Show 1889.] REV. O. P. CAMBRIDGE ON NEW ARANEIDEA. 43 specimen of 3 lines long, 1| lines; breadth of cephalothorax rather over 1 line. Adult male. Length 1-| lines. The sexes are very dissimilar in appearance. In the female the cephalothorax is oblong, caput very large, hinder slope abrupt, upper surface moderately convex; the ocular area occupies at least one third of the whole length of the cephalothorax, and the height of the clypeus is scarcely equal to the length of the area of the four central eyes. The colour is yellow-brown, with a broad dark brown longitudinal band on each side. The whole is clothed with coarsish grey hairs, showing most conspicuously on the lateral margins, on the central space between the dark lateral bands, being especially long and conspicuous at the thoracic junction, and forming some white lines connecting the eyes and bisecting the area of the four central ones. The eyes form a very large quadrangle, whose posterior side is the shortest and its anterior much the longest. They are small, the posterior eyes of the central group largest, the rest apparently nearly equal. Those of the central group are close together at the fore extremity of the quadrangle, but not contiguous, forming a small square or trapezoid, whose anterior side is shorter than the posterior. The interval between the eyes of these two sides respectively is greater than a diameter, while the interval between each anterior and the posterior eye next to it is less than the diameter of an anterior eye. The legs are strong and of moderate length, 1, 4, 2, 3, of a yellow-brown colour; the femora, as well as the tibise of the first and second pairs, nearly black ; in some examples the legs have a somewhat annulose appearance. They are almost entirely destitute of spines, but thickly clothed with hairs, of which many are grey, giving them a hoary look. The tibise of the first two pairs are rather stouter than the rest, and the metatarsi of the first pair, in old females, are of a brightish red hue, those of the second pair less so. Towards the inner side of the metatarsi of the fourth pair is a calamistrum running the whole length of the joint, but much concealed by the other hairs. Falces strong, of moderate length, vertical, subconical, darker in colour than the cephalothorax, and clothed with grey hairs, a band across the base in front being more dense and conspicuously white. The fangs are bright red-brown, but rather weak. The maxillee, labium, and sternum are deep brown, clothed with grey hairs, and of normal form. The abdomen is oval, a little broader in some examples behind than in front; its general colour is more or less bright warm yellow-brown, clothed with grey and other hairs; on the upperside are three longitudinal, more or less well-defined dark brown stripes, of which the central one is the narrowest and least conspicuous, and the lateral ones are often dentated posteriorly. The lateral margins and sides also are dark black-brown, and on the underside are two conspicuous reddish-yellow-brown patches, placed transversely and |
