space very convex, supra-antennal tubercles very large, angu- 
late externally; frontal ridge strong, feebly notched in the 
middle; labrum with the lateral angles acute, transverse. 
Antenne as long as the head and prothorax together, formed 
like those of &. spinifer. Elytra, across the high shoulders 
slightly wider than the prothorax, sides more arcuate, disk 
more convex, more nearly* quadrate compared with Z. sfcn- 
fer. Abdomen as wide as the elytra, sides straight, parallel, 
carine on the two basal segments more distant, parallel, and 
three-fourths as long as the segment. Legs slender and 
rather long. The @ characters resemble very much those of 
E. spinifer, except that the fourth and fifth segments are 
emarginate posteriorly for their entire width. 
Habitat. South Carolina, Georgia.

flead large, eyes large, tempora as long as the eye, arcu- 
ately convergent, occiput not sinuate nor impressed, frontal 
margin straight, sharp, fovez large, in a line with the middle 
of the eye, connecting sulcus deep, parallel to the sides, 
broader and arcuate behind the frontal margin, inclosed space 
very convex, smooth. Sides, external to the sulcus, some- 
what punctured, lateral frontal tubercles strong. Antenne 
not quite as long the head and prothorax together, first joint 
larger than the second; third to eighth joints much narrower 
than the second, equal in width, gradually more transverse; 
ninth longer, nearly twice as wide, obconical, truncate at the 
base; tenth of the same form, larger; eleventh slightly wider 
than long, annulate near the acute apex. Prothorax widest 
before the middle, where it is arcuately rounded, and slightly 
sinuate anteriorly, sides, toward the base, nearly straight, con- 
vergent; near the lateral fovezee they are imperceptibly sinu- 
ate; the basal angles are rounded; disk convex, minutely 
punctulate, with a small central fovea; basal sulcus one-fourth 
from the base, deeply arcuate, lateral fovee large and deep.
