9. Length, 13. Length of cephalothorax, 5 ; width of 



cephalothorax, 3.8. 

 S (young). Length, 10.5. 

 Legs, S , 1432 ; 9 , 4132 ; in both sexes the first pair is 



the stoutest and the others are nearly equal. 



The cephalothorax is low, broad and fiat, with a depression 

 behind the dorsal eyes. It is wider than the second and third 

 rows of eyes in the cephalic part, but its widest point is in the 

 anterior part of the thorax. The male is not so wide as the 

 female. 



The C[uadrangle of the eyes is one-fourth wider than long, 

 occupies about two-fifths of the cephalothorax and is very 

 slightly wider behind, which is an exceptional thing in this 

 genus. The first row is slightly curved. The eyes are all sep- 

 arated, the middle being nearly twice as large as the lateral. 

 The second row is about half-wa}' between the other two. There 

 is a tuft of black hairs just behind the lateral eye. 



The males that Ave have are not quite mature, but the tar- 

 sus of the palpus is very much enlarged and palette-shaped. 



The abdomen is rather broad and fiat. 



The coloration varies considerablj', but that of the females 

 does not differ from that of the young males. The whole flat- 

 tened upper surface of the body is gray, while the sides through- 

 out the length of cephalothorax and abdomen are black. 

 Looked at closely, the gray color is the result of a mixture of 

 white and red hairs. There is a narrow band of shorter hairs 

 of the same colors around the lower edge of the cephalothorax. 

 Around the eyes of the first row are rings of bright red hairs 

 and some long, black hairs. The clypeus and the palpus of the 

 female are covered with very coarse, long, white hairs. On the 

 abdomen are two pairs of lighter colored spots, surrounded by 

 dark rings. In some examples the pattern comes out more dis- 

 tinctly, the broad band down the middle of the abdomen being 

 red, with the spots and the serrated edges pure white, and
