Specimens have been examined from only the type locality 

 and Atsion, Burlington Co., New Jersey. But one specimen 

 was taken at the latter locality, that on September 2, 1902. 



But little variation is exhibited b}' the series examined, the 

 differences which do exist being wholly, in the intensity of the 

 coloration and the separate or confluent character of the bars 

 on the outer face of the posterior femora {vide supra). 



A Handsome Species of Tachysphex from Arizona. 



(Hymenoptera.) 



By Henry L,. Viereck. 



Tachysphex propinqnns n. sp. 



This beautiful wasp is related to T. ashmeadii Fox, from 

 which it is easih' separated by the very acute pygidial area, 

 the more elaborate silvery ornamentation, color, etc. 



* In some sfjecimens these bars are confluent and inseparable on the 

 external face, but in all the specimens examined the superior and inter- 

 nal faces are distinctly barred. The female type belongs to the form with 

 the form with the external bars confluent.
