GENUS HASAEIUS, Sim. SALTICUS, Blacho., in part, 

 and ATTUS, Camlr., in part. 



In this group the cephalo-thorax is of moderate length in 

 proportion to its breadth but massive and elevated. The thorax 

 is about one-half longer than the caput, and distinctly broador, 

 though there is little or no evident mark of division between them. 

 The ocular area is much broader than long, and very slightly 

 narrower behind than in front. The legs are strong, short, and 

 do not differ much in length ; relatively, they vary both in 

 different species as well as in the sexes of the male species. 

 Commonly the relative length is 1.3.4.2. The falces are of 

 moderate length and strength. 



Three species only have been found hitherto in Great Britain ; 

 of those, one is most probably an introduced tropical spider ; and 

 one only has as yet been met with in Dorsetshire.

The male measures about 2£ lines in length, and the female 

 often attains a length of 3£ lines. 



The cephalo-thorax is of a deep brown colour, dotted with 

 greyish yellow-brown hairs ; the ocular area is black and sur- 

 rounded by a broad, pale band (interrupted in the middle), and 

 clothed with short white hairs. 



The legs are yellowish, or yellow-brown, the anterior portions 

 of the femora and tibiae deep brown. They are much darker in 

 some examples than in others, and are clothed with (among 

 others) numerous greyish-white hairs, and all are furnished with 

 spines. 



The palpi of the male are short, strong, and of a dark, yellow- 

 brown colour, clothed in front with coarsish-grey and other 

 hairs. The radial is rather larger than the cubital joint, and
