Thorax stout and short, slightly narrowed apically. Dorsum 

 brownish black but obscured by a greyish tomentum, with five rather 

 distinct yellowish grey or grey stripes of which the middle one is nar- 

 rowest and gradually widened posteriorily, the outer two are broader 

 and slightly thickened at the suture after which they are slightly ob- 

 lique inwards and fused with the median stripe together and extend to 

 the posterior margin at where the median one separated by a brown 

 triangle into two laterals, this brown triangle extending up to near the 

 level of the suture, while the side stripes are broadest and extend 

 from the humeri to the postalar calli passing over the praealar calli, 

 and they are divided into two narrow stripes by a narrow and short 

 conspicuous brown stripe from the postero-upper margin of the praealar 

 callus to the anterior margin of the postalar callus ; pubescence on the 

 disc numerous and depressed, yellowish, intermixed with abundant 

 short and erect black hairs which become somewhat longer and paler 

 at the apical part; humeri mostly covered with whitish pubescence but 

 on the upper part there are some darker hairs ; praealar calli bearing 

 suberect yellowish pubescence with stout black bristly hairs intermixed 

 all over the surface ; pubescence on the space between the humeri 

 and praealar calli longer than the disc and almost all suberect but 

 near the suture there is somewhat depressed yellow pubescence ; just 

 above the wing-bases and on the postero-outer margins of the postalar 

 calli there are long somewhat conspicuous greyish tufts of which the 

 posterior one is more conspicuous and much longer ; scutellum short 

 and transverse with rounded posterior margin at where the pubescence is 

 mostly pale yellowish forming a more or less distinct fringe, the pub- 

 escence on the rest of the 'scutellum numerous and black with some 

 yellowish hairs intermixed. Pleurae obscured by a grey tomentum but 

 more or less tinged with yellowish especially on the upper part, cover- 

 ed with long and rather dense whitish pubescence which becomes 

 slightly longer and much denser and is rather greyish on the upper 

 part, and on the mesopleurae there are some long blackish hairs scat-
