CAMBRIDGE ON N E W DRASSIDES. 399 The eyes are of tolerable size and in the usual position; but the curve of each row is nearly equal, making the two rows almost parallel; the hinder row is the longest, and its two central eyes are large, pearly white, and very nearly contiguous to each other, the lateral on either side being separated from them by about the diameter of one of the centrals; the fore centrals are also large, but not quite so large as the hind centrals, though forming a line of the same length, the interval between them being rather more than half of the diameter of one of them; the eyes of each lateral pair are separated from each other by an interval of about the diameter of one of them. The falces are moderate in length and strength ; they are prominent at their base in front, projecting forwards, and are of a dark yellow-brown colour. The legs are rather short, moderately strong, furnished with hairs and spines, the latter chiefly on the two hinder pairs ; their relative length is 4, I, 2, 3, and they are of a yellow colour. The palpi are similar to the legs in colour, deepening to yellow-brown on the radial and digital joints, and they are furnished with hairs and a few black spines. The maxilla and labium are of normal form ; the former is yellow-brown, the latter considerably darker. The sternum is oval, pointed behind, and similar in colour to the cephalothorax. The abdomen is oval, rather truncate before, where it projects a little over the base of the cephalothorax; it is thinly clothed with hairs, and of a dull brownish black hue, speckled and marked with pale yellowish: on the upperside a dusky, elongate, tapering or wedge-shaped marking occupies the central longitudinal line of the fore half: on either side of the hinder or pointed end of this marking are two small, pale, elongate spots; and following it, towards the spinners, in a longitudinal series, are 6 or 7 transverse angular bars or chevrons of a pale dull yellow colour; and the vertex of each of these runs into the angle of the one preceding it. The dark ground-colour of the abdomen is disposed in parallel striae towards and on the sides; and the intervals between the yellowish angular bars themselves form dark broken chevrons. On the underside are two longitudinal and rather pale yellowish lines, which converge at a little distance from the spinners ; and at the extremity of these lines on either side is a curved row of three round pale yellowish spots, more distinct than the rest. The spinners are moderate in length and strength, those of the inferior pair being the longest, and their colour is similar to that of the legs. The genital aperture is large and of peculiar form (vide Plate LII. fig. 24). A single adult female was found by myself at Cairo. DRASSUS PUGNAX, sp. n. (Plate LII. fig. 25.) Adult male, length 3g lines. The cephalothorax of this species is short, oval, rather more pointed before than in many others of the genus, but in other |
