Show 1899.] NEW EXOTIC ARANEIDEA. 527 slightly flattened, but with a gibbosity at the base on the outer side ; colour like that of the cephalothorax, and furnished in front with granulations ; fangs short, base strong, the rest weak. Palpi short; radial joint about equal in length to the cubital ; at its fore extremity on the outer side is a strongish apophysis whose termination rather abruptly diverges outwards, and is tapering, apparently somewhat concave, and its point slightly obtuse or not very sharp ; another apophysis on the underside is short, broad and obtuse. Digital joint of moderate size and broad-oval form. Palpal organs consist of a large, simple, prominent circular corneous lobe, forming a strong whorl with a long slender spine issuing from its posterior extremity and encircling the lobe round its inner and on to its outer side, iu close contact with the margin of the digital joint. The colour and armature of the palpi are similar to those of the legs. Maxillce, labium, and sternum similar in colour to the cephalothorax ; tbe tw*o latter, however, are slightly suffused with blackish. Abdomen short, broad, broadest behind, tolerably convex, furnished with short strongish spiny bristles on the upper margins, those above the spinners issuing from small tubercles. Colour yellow-brown, obscurely marked and suffused with blackish ; on each side towards the hinder extremity are some obscure, roundish, dull yellow-browmish spots disposed in several oblique rows. Spinners short, inferior pair strongest. Anal tubercle strong and 2-jointed. Hab. Ceylon. Beceived from the late M r . G. H . K . Thwaites. BOLISCUS DECIPIENS, sp. n. (Plate XXX. fig. 9.) Adult female, length If lines or 3*5 m m . Cephalothorax as broad or broader than long, very convex and highest at the beginning of the hind slope, which is abrupt and steep ; thence to the fore-margin of the clypeus the profile forms an even but not very strong curve. The height of the clypeus is less than half that of tbe facial space. Colour brownish yellow mottled with red-brown, darkest on the sides. The surface is covered with granulations and small tubercles; on each side of the hinder slope is a small but rather conspicuous group of 5-6 small conical white tubercles. The eyes are small, and in two transverse curved lines forming a large crescent-shaped area similar to that of Philodromus. Tbe anterior row is the shortest and its curve the strongest; the convexity of the curve is directed forwards ; the lateral eyes are larger than the central, the fore-laterals largest, the hind-centrals smallest • these last are distinctly farther from each other than from the hind-laterals ; tbe central quadrangle is broader than long, and its anterior side shortest; the eyes of the anterior row are more nearly equally separated, the fore-ceutral pair being perhaps rather nearer to each other than to the fore-laterals. Legs short, robust, 2-1-4-3, angulose; but little difference in length between those of 2-1 and 4-3 respectively, the last being |
