Show 1893.] SPIDERS FROM ST. VINCENT, WEST INDIES. 695 WackUPPei" SUrfaCe of the cePhalic Part. The under surface is CYBELE, gen. nov. The cephalothorax is rounded, convex and rather high, highest at the dorsal eyes; the cephalic part is plainly inclined. The quadrangle of the eyes is slightly wider in front than behind, is one-fourth wider than long, and occupies two-fifths of the cephalothorax. The middle eyes of the first row project beyond the lateral and almost touch each other; the lateral are a little separated from the middle (more widely in vincenti than in obscura); they are unusually large, almost two-thirds as large as the middle eyes. The second row of eyes is nearer the third than the first row. Cybele bears some resemblance to Amycus, but its general appearance is not so rounded, its sides are more nearly parallel, ana the eyes of the first row are more nearly of a size, the middle ones of this row in Amycus being twice as large as the lateral. It also recalls Hasarius, but in this latter genus the eyes of the first row are much smaller and the thoracic part is flatter. CYBELE OBSCURA, sp. nov. (Plate LXI. figs. 3-3 c.) 3 . Length 7. Length of cephalothorax 3 ; width of cephalothorax 2. 2 • Length 7. Length of cephalothorax 2-8; width of cephalothorax 2. Legs, 3 1,3,4, 2, $ 3,4,1,2, all nearly equally long. The first and second are a little the stoutest. The cephalothorax has its sides nearly vertical in front, but in the thoracic part they are rounded out, more plainly than in vincenti ; its widest point is a little behind the dorsal eyes. The thoracic part falls a very little in the first third of its length and then slants steeply. The first row of eyes is straight. The dorsal eyes are a little smaller than the lateral and are placed on the sides of tbe cephalothorax, which, however, is wider than this row below. The clypeus is half as high as the middle eyes of the first row. The falces in both sexes are vertical, parallel, and rather long and stout, with short fangs. The maxillae are considerably longer than the labium and are widened at the extremities. The sternum is not much longer than wide, but is not so nearly round as in vincenti. In colour and marking C. obscura is a good deal like vincenti. The cephalothorax is bright red, with a white band on each side and a third in the central thoracic region. The abdomen is covered with white and red hairs, giving it a tawny look; the anterior end is black and has two pairs of white bars, one above the other, and a bunch of black hairs projecting toward the cephalothorax. A line of fine white chevrons formed of hairs is faintly visible down the central line of the dorsum. The legs are brown, mottled and barred with red, white, and black. The tarsus and proximal end of the metatarsus of the first are not pale as in viiicenti, and there is PROC. ZOOL. Soc-1893, No. XLVII. 47 |
