80 PROCEEDINGS OF THE ACADEMY OF [March, 



Misumena placida = Misumessus asperatus Htz. 

 Philodromus vulgaris = P. pernix Blk. 

 Philodromus prselustris 



Immature specimens of P. pernix Blk. 



Philodromus signifer. 



This, I believe, is the same as Ph. expositus of Keyserling (Ph. 

 maculatus Blk.). 

 Philodromus gracilis = Ph. pernix Blk. 

 Philodromus unicolor = P. infuscatus Keys. 

 Philodromus ornatus. 



Unchanged, Emerton has given a description and figures. 



Philodromus placidus. 



Unchanged; related to Ph. ornatus. 



Philodromus minutus. 



In well-marked specimens the legs are lined behind with black, 

 the hind pair on front edge; I think that Ph. brevis Emer. is the male 

 of this species; I have taken P. brevis at Ithaca. 



Philodromus minusculus. 



This closely resembles Ph. ornatus and it is probably that species; 

 but its very much smaller size induced me to describe it; I have 

 no other specimens as small. 

 Philodromus exilis. 



This differs from the other small species of the genus in elongate 

 abdomen; I believe the Ph. bidentatus Emer. is the male of this 

 species. 



Philodromus rufus. 



Unchanged; Emerton gives figures and description under name 

 of P. pictus. 



Philodromus laticeps. 



This immature male is Ph. pernix Blk. 

 Philodromus aureolus. 



These are young specimens; in appearance they agree with Ph. 

 lineatus. Emer., but one cannot be sure without adults. 



LYCOSID./E 

 Lycosa nidicola = L. helluo Walck. 

 Lycosa communis = L. avida Walck. 

 Lycosa nigroventris. 



This is the male of L. frondicola. 



Lycosa similis = L. pratensis Emer.
