Show 416 REV. O. P. CAMBRIDGE ON N E W DRASSIDES. [June 2, underside is bright reddish yellow-brown, sparingly clothed with short white hairs ; the fore part of the underside is covered with a continuous kind of red-brown shield, comprising the two spiracular plates. The spinners are short, blackish, tipped with pale yellowish ; those of the inferior are rather longer and much stronger than those of the superior pair. A single adult male was received several years ago from the Andes of South America. AGRffiCA WALSINGHAMI, sp. n. Adult male, length rather more than 3 lines. This species is very nearly allied to the foregoing, which it resembles in size, form, and general structure; the colour and markings, however, of the foregoing will distinguish it at once from the present Spider. The cephalothorax is deep black-brown, uniformly clothed with short whitish hairs; the legs of the first two pairs have the femora deep black-brown, thinly clothed with short white hairs, the rest dull yellowish, tinged with olive ; the femora of the third and fourth pairs are the same in colour and clothing as those of the first and second; but the remainder is of a dark red-brown, the metatarsi of the fourth pair having a few white hairs dispersed over them ; all the legs are armed with a few fine spines ; and the tarsi have two terminal claws, beneath which is a claw-tuft; the coxal and exin-guinal joints of all the legs are deep blackish brown, as also is the sternum. The falces are stronger than in A. pulcherrima, and are of a deep blackish red-brown colour. The maxilla and labium are dark red-brown, tipped with pale yellowish. The palpi are short, of a dark yellowish-brown colour, the humeral joint the darkest; the radial is stronger and slightly longer than the cubital, of a similar form beneath, as in the foregoing species, but the angularly prominent portion is rather more marked ; the digital joint is large, long, and like that of the foregoing in form ; the palpal organs are also very similar, but there are no sinuous lines apparent on the surface of the main lobe, and the part produced forwards appears to terminate more obtusely, without the spiny point visible in that species. The abdomen is of an oblong-oval form; the greater part of the upperside is covered with a well-defined, oval, coriaceous distinct epidermis of a reddish yellow-brown colour; the fore part is darker than the rest, and is clothed thinly with short white hairs, the rest with short bright yellow-red ones; the sides and hinder part are of a foxy red, clothed with red hairs, and some white ones between the sides and underside; the underside is dark yellowish brown, clothed thinly with short pale whitish hairs. A coriaceous covering of a deep red-brown colour beneath the fore part, similar to that in the foregoing species, comprises the spiracular plates; the spinners are very short, scarcely perceptible without difficulty. |
