XYSTICUS CAMBRIDGII. 



Thomisus GiMBRiDan, Blackw., Spid. Great Brit, and Irel., p. 

 81, pi. iv., fig. 54. 



The female (which is the only sex at present known of this 

 fine and handsome spider) measuros 3-lOtbs of an inch, or very 

 nearly four lines, in length. 



The sides of the cephalo-thorax are yellowish-brown, mottled 

 with yellowish-white, and with the lateral margins and longitu- 

 dinal band, also of a yellowish-white colour. On oach side, near 

 the hinder part of this band, is a largish black patch. The central 

 marking, behind the eyes, has a curvi-linear, short point at its 

 posterior extremity ; being, howover, very indistinctly traceable, 

 and of a yellowish-brown colour. Just above the falces is a 

 transverse marginal row of short, prominent, bristles. 



The legs are short and strong ; those of tho two first pairs are 

 yollowish-white, marblod, suffused, and patched with red-brown, 

 but least so in front of the femora of tho first pair The colours of 

 the third and fourth pairs are very similar, but differently dis- 

 tributed; being pretty distinctly annulated with yellowish- 

 white, and deep blackish red-brown. The spines are short and 

 strong. The abdomen is rounded, and much broader behind 

 than in front ; the upper side is thinly furnished with short, 

 strong bristles; it is of a dull, rather greyish rod-brown 

 huo, and has no marginal border. The usual dentated band is 

 only traceable by one or two pale, indistinct, slightly oblique, 

 transverse linos ; but thore is a more conspicuous, longitudinal, 

 central, narrow, yellowish stripe, which does not, however, touch 

 either the fore or hinder extremity. The sides and hinder part 

 (above the spinners) are pale yellowish-white ; the former have 

 some indistinct, black, oblique streaks, and tho hinder part is 

 thinly, but rather regularly, spotted with black ; tho under side 

 is suffused with brown.
