region being broad, and longer tban tho caput. The relative 

 length of the legs is 4.3.1.2. or 4.1.3.2. ; those of the first pair 

 are very rarely the longest. 



The ocular aroa is broader than long, but scarcely differs in the 

 breadth of its fore and hind extremities. Fakes small ; legs 

 short ; those of the male stoutest. 



The distinction between Euophrys and the next genus (AttusJ 

 appears to be but slight. 



The European species of this genus are rather numerous, but 

 three only have hitherto been recorded in Great Britain.

The length of the male is 1-J- lines, and that of tho female 2 

 to 2£ lines. 



The profile of the upper part of the caput slopes a little 

 forward in a slightly curving lino. The cephalo-thorax of the 

 male is yellowish-brown, tho ocular area black or blackish- 

 brown, clothed with orango-brown hairs, and the eyes of the 

 anterior row are each encircled by an iris of red hairs. 



The legs are brownish-yellow, excepting those of the first pair, 

 which are much the strongest, and of a deep brown colour, the 

 tarsi being white, and clothed thickly beneath the tibiso and 

 metatarsi with longish, coarse, bristly, black hairs. The spines 

 are neither very numerous nor conspicuous. 



The palpi are rather short ; tho humoral joint is black-brown i 

 tho cubital and radial joints yellow-brown, clothed above with 

 coarse, but conspicuous, white hairs ; those of the latter joint are 

 much the longest, and project over the digital joint, which is 

 yellow-brown and of moderate size. Tho palpal organs are
