Female adult, length 8| lines. Cephalothorax flattened, oblong oval, strongly compressed laterally at the caput, which is rather produced ; the normal furrows and indentations are well marked ; the colour is deep brown, with a broad yellow thoracic margin, and reddish-yellow patches or suffusions at the junction of the caput and thorax; the brown portions are thickly clothed with a short adpressed light grey pubescence, among which are some short erect dark bristles. Eyes eight, not very unequal in size, in four pairs near the extreme upper fore margin of the caput; those of the two central pairs form an oblong figure, the eyes of the fore side being the largest of the eight, and slightly nearer together than those of the hinder side, though, owing to their larger size, they form a line of equal length ; the eyes of each lateral pair are contiguous, placed obliquely on a small tubercle, and are more nearly in a straight line with the eyes of the fore than of the hind central pair. Legs long and strong, of a deep red or chestnut-brown colour, with bands of short light grey hairs, furnished, not very thickly, with hairs, bristles, and small spines; each tarsus ends with three claws, the two superior ones strongly pectinated; and beneath them are some supernumerary opposed ones. Palpi yellowish, clouded and striped with red-brown, furnished with hairs, coarse bristles, and fine spines; and each ends with a curved pectinated claw. Falces moderately long, strong, vertical, conical; of a deep brown colour, slightly tipped with yellow. Maxillee short, strong, enlarged near their middle, round at the extremities; of a rich black-brown colour, broadly terminating at the upper extremities with yellow. Labium short, broad, and subtriangular; it is of a black-brown colour at the base; and the apex, which is blunt in form, is yellow. Sternum heart-shaped, slightly indented on its edges ; it is of a deep brown colour charged with a large and somewhat cruciform yellow marking ; and the whole is thinly clothed with fine grey hairs. Abdomen large, of an oblong-oval form, flattened but irregular on |
