SOME SYNONYMS IN NORTH AMERICAN LYCOSID^E. 



BY RALPH V. CHAMBERLIN, PROVO, UTAH. 



Pardosa diffusa, Emerton (Trans. Conn. Acad., 1909, p. 208), = 

 Pardosa moesta, Banks (Proc. Acad. Sci., Phil., 1892, p. 70). 



Pardosa tristis, Keyserling (Verh. d. z. b. Ges. Wien, 18S7, p. 485), 

 = Pardosa xerampelina, Keyserling (Verh. d. z. b. Ges. Wien, 1876, p. 

 622). 



Pardosa atromedia, Banks (Proc. Cal. Acad. Sci., 1904, p. 355), = 

 Pardosa lapidicina, Emerton (Trans. Conn. Acad. Sci., 1885, p. 355). 

 This is a common species in Southern California, where the habitat is 

 closely similar to that of the species in the north-east. The agreement of 

 eastern and western specimens in structure and habit is complete. 



Lycosa crassipalpis, Emerton (Trans. Conn. Acad. Sci., 1909, p. 206), 

 is clearly a Sc/iizocosa. It is very close to saltatrix, Hentz, from which 

 its differences are likely to prove less than specific, variation in saltatrix 

 being large. 



Lycosa contest at a, Montgomery (Proc. Acad. Sci., Phil., 1903), = 

 Lycosa pratetisis, Emerton (Trans. Conn. Acad. Sci., 1885, p. 483). 



Lycosa arenicola, Scudder (Psyche, 1877), is preoccupied, and hence 

 must give way to Lycosa Pikei, Marx. 



Lycosa pacifica, Banks (Proc. Cal. Acad. Sci., 1904, p. 354), = Lycosa 

 erratica, Hentz. Examination of extensive material from Utah to 

 California, in comparison with material from the middle west and the east, 

 shows no good basis for the specific or varietal separation of the western 

 specimens. Variations in some points of the characteristic colour pattern 

 are interesting, but wholly in line with the tendencies shown in various 

 other groups in the same regions. 



Allocosa degesta, Chamberlin (Can. Ent., 1904, p. 287), is doubtless 

 the same as Trochosa noctuabunda, Montgomery (Proc. Acad. Sci., Phil., 

 1904). It is a typical Allocosa. 



Lycosa exa/bida, Becker, doubtfully listed in my Revision under 

 Allocosa, was included in the N. A. spider fauna through an error, and 

 should be stricken from our list. It is a South American species. 



Mailed October 13th, 1909.
