impressed on the sides and at the base with large round punctures; anterior disc nearly 
impunctate. Elytra broader than the thorax, parallel on the sides; lateral margin 
entire, the apical margin rounded, emarginate at the suture, finely serrulate ; cylindrical, 
slightly flattened along the suture ; each elytron with eight, at the base with nine, rows 
of deeply impressed large round punctures; second, fourth, and sixth interspaces 
costate.

Vertex smooth, impunctate ; front trisulcate ; third joint of the antenne longer than 
the second, five upper joints slightly thickened. Thorax distinctly longer than broad ; 
sides obtusely rounded ; subcylindiical, transversely depressed on the hinder disc ; deeply 
and closely punctured, the punctures larger and stronger on the middle ; a space imme- 
diately behind the anterior margin nearly free from punctures. Elytra broader than 
the thorax, parallel on the sides, regularly rounded at the apex, apical margin minutely 
serrulate; upper surface subcylindrical; each elytron with eight, at the extreme base 
with nine, rows of deeply impressed punctures; the suture, together with the second, 
fourth, and sixth interspaces, costate. Mesofemora with a distinct row of teeth beneath. 
The present species may (according to Dr. Horn) be known from C. nigrita, Oliv., by 
the relatively greater length of the third joint of its antenne, by its larger size, by the 
different coloration of the upper surface of the body, and lastly by the stronger teeth on 
the under surface of the mesofemora ; from C. funesta it is separated by the presence of 
these teeth, by the different punctuation of its thorax, and by its strong metallic tint.

PARACHALEPUS. 
Caput inter oculos valde productum ; antennis 10-articulatis ; ore ut in Chalepo. Corpus elongatum. 
The above genus agrees with Chalepus in all essential characters with one exception— 
the antenne are ten- instead of eleven-jointed. I only know a single species, P. brevi- 
cornis from Mexico, and of that only a single specimen.
