Totally black, but with the elytra of the female fulvous, or 

 occasionally reddish brown ; clypeus very sharply acuminate, bifid 

 and reflexed ; head clothed with greyish hairs in the male ; pro-

 lanuginose all round the margins, in the central part of the disk 

 are two distinct but small squamulose white patches ; scutellum 

 squamose ; elytra less attenuated towards the apex than the five pre- 

 ceding species, covered with non-contiguous, elongate white scales, 

 intermingled with erect or sub-erect, black, somewhat bristly hairs 

 which are longer and stitfer along the suture ; pygidial part and 

 abdomen entirely covered with white appressed squamose hairs ;

 along the base, and yellowish instead of white ; the elytra have 

 along the outer margins a more or less distinct broad band of 

 whitish scales which also ascends the suture for some distance, 

 and there are a few more scattered on the surface, but not as
