Head with an eneous tinge ; vertex trisulcate, the lateral grooves deeply impressed ; 
apex of the clypeus produced into a transverse bifid plate. Antenne rather more than 
half the length of the body; first and second joints short, subnodose, the rest of the 
joints compressed, the third to the seventh cristate; the joints from the eighth to the 
apical one gradually decreasing in width. Thorax transverse, subconic ; sides con- 
verging from the base to the apex, slightly bisinuate ; transversely convex, flattened 
and excavated on the hinder disc, coarsely punctured; a broad bicallose impunctate 
vitta on either side fulvous. Elytra gradually increasing in width towards the apex ; 
sides finely serrulate ; apical margin dilated, more strongly serrate, broadly subquadrate- 
emarginate at the sutural angle; each elytron with eight regular rows of punctures, 
the second interspace strongly costate. 
The three types of coloration of the elytra which I have indicated appear to be 
fairly constant, intermediate forms rarely occurring in a long series of specimens. 
In this species the four upper joints of the antenne, although closely amalgamated, 
are indicated by notches on the upper margin of the club; this probably misled 
Dr. Chapuis, and caused him to Place the ‘Species in -Chalepus.
