surface the abdomen is brown, mottled with brown yellow; posterior side of spiracular plates whitish; spinners of the same colour as the legs. The whole body, except the cephalothorax, is copiously furnished with dark hair. Cephalothorax as long as the patella + tibia of a leg of the fourth pair; about 1 mm. longer than broad at its broadest part, and rather more than 1 mm. narrower at the fore-part of the caput than at its broadest part; truncated in front and behind; slightly rounded at the side; pars cephalica high; pars thoracica low; thoracic fovea deep, broad and rounded behind, and narrower and somewhat angular in front; lateral furrows well-marked; caput and thorax distinct. The eyes in two rows, the anterior row bent backwards, and the posterior forwards, the latter longer than the former; the fore-centrals round, and the fore-laterals largish, round, and posited somewhat obliquely, the centrals about as distant from each other as from the laterals; eyes of posterior row longish, round, and posited obliquely, the centrals much smaller than the laterals and almost contiguous to them, and about as distant from the fore-centrals as these are from the fore-laterals; the hind-laterals nearer to the fore-laterals than these are to the fore-centrals; a few bristly hairs behind the ocular area, and a tuft in front of the fore-centrals. Falces very long and strong, projecting 5 mm. beyond the clypeus, strongly convex, almost glabrous on the outer side, and abundantly furnished with bristly hairs on the inner side and in front; claw long and moderately strong; groove with a large number of teeth on each side, those on the inner side large, and those on the outer side minute. Maxillœ strongly diverging, in shape resembling the exinguinal joints of the legs and not differing greatly in length from them, the basal half furnished with short black spines, and the fore-margin with a fringe of fine reddish hair. Lip triangular in outline, about as broad as the base is long, convex, separated from the sternum by a semicircular groove, and armed in front with very short blunt spines. Sternum broadly elliptical, emarginated at the anterior and somewhat pointed at the posterior extremity, the sides somewhat projecting opposite the 1st, 2nd, and 3rd pairs of legs, and behind each projection there is a roundish bald dent. Abdomen broadly ovate, narrowest towards the base, 12 mm. long and 9 mm. broad at its broadest part, and projecting over the thorax. The spinners of each fore-pair near each other; the outer short and truncated, the inner nearly as long again as the outer and rounded towards the extremity; the posterior pair very long, about 6 mm.
