The cephalothorax of this species is massive and, looked at from above, of a short, broad, oval form ; in profile the hinder slope is very abrupt and a little hollow or impressed, the ocular region sloping forwards aud slightly prominent; it is of a deep brown colour, with a not very broad marginal band (running also round the front) of white squamose hairs ; the upper surface of the caput is thickly clothed with brightish and rather coppery-yellow, short, adpressed, squamose hairs; and these are continued in a tapering form to the hinder slope, where they merge in a longitudinal central band of white hairs; the sides of the caput and thorax are thinly clothed with dull coppery-yellow hairs; and the upper surface, as also the ocular area and clypeus, is furnished with longish prominent bristles and strong hairs. The eyes are normal both in respect of position and relative size; the two forming the third or hinder row are rather wider apart than the laterals of the first row, and the area enclosed by these four is about double as long in its transverse as in its longitudinal diameter ; the exact position of the two minute eyes forming the middle row could not be ascertained, owing to their concealment by tbe hairs around them. The legs are strong and moderately long; their relative length appeared to be 3, 1, 4, 2; they are of a dark brown colour (the femora of the first pair of a red hue), furnished with hairs, bristles, and spines, a few of the hairs being white and squamose ; the tarsi of the second, third, and fourth pairs are of a pale yellowish colour, banded with brown; and each has a terminal tuft of hair's beneath the tarsal claw. The palpi are short and rather slender, of a pale yellowish colour, except the posterior halves of the humeral and the digital joint, which are brown; they are furnished with hairs and bristles: numerous squamose white hairs are distributed over the upper surface and sides of the humeral and cubital joints, and a few on the radial; this last is about equal in length to the cubital joint, and its outer extremity is produced into a tapering, blackish, corneous, pointed apophysis. The digital joint is equal in length to the radial and cubital together, and has numerous whitish hairs at its extremity. The palpal organs are simple, not prominent nor highly developed ; a slender filiform blackish spine issues from their base and curves round their inner margin to their extremity. The falces are small, subconical, directed backwards, and of a deep black-brown colour. The maxillee, labium, and sternum are normal in form, and of a deep brown colour, the former tipped with a paler hue. The abdomen is small, oval, thickly clothed with hairs of a yellowish grey, black, and coppery hue, forming a broadish roughly dentate PROC. ZOOL. Soc--1873, No. XV. 15 |
