Apparently nearest to P. inodcstus Banks, described from New 

 Mexico ; but it is a much larger species differing as well in the charac- 

 ters of the eyes (r. g. the posterior row recurved instead of procurved), 

 in proportions and structure of the male palpus, in the more numerous 

 spines on tibia of leg I, etc. The two species are alike in their dark 

 color and in the characteristic roughening of carapace and of dorsum 

 of abdomen. 



Lechrictenus,^ gen. nov. 



Eye-area wider than long, more than L5 times so. Anterior row 

 of eyes strongly procurved; median and lateral eyes subequal. Poste- 

 rior median eyes somewhat larger than the laterals. 



Rastellum extending as a narrow band wholly across chelicera; 

 not at all extending proximad along mesal edge; chelicera not in the 

 least prominent at distal end within. 



Labium attenuated distad; armed distally with spinules arranged 

 in several series. 



Spinules on coxae of maxillipedes confined to an area on proximal 

 half. 



Sternal foveolae not far apart; (in type there is in addition a deep 

 transverse furrow tangent to anterior edges of foveolae). 



Tibiae, metatarsi, and tarsi of four anterior legs and tarsi and tibiae 

 of palpi with a longitudinal band of spinules on each side. Meta- 

 tarsus and tibia of leg III spinulose above at distal end only. Tarsi 

 of legs III and IV pluriaculeate near claws. 



Type Species. — Lechrictenus lamprus, sp. nov. 



This genus differs from Pachylomerus, which it in general resembles, 

 in having (1) the anterior median eyes subequal to the laterals as in 

 Conothele; (2) the metatarsus III aculeate only at distal end, also 

 much as in the latter genus; (3) the spinules on coxae of pedipalps 

 confined to proximal half; and (4) conspicuously in the form of the 

 rastellum. The eye-area is narrower proportionately than in the 

 Asiatic genus Conothele, the anterior row is more strongly procurved, 

 the posterior median eyes are relatively larger, etc.
