 fringe. Antennae with the first joint long, red, black-haired ; the 

 second joint globular, reddish brown ; the third black, shortly conical, 

 not longer than the first two joints taken together, not broadened at 

 base, its terminal style longer than the half of the joint. Palpi and 

 proboscis black, this last projecting for the length of the labelli. 

 Thorax entirely black, with black hairs and golden yellow tomentum 

 on dorsum ; there are no distinct clear stripes on the sides ; collar 

 bright yellow above, black on sides and underneath. Notopleural tufts

 with black base, yellowish hairs and black bristles at the hind border. 

 Squamae dark brown or blackish, with blackish fringe ; plumula

 are entirely black, except on the sides of the first segment, where 

 they are pale yellowish ; tergites clothed with black scales and with a 

 complete band of quite white scales on the base of the 3rd segment, 

 narrow in the middle and broadened towards the sides ; on the 6th
