Our specimens are rubbed, but the cephalothorax is yellowish, 
darker in the eye-region, the whole seems to have been covered 
with white hairs with a few red ones mixed in. The abdomen 
has a medium longitudinal band of greyish-white hairs, on either 
side of which are dark stripes, the outer sides are grey, the ven¬ 
ter and sternum pale. The legs are yellow, in some specimens 
the first pair is darker, especially at the distal ends of the joints. 
The palpi are pale yellow with a black line on each side begin¬ 
ning at the patella. There is a tuft of black hairs behind each 
lateral eye. The abdomen is three times as long as wide. This 
is a larger and hairier species than H. Pikei and has white in 
the middle of the abdomen where pikei has dark brown. It is 
most like IT. bina, but is larger, bina having the abdomen only 
twice as long as wide. Mr. Banks had the type from Arizona. 
Our specimens came from Claremont, California.
