side there are no definite markings, but the abdomen is usually 

 lighter »n the middle and toward the front, and the posterior 

 coxae are lighter than those in front. The male is darker than the 

 females. The epigynum has a middle and two lateral pits in front, 

 and a rounded lobe directed backward and fitting into a larger 

 depression. (Fig. 21, 2.) The male palpus somewhat resembles that 

 of P. montana, but the process of the tibia is smaller and the point 

 less turned backward. (Fig. 21, 1.) This species is distinct from 

 P. pacifica Bks., with which it has been compared.

Philodromus canadensis, n. sp. 



5 mm. long. Second femur of male 3 mm. Marked in gray 

 (Fig. 22, 3) much like P. vulgaris and like P. bidentatus with which 

 it is sometimes associated, but it does not have the sharp division 

 between the dorsal and ventral colour areas that is usual in vulgaris. 

 It has somewhat shorter legs than bidentatus, especially in the 

 males. The male palpi resemble those of vidgaris, but the outer

process of the tibia is narrower and the under process more tri- 

 angular and with a short truncate tooth at its base, a little curved 

 toward the outer side of the palpus. (Fig. 22, 5.) The tibia is wider 

 in the middle than in vulgaris, and widened more on the inner 

 than on the outer side. (Fig. 22,5.) The epigynum resembles that 

 of vulgaris, but is shorter. (Fig. 22, 4.)
