Helluomorphoides nigripennis

Diagnosis
The relatively small eyes, blue-black elytra with narrow, biseriately punctured striae, will serve readily to distinguish this species from all other known North American helluonines. The shape, and relatively large size of the pronotum, and the shape of the maxillary palpi are also of diagnostic value.

Distribution
Lindroth (1955: 25) reports that no example of this species in the Oberthiir Collection is marked as a Dejean type. No type locality other than "Amerique septentrionale" was indicated in the original description. The type specimen was sent to Dejean by Le Conte, and was therefore probably collected in southern Georgia, or southern New Jersey. This species appears to be confined to the Atlantic and Gulf coastal plain and piedmont, ranging eastward to Georgia from Texas, and northward as far as Massachusetts. It has not been reported from Florida. Life zones : Lower and Upper Austral.
