Pardosa iracunda ThorcU, (sub TA'cosa). 



In the pale color of the patella of the male palpus this resembles 

 P. minima Keys., but the palpal organ is quite different and the 

 species is larger. One male and one female. Ft. Collins, Colo. 

 (Baker). One male (Gillette). 



Pardosa atra, sp. nov. 



Leiij;tli 7 mm. Black, witli an indistinct pale central mark on the cephalo- 

 tlioia.x, no lateral marks ; sternum black ; legs black and thickly black-haired, with 

 indistinct pale rings on the tibiix: and metatarsi, coxds with pale spots at base ; 

 abdomen black, with a broad but very obscure pale stripe above ; venter pale on 

 basal half, rest black. The epigynum consists of a red, oval area, with a cavity in 

 the posterior portion, which is much the broader in front, and is divided by a 

 clavate septum, narrower than the space each side. 



One female. West Cliff (Cockerell).

 erect hairs ; sternum constricted between the hind coxrc ; epigynum a blackish lobe,
