 two or three tiny black bristles, its ventral margin very slightly bent 

 below before the middle of the length ; style-like portion (incomplete) 

 darker. Eyes bare, with the facets all equal in size, in death deep 

 purplish black : when .seen from above the hind margin nearly straight 

 and slightly longer than the frontal margin, the outer margin moderately 

 convex evenly, the top angle about 105 and the frontal angle 60 ; 

 in profile elongate-oval*' with the angles all rounded, the frontal and 

 hind margins rather conspicuously convex and the lower margin 

 strongly curved below; when seen from in front about as wide as deep, 

 the facial margin very slightly convex and slightly shorter than the 

 frontal angle about 145, the top angle about 85, and the lower angle 

 about 110.

 suture, the pubescence numerous short and black ; humeri lighter and 

 bearing rather numerous long whitish grey pubescence; praealar calli 

 more blackish, covered -with numerous long black pubescence which 

 becomes conspicuously shorter and sparser at about the upper half on 

 where there are some short recumbent shining whitish hairs inter- 

 mixed ; postalar calli more brownish, covered with short black 

 and pale hairs, and at the poslero-outer margin there is a dense slightly 

 long pale fringe, the similar but shorter and less conspicuous one at 

 near the upper wing-base; pleurae conspicuously obscured by a grey 

 tomentum and covered with numerous short (but longer than that on 

 the thorax) whitish soft pubescence which becomes blackish,: much 

 longer, and more conspicuous on about the posterior half of the
