Chelifer scabrisculus Si//io/i. — Ann. Soc. Ent. Fr., 1878. 

 Ch. litgeinraliis B.M.ZAX, .\nn. Soc. Ent. Fr., iSgi. 



Described from Southern California; I have it from S. Calif, 

 one specimen (Cooper Curtice); Lake Tahoe, Calif., one specimen 

 (Hubbard); Hood's River, Oreg., one specimen (Hubbard); and 

 two specimens under stones, Utah Lake, Utah, (Hubbard), are 

 reddish and have slightly longer fingers, but are hardly different. 



Chelifer mirabilis, sp. nov. 



Length, 2.6 mm. Cephalothorax and palpi red-brown; abdomen and legs 

 brownish. Cephalothorax rounded, and slightly narrowed near anterior margin; 

 no eyes; sutures distinct; surface finely granulate, no larger granules. Abdomen 

 quite broad, about twice as long as the cephalothorax. Palpi slender; trochanter 

 pedicellate, tubercled above near tip; femur slightly longer than cephalothorax, 

 gradually enlarged from base to near tip, inner margin straight, outer slightly 

 convex; tibia three-fourths as long, and slightly broader than femur, quite long 

 pedicellate, outer margin slightly and evenly convex; inner margin convex at base, 

 then nearly straight; hand about as long as tibia, slightly convex on outer margin, 

 quite strongly and evenly on the inner margin, tapering to the fingers, which are 

 about as long as the hand and quite strongly curved. Short clavate hairs on whole 

 of palpi except fingers; similar ones on rest of body. 



Three specimens, Indian Cave, Barren Co., Ky., June, (H. G. 

 Hubbard); two specimens. Cave at Pennington Gap, Va., (H. G. 

 Hubbard). A very peculiar species, particularly on account of the 

 form of the tibia of the palpus, which is quite unlike that of our 

 other species, but somewhat like the European C. latreillii. 



Chelanops N'icolct. 



Tomosvary in 1882 (Pseudosc. faun. Hungar.) divided this 

 genus into Lainpror/icnics (those with long and simple hairs on 

 the palpi) and TracJiychenies (those with short, thick hairs). 

 Nearly all of our forms belong in the latter group. The species 

 from the United States I would arrange in the following way : 



f^ Hairs on the palpi very long and simple, abdomen long and of 



! equal width throughout {Lai/iprochentes) oblongUS, groSSUS. 



I Hairs on the palpi short and thick often clavate, abdomen 



much the widest in the middle {Trachychcrucs) i 



( Hand with a projection on inner side deiltatUS. 



/ Hand without any projection 3 



\ Fingers as long or nearly as long as hand 4 



i Fingers much shorter than hand 1 1 



\ Hairs not distinctly clavate 5
