CHALEPUS. 65 
Antenne robust, obsoletely thickened towards the apex, rather longer than the head 
and thorax; joints cylindrical, the first two short, equal, the third scarcely longer than 
the second. Thorax broader than long, sides converging from base to apex, subangulate- 
rotundate ; disc transversely convex, transversely excavated behind the middle, coarsely 
and closely punctured. Elytra broader than the thorax ; sides very slightly dilated, the 
apices regularly rounded, outer margin distinctly serrulate ; each elytron at the extreme 
base and on the hinder disc with ten, on the anterior disc with nine, rows of 
large, deeply impressed punctures; second and fourth interspaces rather strongly and 
equally costate, the eighth interspace less strongly elevated, the sixth interspace 
thickened at its apex, the suture also thickened.

verse; sides angulate, converging from base to apex; disc transversely convex, trans- 
versely excavated behind the middle, closely and coarsely, but not very deeply punctured. 
Elytra broader than the thorax, subparallel, regularly rounded at the apex, the outer 
margin minutely serrulate ; each elytron with ten, just before its middle with eight or 
nine, rows of punctures; the second and fourth interspaces costate, the eighth less 
strongly elevated.

nigro-piceis, pedibus nigris, femoribus (apice excepto) piceo-fulvis; supra opacus, capite (vertice excepto) 
nigro; thorace conico, lateribus fere rectis, medio obsolete angulatis, anguste nigro marginatis; disco 
subcylindrico, pone medium transversim excavato, crebre rugoso-punctato ; elytris parallelis, apice rotun- 
datis, lateribus minute serrulatis, margine apicali paullo dilatato, acute denticulato ; utrisque decem-
