CAMBRIDGE ON N E W DRASSIDES. 415 thorax is rather short-oval, constricted laterally at the caput, the fore part of which is rather narrow; its colour is dark brown, a broad central band comprising nearly the whole of the caput, but gradually narrowing to the hinder part of the thoracic portion, as well as a broad band on each side above the lateral margins, being thickly clothed with short white hairs. Looked at in profile, the binder slope of the cephalothorax is abrupt, and from its summit there is a gradual and even slope to the eyes. The eyes are of moderate size, in two almost equally curved transverse rows (the front row being a little the shortest), the curves directed away from each other, and forming a broadish transverse oval area; the eyes of the hind central pair are rather further from each other than each is from the hind lateral on its side, being separated by about an eye's diameter; and the same relative position holds good in regard to the eyes of the front row; those of each lateral pair are placed very slightly obliquely, but are not quite contiguous to each other ; the four central eyes form a quadrangular figure, whose length is greater than its breadth. The legs are moderately long and strong, furnished with hairs and spines; their relative length is 4, 1, 3, 2, the difference between 1 and 3 being very slight indeed; the colour of the first and second pairs is yellow, that of the third and fourth pairs is deep brown, sparingly banded with dull yellowish, the bands clothed with short white hairs ; the tarsi are dull yellowish brown, and each terminates, as far as could be ascertained, with two claws, beneath which is a black scopula. The palpi are not very long, moderately strong, and of a yellow colour, similar to that of the fore legs. The cubital and radial joints are short but of equal length ; the latter is the strongest, and has a narrow, angular prominence on its underside, the upper side being furnished with bristles, hairs, and spines; the digital joint is large, oval, with its fore extremity produced into a rather fine point. The palpal organs are simple, consisting of a large roundish lobe, marked on its surface with sinuous dark lines, and produced in a tapering form at its fore extremity, where they terminate in a spiny-looking reddish-brown point immediately beneath the extremity of the digital joint. The falces are moderately long, not very strong, nearly vertical, and of a dark yellow-brown colour. The maxilla are short and oblong in form, of a yellow-brown colour, and pale yellowish at the extremities. The labium is very short, rounded at its apex, which is of a pale yellowish hue, the rest being darker. The sternum is oval heart-shaped, of a deep yellow-brown colour, sparingly clothed with short whitish hairs. The abdomen is oval, narrower before than towards its hinder part; the upper part and sides are dull black ; on either side of the upper part is a bold longitudinal, somewhat zigzag, broken pattern along its whole length, densely clothed with short white hairs ; the lower portion of the sides is also clothed with white hairs ; the |
