and generally interrupted at summit, sometimes entirely obsolete; scape sim- 

 ple, aceuminate at base, the apex not reflexed ; disc of metathorax more or less 

 reddish-yellow; wings as in simplex ; legs entirely black, with pale sericeous 

 hairs; abdomen ovate, polished, sanguineous; first segment much as in epicus, 

 the disc with two short oblique depressed lines, or fovese, near apex, diverging 

 towards base; second segment with a flat triangular space on basal middle, 

 bounded laterally by a deep subcrenulated depression, on each basal corner a 

 more or less deep oblique fovea, median transverse line deep, sinuate, simple, 

 not crenulated, a small shallow fovea on each side near apical corner; oviposi- 

 tor of 9 longer than abdomen. Length .20 — .40 inch. 



Twelve specimens. (Belfrage.) Varies much in size. Distinct 

 from simplex by the smaller head, by the scape being simple, and by 

 the different sculpture of the abdomen.

 cubital cell, which is shorter than usual, with its basal nervure very oblique; 

 legs black, with long pale hairs, apex of trochanters tinged with reddish; ab- 

 domen long, narrow, without transverse depressions; first segment subquad- 

 rate, about one-fourth the length of entire abdomen, longitudinally rugose, the 

 intervals confluently punctured, a small polished space on apical middle; re-
