angle with itself, the frontal angle about 135°, the upper angle about 

 90 , and the lower angle about iOO° and rounded. 



Thorax stout and roundish, about as long as wide, black, covered 

 with greyish tomentum, and bearing four indistinct but rather broad 

 stripes in which the middle two more inconspicuous and obscurely 

 fused from one another leaving only a very faint line black median 

 stripe about the anterior half, while the lateral two are rather well-de- 

 fined and extend from the humeri to the postalar calli, passing on the 

 praealar calli ; pubescence on the disc short depressed yellowish, inter- 

 mixed with abundant short erect black hairs which become somewhat 

 longer and sloping and paler about the anterior part, the yellowish 

 pubescence conspicuous only in the well-preserved specimen ; humeri 

 obscured by whitish grey tomentum and covered with long greyish 

 hairs ; praealar calli moderately covered with grey tomentum and furn- 

 ished with numerous long black stout hairs on the lower half but on 

 the upper half shorter curved yellow hairs which usually extend on 

 the part between the humeri and praealar calli ; postalar calli slightly 

 reddish, obscured by a grey tomentum, covered with short black and 

 yellowish hairs, and furnished with a moderately long dense tuft of 

 whitish hairs at the posterior margin, the similar but smaller tuft just 

 above the wing-base ; scutellum rather large, somewhat semicircular, 

 covered with dense whitish grey tomentum, and with yellowish pubes- 

 cence which becomes longer whiter and much denser along the margin. 

 Pleurae black, but quite obscured by a whitish grey tomentum, and 

 covered with white pubescence which is intermixed with a few incon- 

 spicuous but stout black hairs on the rnesopleurae ; on the postero-upper 

 margins of the rneso- and meta-pleurae there are conspicuous white 

 tufts of long somewhat shaggy hairs, and on the prothorax and ptero- 

 plearae there are abundant long white hairs all over the surface. 



Wings hyaline, but slightly obscured by a pale greyish tinge, 

 and shaded with yellowish brown tinge on the cross-veins ; veins brown, 

 of which the mediastinal and postical veins somewhat yellowish ; costal
