NOTHRUtS TAEGIONII. 489 



mammilliform elevations on the dorsum of the cephalo- 

 thorax, these elevations bear the pseudo-stigmata at 

 their outer margins ; between them the dorso-vertex 

 is somewhat depressed, while it is raised between the 

 anterior mammilliform projections. Pseudo-stigmata 

 far apart, slightly raised. Fseudo-stigmatic organs 

 rather long, filiform. Interlamellar hairs shortish, 

 stout, curving forward. Lamellar hairs similar but 

 considerably larger and covered with fine villous pro- 

 cesses (which are found more or less on most of the 

 hairs). Apodemata joined to the sternum. 



Legs of moderate length ; fourth pair slightly passing 

 the hind margin ; thick, gradually diminishing in 

 thickness towards the distal end, but the femora, 

 genuals, and tibiae are slightly concave in lateral out- 

 line, enlarging rather sharply at the distal ends. The 

 genuals and tibise are about of equal lengths, the 

 femora longer ; but the tarsi are the longest joints, as 

 long or longer than the genuals and tibiae together ; 

 they are excavated at the end to allow the stout single 

 claw to fall back. The legs are fringed with thick 

 curved hairs, which are covered with villous projections 

 like the lamellar hairs, or furnished with a thin mem- 

 branous edge ; they mostly arise from small, chitinous 

 apophyses, and in arrangement are about as follows : 

 — four on the outside of each third coxa; three or 

 four on eacli side and one on the top of each femur, 

 and a second row of three or four on the outer side of 

 each first and second femur below the first line ; one 

 on each side of each genual and tibia, near the proxi- 

 mal end ; and three to five on each side of each tarsus ; 

 there is also a row of about four spikes underneath 

 each tarsus. Tactile hairs very small, a few fine hairs 

 on the tarsi, &c. Claws monodactijle. 



Abdomen hollow in the middle, somewhat raised at 

 the margin. Progaster nearly straight, lateral margins 

 curving sUghtly outward so as to be widest not far from 

 the hind margin; kind margin rounded, it bears four 

 large and two small chitinous apophyses, and there
