while the thoracic falls very slightly in the first third, and then 

 abruptly. The sides are vertical and nearly parallel, there being 

 a Aery slight widening behind the dorsal eyes. The anterior eyes 

 are close together in a straight row. They are large, the lateral 

 being two-thirds the size of the middle. The second row is about 

 halfway between the first and the third, and the third is about as 

 wide as the cephalothorax. The quadrangle of the eyes is one- 

 fourth wider than long, occupies one-half of the cephalothorax, 

 and is equally wide in front and behind. 



In the male, the cephalothorax is covered with red hairs, 

 excepting bands of white hairs on the lower sides, and a white 

 median band on the thoracic slope, running backward from the 

 third row of eyes. On the abdomen the hairs are golden-yellow ; 

 down the middle, in the anterior half, is a narrow white band, 

 which changes, in the posterior half, into a band of white chevrons. 

 A narrow white band runs around the anterior end and onto the 

 sides, curving upward and inward opposite the point at which 

 the chevrons begin. The legs are pale, with the femur dark in 

 some specimens. The palpus has the patella much elongated, 

 nearly equalling the tibia and tarsus. The patella and tibia 

 are flattened and rugose on the dorsal surface, and there is an 

 apophysis on the inner distal end of the patella. There is a 

 fringe of white hairs throughout the whole length of the palpus, 

 on the inner side. The falces are as wide as the middle eyes 

 and are transversely rugose. In the middle, on the outer edge, 

 is a small apophysis which is edged with minute notches, and 

 below this, near the insertion of the fang, there is a longer, 

 pointed apophysis. The lip is narrow, and only half as long as 

 the maxillae, which are notched on the middle of the outer edge 

 and project at the outer corner. The female has golden-yellow 

 hairs on the cephalic plate, and has the eyes on dark spots. 

 There are indistinct bands of a lighter colour on the sides and 

 down the median line of the thoracic part. On the abdomen the 

 hairs are red, and there is a yellowish band which passes around 

 the front end onto the sides, from which a short projection runs 

 backward in the middle line. On the middle dorsum there is a 

 white region with wavy outlines, which is mottled with red. 



"We have numerous examples of both sexes. 



Cybele albopalpis, n. sp. (Plate II. tigs. 3-3 b.) 



J. Length 5*5 mm. Legs 134 2, the first plainly stoutest, 

 and longer than the second by the tarsus and half the metatarsus. 



The cephalothorax is rather high, and slants in both directions 

 from the dorsal eyes, the hinder slope being almost continuous. 

 The anterior eyes are large, and form a slightly curved row, the 

 middle ones touching, and the lateral a little separated from them. 

 The middle are less than twice as large as the lateral. The second 

 row is about halfway between the first and the third. The dorsal 

 eyes are large, and form a row which is as wide as the cephalo-
