18/6.] REV. O. P. CAMBRIDGE ON EGYPTIAN SPIDERS. 579 



An adult female resembled these last in the general colouring; but 

 her legs were entirely without darker markings; the abdomen also 

 is less spotted, and the lines and bands noticed on the male (except 

 the irregular transverse one on the fore part) are scarcely traceable ; 

 the sides are marked with oblique converging red-brown lines form- 

 ing a vandyke pattern ; and the underside is unicolorous. 



Four males (three adult and one immature), and one adult 

 female, were found on low bushes near Cairo and in Upper Egypt, 

 and appear to me to be new to science.

Adult male, length 1^ line. 



The cephalothorax of this Spider is of a short or round oval 

 form, the site of the fore central pair of eyes being rather prominent; 

 it is uniformly though not very convex above, but, on the contrary, 

 rather depressed and the hinder extremity truncated and higher than 

 the fore extremity ; its colour is dark brown, with an indistinct and 

 abbreviated yellowish bar on either side, leaving a broad central 

 brown band and a marginal band on each side of the same colour ; 

 these, however, all merge into one at the caput where the yellow 

 bars cease. Clvpeus none. 



The eyes are in two curved rows wide apart from each other ; and 

 the curves of both are directed forwards ; the eyes of the hinder 

 row are equal in size, and as nearly as possible equidistant from each 

 other ; those of the fore central pair are rather larger than those of 

 the hinder row, and separated by about the same interval as those 

 of that row from each other, each fore lateral being also nearly the 

 same distance from the fore central eye on its side ; the fore laterals 

 are the smallest of the eight, and each is separated from the hind 

 lateral on its side by a larger interval than that which separates the 

 fore and hind central eyes. 



The legs are very unequal in length and strength; their relative 

 length is 1,2, 4, 3, those of the first pair being considerably the 

 longest and strongest; those of the first two pairs are of a dark yellow- 

 ish-brown colour, the femora being the darkest, and marked obliquely 

 near the middle on the upperside with a yellowish stripe ; those of 

 the third and fourth pairs are of a yellowish colour broadly annulated 

 with brown : the tibiae of the first pair had the stumps, apparently, 

 of spines ; but all the armature, of whatever nature, had been broken 

 and rubbed off. 



'The palpi are short, of a yellowish colour, marked obscurely with 

 brown ; the cubital and radial joints are very short, the latter being 

 somewhat gibbous or pointedly prominent on its upperside at the 

 fore extremity ; the digital joint is rather large, and the palpal 

 organs prominent but simple in structure, with, apparently, a fine red- 

 brown spine coiled round them near the middle ; this spine may
