one-half times as long as broad, narrowed and rounded in front, 
evenly and finely granulate, with two transverse furrows in the 
posterior part, the hind one indented in the middle ; the hairs of 
cephalothorax are distinctly clavate, and on each of the dorsal scutse 
are five strongly clavate hairs in a row. Palpi short and rather heavy, 
the hairs plainly clavate, except those on the fingers; the femur is 
scarcely as long as width of the cephalothorax ; the tibia plainly 
shorter, very convex on inner basal part ; the hand about twice as 
broad as femur, and as long as tibia, evenly convex each side, the 
fingers about the length of hand, stout and slightly curved. The hairs 
on under side of body are simple, but most of those on the basal joints 
of legs are clavate. Abdomen is about twice as long as broad, each 
side slightly convex. Length, 2 mm.

those from the fingers ; femur not as long as width of cephalothorax, 
very much swollen on outer base ; tibia but little shorter and barely, 
if any, wider than femur, rather evenly convex on both sides, the 
greatest inner convexity at the middle ; hand very heavy, twice as 
wide as femur, but scarcely as long as tibia, very much swollen on
