The lip broader than long, strongly convex; no club-shaped 

 bristles ; it is somewhat rounded anteriorly, with a thick bunch 

 of bristly hairs. On the lower end of the maxillae is a distinct 

 heel with 7 or 8 club-shaped spines. There is a thick divided 

 scopula on all tarsi, the metatarsi of the front two pairs, and at 

 the anterior end of the rear two pairs. All the tarsi are without 

 spines ; the front two pairs of metatarsi are without them ; the 

 other two pairs of metatarsi have a good many spines on both 

 upper and under side. The inferior mammillae are very minute and 

 close together ; in the superior pair the second joint is nearly as 

 long as the first, the third short and hemispherical.
