The cepthalothorax is of ordinary form ; its colour is a deep rich yellow-brown, slightly tinged with reddish ; the caput is not elevated, being of the same general convexity as the rest of the cephalothorax ; looked at in profile there is a slight hollow between the occiput and the thoracic junction : the height of the clypeus is two thirds that of the facial space ; it is impressed transversely just below the eyes, and is a little prominent at its lower margin, and there is a narrow longitudinal indentation running backwards from behind each lateral pair of eyes. The eyes are in the usual position, of moderate size, and do not differ greatly in their relative proportion; the hinder row is the longest and most curved, and the eyes composing it are equidistant from each other; those of the fore central pair are very near together, but not contiguous to each other, each of them is separated from the hind central eye nearest to it by an interval rather greater than that which divides the hind centrals, but equal to that which separates it from the fore lateral on its side; those of each lateral pair are seated obliquely on a strongish tubercle. The legs are of a bright reddish orange-yellow colour, furnished pretty conspicuously with hairs, and a few very slender tapering erect inconspicuous bristles; they are long and tolerably strong, their relative length being 4, 1, 2, 3, those of the fourth pair being distinctly the longest; the undersides of the fore part of the tibiae of those of the first pair are a little incrassated and furnished more thickly with hairs than other parts. The palpi are not very long, but of moderate strength, and similar in colour to the legs ; the cubital joint is short, and rather abruptly bent downwards : the radial joint is of very remarkable form ; the margins both before and behind on the outer side, which is a little prominent, have a series of about five small tooth-like tubercles, each of which is furnished with a single bristly hair; the inner side is produced into a very long, strong, irregularly formed apophysis, the extremity of which is a little curved and not very sharply pointed; the outer margin of the extreme half is of a corneous nature, and its hinder extremity is pointed and prominent; when looked at from the front, the radial joint and its apophysis look very much like an elongated digital joint with a large and somewhat circular piece taken out of its outer side near the base ; within the hollow formed by this emargination is a short, strong, curved black spiny process; the digital joint is of tolerable size, appended to the radial at some little distance from its hinder extremity; the palpal organs are complex, and (among others) have a strongly curved sharp-pointed corneous process near their extremity; the radial and digital joints are slightly tinged with brown. The falces are strong and of tolerable length; they are similar to the legs in colour, and armed on the inner margin towards their fore extremities with three sharp teeth close together ; the fangs are rather weak. |
