Prosthesima minima = Zelotes blanda Bks. 

 An immature specimen. 



Poecilochroa bilineata. 



Belongs iii Cesonia. 



Gnaphosa brumahs. 



This is immature and evidently G. conspersa Thor. 



Gnaphosa humilis = Gnaphosa brumalis Thor. 



No1 quite mature. 



Drassus saccatus. 



Now known as D. neglectus Keys. 



Drassus humilis = D. neglectus Keys. 



CLUBIONID^E. 



Thargalia agilis = Castianeira cingulata Koch. 

 Thargalia perplexa = Castianeira longipalpis Htz. 

 Thargalia fallax = Castianeira descripta Htz. 

 Thargalia bivittata. 



Is known as Castianeira cingulata Koch. 



Thargalia crocata. 



Is Castianeira descripta; the true T. crocata is a southern form. 



Clubiona obesa. 



This is C. crassipalpis Keys., but I believe also Hentz's species. 



Clubiona crassipalpis. 



The female whose vulva is figured is C. canadensis Emer. 



Clubiona canadensis. 



These are young of C. obesa Htz. 



Clubiona pygmaea. 



Appears to be the female of C. minuta Emer., this name, however, 

 is preoccupied by Xicolet for a Chilian species. 



Clubiona rubra = C abbottii. 

 Clubiona lenta. 



Related to C. pygmaza, but I think distinct, the head and mandibles 

 are not as dark as in that species; the eye region is broad as in 



C. latifrons Emer. I have seen another specimen from Washington, 



D. C, but do not yet know the male. 



Clubiona americana = C. riparia Koch. 



C. americana given to replace the preoccupied C. ornata Emer. 



Clubiona excepta = C. pallens Htz.
