 third, greyish pollinose ; the first foui;segments thickly clothed

 segment thickly clothed with longer golden hairs ; the second 

 segment with an oblong patch of black hairs on each side,

 an ill-defined black band, due to short black hairs mingling 

 with the ferruginous ones; posterior margin of second and third 

 segments narrowly whitish. Legs: first two pairs of coxfB 

 black, greyish pollinose, the anterior pair clothed externally 

 with pale yellow hairs and in front with black hairs, the
