tary, no tubercle beneath stigma; mesosternal tubercle flat, indistinct; 

 longer spur of hind tibiaB equal to about one-quarter of the length of first 

 hind tarsal joint; abdomen ovate, apically clothed with long, black hairs, 

 first segment rounded anteriorly, impression of second ventral strong, 

 before middle. Length 23 mm. 



Texas. One specimen. Distinguished by its small size, and 

 by the wings not being heavily margined with black, the red 

 dish yellow appearing to gradually coalesce with the subfuscous 

 of apical portion of wings. In this respect it is allied to the 

 tropical species, P. lurida, periphetes and nigricans. Dedi 

 cated to Herr Robert Lucas, whose skill and energy have pro 

 duced, a remarkable work, a monograph of the genus Pepsis, 

 which will stand as a classic in entomological literature.

 surfaces less distinctly marked than usual, through the small median, 

 transverse fold (sometimes absent) ; horizontal surface broadly furrowed

 on to the sides, the usual longitudinal furrows or depression not distinct, 

 posterior surface also transversely rugose, lateral teeth absent or rudimen
