 male clasper obliquely rounded off from below. 



The general coloration is black, with the legs mostly or entirely 

 fulvous, and usually with a broad whitish border on the interantennal 

 process. Details of coloration vary between the three subspecies, as 

 described below:

Coxae and trochanters fulvous, the coxae sometimes more or less blackish . 2 



2. Front and middle coxae of male yellowish fulvous beneath; interantennal 



process of face broadly bordered with white; range: Transcontinental in 

 Canadian and Transition zones, except California. 



24b. nigripalpis tectulum, new subspecies 



Front and middle coxae of male fulvo-ferruginous beneath; interantennal 



process of face very narrowly bordered with white, or entirely black; range: 



California 24c. nigripalpis subobscurus, new subspecies
