CHALEPUS. | 79 
outer joints closely articulated, the apical one very acute. Thorax transverse, sub- 
conic; sides obliquely converging from base to apex, bisinuate ; subcylindrical, trans- 
versely excavated on the hinder disc, torulose at the base on either side; opaque, 
irregularly punctured. Elytra narrowly oblong, parallel, finely and subremotely 
serrulate on the sides; apex conjointly rounded, coarsely denticulate, and armed on 
either side with two or three large teeth or spines; each elytron with ten regular rows 
of punctures, their interstices elevate-reticulate; the second and fourth interspaces 
rather strongly, the eighth moderately, costate, the sixth also costate at base and apex.

Hab. Mexico (Sallé).—Co tomsia, Santa Marta. 
Very closely allied to the preceding species; the thorax more coarsely and closely 
punctured, the apex of the elytra more obtuse, the five outer joints of the antenne 
more loosely articulated, the apical one less acute. I have only seen two specimens of 
this species—one from Mexico, without precise locality, the other from Colombia; in 
the Mexican specimen the hinder femora are entirely black, whilst in the Colombian 
one the sides of the thorax are less distinctly angulate. 
VI. Elytra each with ten rows of punctures, the base with a short additional row 
next the suture.
