same localities, having the same abdominal markings, agree well with 

 Peckham's description of/*, dolosus. 



Pellenes ccecatum Hentz. 



Females taken on the same spot with males and evidently the same 

 species agrees with Peckham's description of P. sabulosus. I have 

 seen males and females from various localities between Long Island, 

 N. Y., and Brazos Co.. Texas. In some males the apical apophysis 

 of patella III is a little longer than in others, but palpus and markings 

 are the same. 



Pellenes birgei Peckham. 



Males from Canon City, Colorado, agree with the description. 

 They have the tibise and patellae III and IV dark on sides and have a 

 narrow dark line above. Females from the same locality and marked 

 like males, have the clypeal marks and other characters of P. politus 

 Peckham, which is based on a female.
