 half Avider than long, fifth and seventh scarcely enlarged. Prothorax short and 

 transverse, three-fourths wider than long, gradually and only slightly nar- 

 rowed in apical half, the basal angles acute and everted; apex transversely 

 truncate, anteriorly oblique at the sides, the apical angles anteriorly promi- 

 nent but rather blunt; disk smooth and polished, finely and sparselj' punctate 

 throughout. Elytra short, scarcely more than one-third longer than wide, 

 fully two-fifths wider than the prothorax, parallel and straight at the sides, the 

 apex extremely Ijroadlj- and obtusely ])ut evenly rounded; side margins some- 

 what reflexed, the vertical flanks impressed ; humeri slightly tumid ; disk finely, 

 evenly and moderately closely punctate, Ahdotnen finely and closely punctu- 

 late, the legs somewhat stout; hind tarsi distinctly shorter than the ti])iie.

The only known specimen of this species is likewise a female, 

 and is from an unrecorded part of the State. The species is re- 

 markabl}^ distinct in the prominent apical and acutel}' everted 

 basal angles of the prothorax, and in the verj- short broad form 

 of the bod3\ The epipleura? are not much wider than in the or- 

 dinary- species of the genus, and are gradually narrowed behind, 

 but they are nevertheless somewhat intermediate between the 

 usual type and the broad horizontal form characterizing the 

 genus Eudas3-tes.
