CHALEPUS. 77 
Front trisulcate; interocular space rather strongly produced, obtuse. Antenne 
-subfiliform, equal in length to the head and thorax; third joint one half longer than 
the second. Thorax transverse; sides converging from base to apex, bisinuate, the 
anterior angle acute, the basal one obtuse; disc transversely convex, closely covered 
with large irregular punctures. Scutellum transverse, its apex truncate. Elytra 
narrowly oblong, parallel, the apices conjointly and regularly rounded, the lateral margin 
obsoletely, the apical one distinctly, serrulate; convex, slightly flattened along the 
suture; each elytron with ten regular rows of punctures, the interstices thickened, 
elevate-reticulate ; second and fourth interspaces moderately, the eighth less distinctly, 
-costate; the humeral fulvous patch, covering the humeral callus, commences at the 
basal margin and runs downwards for about one third the length of the elytron, but 
does not extend to the lateral margin.

Hab. Nicaraeua, Chontales (Belt). 
Face strongly produced between the eyes; vertex and front opaque. Antenne half 
the length of the body, robust, rigid, very slightly compressed ; two lower joints short, 
cylindrica], the basal one submoniliform, the second turbinate, the third and fourth 
equal, each nearly as long as the preceding two united, apical joint acute. Thorax 
transverse; sides slightly rounded, converging from base to apex, in some specimens 
obsoletely angulate just before the middle; upper surface transversely excavated on 
the hinder disc, opaque, impressed, but not very closely, with large shallow punctures ; 
the lateral margin, together with a discoidal vitta, sometimes abbreviated anteriorly, 
black. Elytra broader than the thorax; sides gradually dilated from the base towards 
the apex, the apex itself regularly rounded ; lateral margin distinctly serrulate, apical 
margin armed with several short, acute_spines ; each elytron with ten regular rows of 
large deep punctures, the second and third Jnterspaces rather strongly costate ; a short 
sutural vitta at the base, together with a large apical patch, covering rather more than 
the hinder third of the disc, black.
