One specimen. Georgia. Tlic stria* of the elytra arc well impressed; it resembles in 

 appearance a small specimen of Dicrepidius soleatus, but is at once known by its finely 

 punctured thorax.

I have modified the diagnosis of this genus, as given by Germar, to allow the introduc- 

 tion of several species, which seem t.p differ from the type only in the absence of the two 

 acute perpendicular ridges which run from tli«' margin of the front to the hase <>f the In- 

 brum, and limit the fovea in which the antennm are inserted. From the two preceding 

 genera, this differs in the form of the lamina' <>f the post< rior coxa', w huh arc i marginate, 

 or sinuate posteriorly, as in Elater. The posterior angles <>l the thorax an- long ami 

 Bharp, the carina is well defined and almost parallel with the margin; the basal fissures 



are short ami distinct.

Southern Stat j, rare; more abundanl in Cuba and South America. In the mile the 

 third ami follow m_ r pint- of the antennae are furnished w ith a Biibapical, elongate, spatulate 

 process; the eleventh joint extends beyond the branch of the tenth punt: in the female 

 the joints are triangular, growing gradual!} narrower, with the last punt one-half l< i 



than the tenth.
