fairly well, but as no structural details are mentioned in the 
description it can only be suggested as possible that the two 
are the same.

The female of this species was not known at the time that 
the male was described. Mr. H. B. Parks of San Antonio, 
Texas, has since collected it in numbers and the following 
description is based on that material. 
Female: — Size: Length, 13-15 mm.; breadth of abdo- 
men, 4.5-5 mm.; anterior wing, 10-11 mm. 
Structure: Facial quadrangle about as broad as long; 
eyes subparallel ; facial protuberance broad, evenly in- 
curved, the lateral angles conspicuous ; clypeus with shining 
impunctate apical margin which has a small median emargi- 
nation and a slightly deeper emargination on each side of 
the middle; a shining malar space evident, this separated 
below from cheeks by a quite deep concavity; mandibles 
obtusely 3-dentate, with a triangular punctate basal area 
delimited by deep sutures; all the tibiae with prominent 
spine-like tubercles, largely confined to a single row on the 
front pair, but covering the posterior center surfaces of the 
others. 
Puncturation : Punctures sparse and scattered on the 
relatively dull clypeus, close and rather fine at sides of face, 
on vertex back of ocelli, and most of cheeks, more coarse 
and scattered on cheeks below, more widely separated just 
above eyes ; mesonotum and scutellum rather finely rugoso- 
punctate, the pleura finely and closely punctate above, 
becoming more coarse and sparse below, the propodeum 
tessellate, but hardly punctate, the tegulae impunctate and 
dull ; abdomen impunctate basally, becoming distinctly 
punctate laterally and apically, the punctures of segment 5 
quite deep and conspicuous, quite widely separated medially 
but close laterally. 
Color: Black ; antennae and tegulae very slightly reddened ; 
wings faintly smoky, the nervures piceous to blackish ; spurs 
brownish-yellow.
