NOTES ON NORTH AMERICAN LYCOSID.^. 



BY RALPH V. CHAMBERLIN, PROVO, UTAH, 



From the list of North American Lycosidfe given by the author in his 

 recent Revision, some names that he had placed in synonymy were inad- 

 vertently omitted. These are listed below, together with supplementary 

 notes upon a few other forms, and some comments of more general 

 character. A few species of Walckenjer, TuUgren and others are reserved 

 for discussion as to synonymy in a subsequent article. 



Pirata procursus, Montgomery (Proc. Acad. Sci., Phil., 1902, p. 

 583) = Pardosa xerainpciina, Keyserling (Verh. r. b. Oes. W'ien., 1876, 

 p. 622). 



This synonymy was noted in the Revision under P. xeranipelina, but 

 was omitted from the general list given in the early part of the work. 



Pardosa solivaga, Montgomery (Proc. Acad. Sci., Phil., 1902, p. 574) 

 ^ Schizocosa ocreata, Hentz (J. Bost. Soc. Nat. Hist., 1844, p. 391). 



Like the preceding, noted previously in the Revision under the 

 species, but omitted from the list. 



Lycosa nidi/cx, Marx (American Naturalist, iS8r, p. 396). The 

 author placed this previously as a synonym of Pt'kci (arenicola) upon the 

 authority of Banks, who presumably had access to Mar.v's types. Mr. 

 Banks informs me that he now regards the species as distinct, a view 

 which I can confirm fully from a study of a pair of individuals apparently 

 representing it, and kindly sent me for identification from the American 

 Museum of Natural History by Dr. A. Petrunkevitch. The form was not 

 previously known to me at first hand. The copulatory organs present 

 definable differences from those of Ptkei, and more decided ones from 

 those of fatifera, with which it also has affinities of a close kind. A 

 description of the form, with figures of epigynum and palpal organ, follows : 



Female. — Integument of cephalothorax dark reddish-brown without 

 definite light markings, but the median dorsal portion of pars cephalica 

 and the clypeus paler ; the hair in specimens described mostly rubbed off. 

 Chelicerse reddish-brown, like the cephalothorax, densely clothed with 

 rusty-yellow hair with intermixed darker bristles. Labium and endites 

 brown, both paler distally. Sternum and coxae of legs beneath light 

 yellowish-brown, clothed with light hair. Legs light yellowish-brown, 

 entirely without darker markings, excepting that the ventral surface of 

 anterior tibice, tarsi and metatarsi are darkened \ densely clothed with 

 gray hair with numerous longer dark coloured bristles, especially on joints
