Common in the Southern States, under pine bark. I have adopted the name 
under which it has been sent me by Dr. Zimmerman. Body subglobose, very 
little longer than wide, rufous, somewhat shining ; head and thorax finely punc- 
tured, the latter not margined at the base. Elytra strongly aciculate, marked 
on Sayh side witha ince curved line, of a parabolic form; the outer leg of this 
curve may be traced quite to the apex, forming a fine marginal line; the epi- 
pleure and under surface of the body are very coarsely punctured. Pygidium 
strongly inflexed, punctured. Anterior tibiew strongly dilated. 
The prosternum is punctured, slightly emarginate behind, and not striate. 
Acritus Lee. 
Prosternum utrinque truncatum, bistriatum ; mandibule retracte ; scrobiculi 
antennales maximi profundi, in thoracis parte inflexa antice siti; antenne funi- 
culo tenui, capitulo ovali; maxille2 mala interiore unco apicali armata; tarsi 
postici quadriarticulati; pygidium perpendiculare. 
Although by Erichson considered as a portion of Abraus, I have ventured to 
separate these species as a distinct genus, since the characters already pointed 
out by Redtenbacher (Fauna Austr. 240) in the form of the posterior tarsi and 
the inner lobe of the maxillz seem to indicate the necessity of removing these 
species from Abreus. 
In the form of the antenne and the cavities for their reception, this genus 
agrees perfectly with Abraeus; the prosternum is, however, less flat, and is 
truncate posteriorly as well as in front; it is marked with a distinct stria on
