174 Mr. J. Blackwall on neivhj discovered species of Avaneidea. 



ruptly sloped behind, depressed and prominent before, projecting 

 beyond the base of the falees ; it is of a fulvous colour, with the 

 entire space between the eyes, a line extending along the middle 

 of its posterior half, several oblique ones on the sides of that 

 part, and the margins of a black hue, the cephalic region having 

 a slight tinge of brown, and the anterior eyes are surrounded 

 with white hairs. The falees are small, conical, vertical, and 

 have a few minute teeth on their inner surface; the maxillae, 

 which are straight, are enlarged and rounded at the extremity ; 

 the lip is moderately long and rounded at the apex; and the ■ 

 sternum has a regular oval form. The colour of these parts is 

 pale yellowish brown, the sternum having a broad black border. 

 The legs are robust, particularly those of the anterior pair, and 

 are provided with hairs and sessile spines, two parallel rows of 

 the latter occurring on the inferior surface of the tibiae and me- 

 tatarsi of the anterior legs ; the fourth pair is the longest, the 

 first pair rather surpasses the third, and the second pair is the 

 shortest; their colour is pale yellowish brown, and there is an q 

 irregular black spot on the upper part of the coxa; of the posterior- 

 pair, and a curved one at the extremity of the femora of the ! 

 anterior pair, on the under side; each tarsus is terminated by 

 two curved, slightly pectinated claws, below which there is a 

 small scopula. The palpi resemble the legs in colour, and have 

 a few black spots on the cubital, radial, and digital joints, in 

 front. The abdomen is oviform, convex above, projecting a little 

 over the base of the cephalo-thorax ; it is clothed with black and 

 short hoary hairs, and is of a fulvous colour, with curved, trans- 

 verse, oblique rows of black spots, more or less confluent, 

 extending from the upper part to the sides ; and on the under 

 part numerous black spots are distributed without regularity ; 

 the branchial opercula have a pale yellowish tint ; and there is a 

 longitudinal black streak on the upper part of each superior 

 spinner. 



In October 1853 an immature female of this species, which is 

 nearly allied to Salticus frontalis and Salticus reticulatus, w^as 

 received from the Rev. Hamlet Clark, who took it near North- 

 ampton in the autumn of the same year.

The legs are robust, especially those of the first and second 

 paii's, and are provided with hairs and strong black spines ; their
