Show 3/2 REV. O. P. CAMBRIDGE ON NEW DRASSIDES. [Julie 2, dentations are well marked, and suffused with black-brown and dark dusky yellow-brown. The sides of the cephalothorax are furnished with pale dull yellowish adpressed hairs. The eyes are in the usual position, two rather widely separated divergently curved lines of four eyes each ; the central eyes of the hinder row are smaller than the laterals, oval, and oblique; and the space between them is greater than that between each and the lateral of the same row on its side, these last two being almost contiguous to each other. The height of the clypeus is less than half that of the facial space. The eyes of each lateral pair are widely separated from each other; and the intervals between the eyes of the front row are the same apparently as that between those of the hinder one. The legs are rather long and strong; their relative length is 4, 1, 2, 3 ; they are of a brownish-yellow colour, furnished sparingly with hairs and a few, mostly slender, spines. The palpi are short, strong, and similar in colour to the legs : the radial and cubital joints are both short and of about equal length ; but the former is the stronger, and has its outer extremity produced into a strong apophysis, whose length is about a third of that of the digital joint and longer than the radial joint itself; the extremity of this apophysis is flattened, curved, and pointed; and a little way from the extremity is a corneous-looking, sharp-pointed, hooked prominence directed outwards and backwards: the digital joint is strong, equalling in length the humeral one, and exceeding the radial and cubital together ; it is oval, drawn out at its fore extremity. The palpal organs are well developed and rather prominent, but not very complex, with a slender curved filiform spine issuing from their fore extremity. The falces are moderate in length and strength, vertical, conical, and of a deep red chestnut-brown colour. The maxilla and labium are of normal form, and of a dark yellow-brown colour, the extremities of the former being whitish. The abdomen is of an oblong-oval form, thinly furnished with hairs ; the upper part and sides are of a sooty brown colour, marked with numerous pale whitish drab spots and blotches somewhat symmetrically arranged; some of them form some transverse broken angular bars or chevrons on the hinder half of the upperside, the dark intervals forming transverse curved bars, at the extremities of which on either side is an circular depressed spot of a darker hue. On the fore half of the upperside is an elongate central band of a deep sooty brown, on either side of the posterior part of which are three more conspicuous depressed spots in a parallel line. The underside of the abdomen is of a pale dusky drab-yellow hue, with the plates of the spiracles large and of a yellow-brown colour ; two irregular blackish lines run from this point, a little converging towards the spinners, which, however, they do not nearly reach. The inferior pair of spinners are long, strong, and of a yellow-brown colour ; those of the superior pair are paler and not half the length of the inferior. A single adult male of this distinct species, which is allied to both |
