NEW PSEUDOSCORPIONIDA. 



BY NATHAN BANKS, EAST FALLS CHURCH, VA. 



In the Canadian Entomologist for 1891, pp. 1 61-166, and 1893, 

 pp. 64-67, I described a number of these small Arachnids, and in the 

 Journ. N. Y. Ent. Soc, 1895, pp. 1-13, I presented a review of the forms 

 then known from North America. Since then many specimens and species 

 have been collected, and in these pages ten of the new forms are charac- 

 terized, and a new genus erected for a form near Garypus. 



Chelifer fuscipes, n. sp. — Cephalothoraxand palpi dark brown, fingers 

 more reddish, dorsum of abdomen brown, with a broad pale median 

 stripe, legs brown, paler at tips of some of the joints. Cephalothorax 

 subtriangular, minutely granulate, with a few short, nearly clavate hairs ; 

 eyes distinct. Palpi with fine short subclavate hairs, except on fingers, 

 hand and outer side of the tibia, which are simple ; trochanters with 

 distinct tubercle behind, femora a little longer than cephalothorax, 

 subpedicellate, largest at middle; tibiae about as long as femur, pedicellate, 

 evenly convex both sides, but a little broader than femur ; hand barely 

 longer than tibiae, about twice as broad as femur, fingers shorter than hand, 

 stout, curved. Dorsal abdominal scuta finely granulate, outer side very 

 distinctly prolonged behind into acute spines. 



Length, 1.8 mm.
