 the base or sometimes throughout the whole underside ; hind femora 

 covered with numerous but shorter black pubescence and sometimes 

 with some golden yellow hairs intermixed on the upper and lower sur-

 the scutellum) together, with the anal apex broadly rounded, black with 

 narrow grey or yellowish grey tomentose bands on segments, widening

 lowing ones only appearing as small truncated spots ; the sides of the 

 basal two segments broadly yellowish brown, with grey or yellowish 

 grey dust, but the remaining sides hardly pale ; pubescence on the 

 greyish spots and bands glistening whitish or yellow. Ventre blackish, 

 moderately shining, with the first two segments brownish and obscured by
