. Tegulag bright 

 orange, with a fringe of elongated scales, which are black on 

 outer part of the edge and dirty white towards the base; alula 

 of wing grey, with a fringe on posterior border of grey scales, 

 which continue for a short distance along the posterior margin of 

 the wing; halteres with stem brownish, club very pale creamy 

 -orange.
