 entire tarsus, which have a brownish-yellow colour ; the fourth 

 pair resembles the first in colour, the coxa and exinguinal joint 

 excepted, which are of a brownish-yellow hue, with a few soot- 

 coloured marks ; and the second and third pairs difi"er from the 

 fourth pair in having the femur, tibia, and metatarsus marked 

 with brownish yellow. The palpi are of a brownish-yellow hue, 

 that of the base of the humeral joint being brownish black ; the 

 digital joint of all the specimens examined was of an elongated 

 oval form, and very tumid, indicating that they had to undergo 

 their final ecdysis before they became adult. The abdomen is 

 of an oblong-oviform figure, convex above, glossy, and of a black 

 hue, the under part being the palest ; the anterior region of the 

 upper part is sparingly clothed with white hairs, and a short, 

 transverse, curved bar, consisting of white hairs, and having its 

 convexity directed forwards, occurs in the posterior region, a 

 little above the coccyx, which has a few white hairs distributed 

 upon it ; the colour of the branchial opercula is brown, and that 

 of the spinners brownish yellow. 



Three immature males of this species, captured in the vicinity 

 of Lisbon, were presented to me by the Rev. Hamlet Clark.

The eyes are seated on black spots on the anterior part of the 

 cephalothorax ; the four intermediate ones form a trapezoid, 

 the two anterior ones, constituting its shortest side, being the 

 smallest of the eight ; the eyes of each lateral pair are placed 

 obliquely on a tubercle, and are almost in contact. The cephalo- 

 thorax is slightly compressed before, rounded on the sides, 

 convex, glossy, and has an indentation in the medial line ; it is 

 of a yellowish-brown colour, the sides and a spot at the posterior 

 point of the cephalic region having a brown hue. The falces 

 are long, conical, somewhat divei'gent at the extremity, inclined 

 towards the sternum, and armed with teeth on the inner surface; 

 they are of a pale reddish-brown colour, with an obscure brownish 

 streak passing from their base, on the inner side, obliquely out-
