prothorax obviously elongate, much wider than the head, the sides 
parallel and straight, the basal angles rather more rounded than the 
apical, the punctures fine, very sparse, larger and more close-set in the 
unimpressed series limiting the medial smooth space; elytra elongate, 
a fourth to fifth wider and a third to fourth longer than the prothorax, 
subparallel at the sides, the punctures fine and not close-set, arranged 
in unimpressed series; abdomen distinctly narrower than the elytra, 
densely punctulate and dull. Male with avery small, extremely shallow 
sinus at the middle of the apex of the fifth ventral, the sixth strongly 
impressed along the middle, the impression rather abruptly limited 
laterally, gradually narrowing from the apex and disappearing near basal 
fourth, the apex with a large deep and abruptly formed triangular notch, 
two-fifths as wide as the apex and fully one-half deeper than wide, with 
its angle narrowly rounded, the notch wholly within the impression, 
which extends narrowing along its sides to the apex, the apical lobes 
narrowly rounded; female with the sixth ventral obtusely rounded at 
tip. Length 4.5 mm.; width 0.75 mm. Mississippi (Vicksburg).
