Aledium-sized or smallish, dark-coloured species. — Dorsum of thorax hlachish slate- 

 coloured, somewhat shininf/, with two conspicuous, f/rey, admedian, lonffitudinal 

 stripes; dorstim of ahdoinen clove-hroum, hind border of first segvwnt and greater 

 part of second and third segments greyish cinnamon-rufous, hind borders of four I h 

 and following segments greyish, isahella-colonred and, except in case of last segment, 

 clothed on each side with appressed, whitish hair; wings faintly tinged with drah, 

 stigma narrotv and elongate, mummy-lmnon ; legs clove-brown or blach, tibiae, ex- 

 cept tips of middle and hind pairs and rather less than distal lialf of front pair, 

 cream-coloured, and clothed with appressed, glistening white hairs. 



Head grey (subcalhis when denuded dark brown), face, jowls, and basioccipital 

 region clothed with whitisli hair; /coh^ of moderate bi'eadth, about three and a 

 half times as long as broad, inner margins of eyes bordering it almost or quite 

 jmrallel, upper two-thirds of front clothed with short black hair, lower third, on 

 each side of callus, clothed with short white hair ; frontal callus oblong or roughly 

 quadi-ate, often with its upper angles more or less rounded off or otherwise ob- 

 literated, dark brown or chestnut-brown, narrowly separated from eye on each 

 side, and prolonged above into a raised median line ; palpi dusky (mouse-grey 

 or dark grey), clothed on outer side with whitish hair, terminal joint acuminate, 

 moderately stout at base ; first and second joints of antennae greyish clove-brown 

 or brownish grey, clothed with black or blackish hair, third joint more or less 

 chestnut, chestnut-brown, or cinnamon-rufous (sometimes entirely dark brown 

 except at extreme base, sometimes entirely cinnamon-rufous except at extreme 

 tip), expanded portion of third joint moderately broad, not elongate, terminal 

 annuli fairly long. Thorax : dorsum clothed with erect, black or blackish hair, 

 denser on scutellum, in front of suture also with minute, appressed, bufF-yellow 

 hairs ; immediately above base of each wing is a small tuft of whitish hair ; 

 sides and front of dorsum grey, swelling in depression at each end of transverse 

 suture drab-grey ; dorsal stripes rvmning from front margin to presutural groove, 

 liroadening out posteriorly and almost in contact ; pleurae and pectus grey,

 with glistening white hair ; dorsum of second and third segments each with a 

 large, though not sharply defined, clove-brown, median spot, resting on base but 

 not reaching hind margin (occupying approximately anterior two-thirds of each 

 segment) ; on each side of same two segments is a more or less distinct clove- 

 brown blotch (often larger and more conspicuous in case of third segment), in 

 contact with base, but not approaching hind margin nearer than median spot ; 

 immediately behind median spots on second and third segments is a patch of 

 minute, appressed, glistening, whitish hairs, extending to hind margin in each 

 case, while behind each of the lateral spots on the same segments is a larger, 

 transversely elongate patch of similar hair, extending to the posterior angle ; 

 fourth and fifth segments each with a similar patch of minute, appressed,
