DAM^US TENUIPES. 421 



appearance of a purple bloom over it. The creature 

 is, however, usually more or less dusted or covered 

 with a whitish powder. 



Texture of cephalothorax dull and roughish, of 

 abdomen smooth, but not polished. 



Shape. — That of the typical species of the genus, 

 the abdomen very globular. 



Cephalothorax considerably less wide than the 

 abdomen, without any true sculpturing, but rising to 

 broad elevations opposite the insertions of the first 

 and second pairs of legs, leaving a strong depression 

 between on each side of the body. The central part 

 of the cephalothorax is considerably raised and arched, 

 but there is a sharp depression before reaching the 

 abdomen, extending the whole width of the body. 

 Rostrum rather small, pyramidal. Two pairs of rostral 

 hairs. The elevation opposite the first pair of legs 

 terminates outwardly in a small projection on each 

 side, between the first and second pairs of legs ; this 

 projection is rounded and without any point anteriorly ; 

 the second coxa is articulated to its posterior edge. 

 There is a smaller projection, with a curved anterior 

 point, behind the insertion of the second pair of legs. 

 Pseudo- stigmata much raised ; near together. Pseudo- 

 stigmatic organs rather short for the genus, ivith rod- 

 like peduncles of even thickness throughout, suddenly 

 increased in thichiess, and continuing the increased 

 diameter until near the point, so that they have the 

 appearance of bearing an elongated cap or pileus ; 

 they stand outward and usually slightly forward. In- 

 ter lamellar hairs short, rough, and rod-like. 



Legs very long and slender, with fine clavate joints. 

 The COX93 of the first two pairs are very small, and the 

 femora of these legs are turned almost at a right angle 

 at their proximal insertion. The coxse of the two 

 hinder pairs much longer, curved, and clavate. There 

 are two large curved hairs on each coxa of the third 

 pair, one or two on the thin proximal part of each 

 femur of the first two pairs, and one whorl on this and
