margin nearly straight (very slightly convex), the hind margin moderately 

 convex, and the lower margin strongly convex ; when seen from in 

 front about as wide as deep, the facial margin very slightly covex and 

 apparently shorter than the. frontal margin, the frontal angle roundish, 

 about 130 , and the top angle about 90. 



Thorax somewhat quadrate with the angles roundish, pale yellowish 

 grey to greyish yellow-brown, with five short very inconspicuous (one so 

 described as no stripe exists) yellow or reddish yellow stripes only at the 

 anterior border of which the lateral pair is usually more distinct, and 

 broadest, and extends from the humeri to the postalar calli, but they are 

 interrupted by the suture and then suddenly narrowed hindwards ; pubes- 

 cence on the disc numerous, short, depressed, pale yellow, intermixed 

 with rather abundant longer erect conspicuous black hairs ; humeri rather 

 distinctly paler, covered with not dense though numerous long pale 

 yellowish grey hairs which become whitish about the inner-lower third ; 

 praealar calli usually darker than the disc of the thorax, clothed with 

 abundant long erect somewhat shaggy black pubescence which is slightly 

 shortened about the upper half or less on where it is intermixed with 

 some yellow recumbent hairs ; postalar calli pubescent as in the disc of 

 the thorax but on the postero-outer margin there is a somewhat yellow- 

 ish tuft of rather dense curved hairs, similar but shorter tuft just above 

 the wing-base and front where are some stout very short black hairs. 

 Pleurae paler than the thorax, usually pale yellowish grey or greyish 

 yellow, covered with numerous not very long yellowish grey or pale 

 brownish yellow soft hairs which become more conspicuous and longer 

 towards the sides ; prothorax covered with numerous longer soft yellowish 

 grey hairs, on the postero-upper margins of the meso- and meta-pleurae 

 .there are much longer dense greyish yellow tufts, and about the postero- 

 upper comer there are numerous long rather shaggy yellowish grey 

 hairs. 



Wings rather distinctly tinged with brown, with the costal cell 

 usually yellowish, and sometimes with the basal part and the submarginal
