CHALEPUS. 51 
covered with large, round, foveolate punctures; medial line with a short longitudinal 
groove. KElytra subparallel, slightly increasing in width towards the apex; lateral 
margin finely serrulate; the apical margin dilated, regularly rounded, broadly quadrate- 
emarginate at the sutural angle, more coarsely serrulate than the sides; moderately 
convex, slightly flattened along the suture; each elytron with eight longitudinal rows 
of large, deeply impressed punctures; the second, fourth, and sixth interspaces, together 
with the suture, costate. 
2. Apices of the elytra entire, or only obsoletely sinuate at the sutural angle. 
3. Chalepus semilimbatus. 
Elongatus, angustatus, parallelus, flavus, nitidus; oculorum orbitis, antennis pedibusque (femoribus basi 
exceptis) nigris ; thorace subcylindrico, fortiter punctato, lateribus, pone medium fere rectis, ante medium 
constrictis ; elytris parallelis, apice rotundatis, minute sed distincte serrulatis; utrisque octo-seriato- 
punctatis, stria sexta medio obsoleta; interspatiis alternis costatis; lateribus anguste nigro-eeneo mar- 
ginatis. 
Long. 24 lin. 
Hab. Mexico, Vera Cruz (Sallé). 
Vertex and front impressed with a deep longitudinal fovea; interocular space 
moderately produced. Antenne about one third the length of the body, slightly but 
distinctly thickened towards the apex; joints cylindrical. Thorax transverse; sides 
rounded, nearly straight and parallel behind the middle, thence rounded and converging 
towards the apex, deeply sinuate behind the anterior angle, the latter produced laterally 
into a short, acute tooth; transversely convex, rather deeply excavated in front of the 
scutellum, deeply and rather closely punctured. Elytra subelongate, parallel, obtusely 
rounded at the apex, finely serrulate; each elytron with eight rows of deep punctures, 
the sixth row obsolete on the middle disc; second and fourth interspaces broadly, the 
sixth less strongly, costate; lateral margin narrowly edged with blackish neous. 
4, Chalepus suturalis, 
Anguste oblongus, subtus niger, nitidus; supra rufo-fulvus, minus nitidus; capite nitido elytrorumque linea 
suturali nigro-zneis, scutello antennisque nigris; thorace transverso, rude et crebre punctato, lateribus 
angulatis; elytris oblongis, parallelis, apice rotundatis, utrisque octo-seriato-punctatis, interspatiis alternis 
vix elevatis.

Hab. GuatuMaLa, Duefias (Champion). 
Vertex smooth, front trisulcate ; interocular space slightly produced. Antenne 
nearly half the length of the body, robust, slightly thickened towards the apex ; joints 
cylindrical. Thorax transverse; sides angulate, straight and parallel from the base to 
the middle, thence obliquely converging to the apex, the anterior angle acute; disc 
transversely convex, slightly excavated behind the middle, coarsely rugose-punctate. 
Elytra narrowly oblong; sides parallel, obtusely rounded at the apex; lateral margin
