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 iudistinct 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 easily seen without considerable 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." I. c. supra as Salticus canescens, Koch, has the longitudinal central band on the abdomen of a rusty red hue, but similar in its form and 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 j when colours are dependent on pubescence, these will vary very much according to the length of time since the Spider became adult and has been exposed to the brilliant rays of the sun on a barren desert. ATTUS OCULATUS, 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 |
