The legs and palpi are light brown, the legs having some dark rings. The falces are dark brown. The under surface is light brown. This spider is immature. It is not a very good Euophrys, but as it is near that genus w e put it there provisionally. CYDONIA, gen. nov. The cephalothorax is low and is almost flat above. The cephalic part is very slightly inclined, and the thoracic part falls scarcely at all in the anterior half and then slopes abruptly to the margin. The sides are narrowest in front; they widen a little just behind the dorsal eyes and then contract gradually as they pass backward; in the cephalic part they slant inward, but in the thoracic part they are gently rounded. The quadrangle of the eyes is wider behind than in front, is one-fifth wider than long, and occupies one-half of the cephalothorax. The four anterior eyes are placed close together in a straight row, the middle being nearly twice as large as the lateral. The second row is nearer the first than the third row. The dorsal eyes are fully as large as the lateral eyes of the first row and are placed on the margin ©f the cephalothorax. The labium is longer than wide. Cydonia is somewhat like Epiblemum, but differs from that genus in that the quadrangle of the eyes is wider behind than in front and occupies one half of the cephalothorax. CYDONIA LUTEOLA, sp. nov. (Plate LXII. figs. 8-8 e.) 3 . Length 3. Length of cephalothorax 1-5 ; width of cephalothorax 1. 2 . Length 3-8. Length of cephalothorax 1-5; width of cephalothorax 1. Legs, 3 $ , 4,1, 3, 2. The first pah- is much the stoutest in both sexes, all the joints excepting the metatarsus and tarsus being thickened. The clypeus is narrow. The falces are only moderately long and stout; in the male they diverge and are directed obliquely forward, the fang being as long as the falx ; in the female they are vertical and parallel with the fang, short. The sternum is oblong. The maxillae are rounded and are less than twice as long as the labium. The abdomen is long in proportion to the cephalothorax and is about twice as long as wide. The cephalothorax is black in the cephalic region, shading into rufous behind; the upper surface is covered with bright yeUow hairs and there is a band of white hairs on each side. The abdomen is light brown covered with silvery down, and on each side is a longitudinal white band. Touching these lateral bands are two pairs of short white bands or spots, the first pair near the middle and the second near the spinnerets. The first leg has the |
