612 REV. O. P. CAMBRIDGE ON EGYPTIAN SPIDERS. [June 20, 



daik blackish -brown band, which sometimes emits a few very short 

 oblique streaks on each side near its hinder extremity. The rest of 

 the upper part and sides are thickly clothed with greyish hairs ; 

 though occasionally the sides have a broad longitudinal rusty or 

 brownish band, marked with one or more indistinct oblique pale 

 lines. 



The clypeus of the male is, in general, densely clothed with white 

 hairs, though in some examples these hairs are rusty red ; the 

 lateral margins also of the cephalothorax have a broad band of white 

 hairs ; and the upperside has two indistinct longitudinal bands of 

 a similar nature. 



The legs are sometimes yellow, without any markings; but in some 

 specimens they are faintly annulated and marked with brown. 



The palpi are short and similar to the legs in colour ; the cubital 

 and radial joints are very short ; the latter is the shortest, and has, 

 at the extremity of its outer side beneath, a strong slightly curved, 

 prominent, tapering and sharp -pointed reddish-brown apophysis ; 

 from its position this apophysis is not easilv seen without consider- 

 able care in examination ; its length is equal to, if it does not exceed, 

 the length of the joint. The palpi are clothed with long white 

 bristly hairs ; the digital joint is of good size, longer than the 

 radial and cubital joints together ; it is of a somewhat oblong-oval 

 form, constricted on its outer side towards the fore extremity, where 

 it has a somewhat truncated appearance. The palpal organs appear 

 to be simple in form, and are of a dark reddish-brown colour. 



This Spider is evidently subject to considerable variety in colours 

 and distinctness of markings. A variety of the female, described in 

 " Spid. Palest. & Syr." /. c. supra as Salticus canescens, Koch, has 

 the longitudinal central band on the abdomen of a rusty red hue, 

 but similar in its form aiid character to that of the male. An 

 example of this variety, resembling exactly the Palestine specimen, 

 was found along with the rest in Upper Egypt. Probably the 

 variation in markings depends chiefly on the hairy clothing being 

 more or less uninjured ; when colours are dependent on pubescerce, 

 these will vary very much according to the length of time since the 

 Spider became adult and has been exposed to the brilliant ravs of 

 the sun on a barren desert. 



Attus oculatcs, sp. n. (Plate LX. fig. 90.) 



Adult male, length 2 lines. 



The cephalothorax is massive, the hinder slope abrupt and slightly 

 hollow in the profile line ; the profile of the upper part of the caput 

 forms a slightly curved line ; and the fore part of the ocular region 

 is rather prominent ; its colour is yellow brown, the ocular area 

 strongly tinged with orange, and the margins black ; the surface is 

 pretty thickly clothed with a depressed yellowish grey pubescence 

 and whitish squamose hairs; the clypeus and the lateral margins (as 

 well as the base of the falces in front) being more densely and 

 regularly clothed with pure white hairs of the same nature. 



The eyes are on black tuberculate spots, in the ordinary position ;
