down the middle which splits apart in front, showing black be¬ 
tween the points. There are indistinct oblique fawn bands, sep¬ 
arated by black lines, on the posterior sides. Young males and 
females are alike, the light pattern on a black ground being, more 
distinctly outlined than in the mature female. 
Mr. Banks has a pair from Claremont, Cal. Our specimens 
are from Sisson, Mt. Shasta, and Victoria B. C. Count Key- 
serling’s single example was from Utah. 
PELLENES AMICUS n. sp. 
Plate XLYI, figs. 7—7b. 
$ Length 6.3 mm. Legs 3412, nearly equal in stoutness, 
femur of first dark, distal end with white spot on inner face and 
black tuft on outer side; patella and tibia with short brown 
fringe below. Spines, difficult to see, tib. I 3-3 and an an¬ 
terior and a posterior lateral; met. I and II 2-2 and an an¬ 
terior lateral. 
The cephalic plate, lower sides and clypeus are light brown, 
the upper sides and thoracic part dark brown. There is a ridge 
of whitish hairs over the first row of eyes. The falces are dark. 
The abdomen is brown, shading to bright reddish at outer sides, 
base, and apex. In front of the spinnerets are three transverse 
white lines alternating with black, the front two connected at the 
ends. The legs are brown, the first and second having the meta¬ 
tarsus and part of the tarsus light, and the end of the tarsus 
black. The palpi are brown with white hairs at the sides. 
The palpus and first leg resemble the same parts in umatillus, 
and although this species is larger the two might be confused if 
the covering of the abdomen were not different. In amicus this 
is made of hairs, only the • transverse bars over the spinnerets 
being made of scales. In umatillus the abdomen is covered with 
elongated scales, three times as long as wide, except a spot on 
the front middle part of the dorsum which is covered with 
scales which are as wide as long. Mr. Emerton found two 
males on Mt. Shasta, Cal., between 5,000 and 8,000 feet up.
