Elongate, subparallel, moderately convex. Head impressed between 

 the eyes with a large triangular fovea; antennsie filiform, two-thirds 

 the length of the body. Thorax about a third broader at the base than 

 long, narrowed from base to apex, apical margin concave, sides straight, 

 obliquely narrowed at the apex ; above smooth and shining, middle 

 of disk with a faint longitudinal line; along and just within the outer 

 border are placed a number of deep irregular excavations, the surfaces 

 of which are deeply punctured; the gi-een colour of the disk varies 

 greatly in extent in different individuals, in some covering nearly the

 base of the thorax, sides subparallel, apex subacutely rounded ; surface 

 of each elytron impressed with eleven rows of punctures, the first 

 abbreviated ; on the basal half the striae are well marked and deeply 

 pimctured, on the apical half they become faint, confused, and nearly 

 obsolete.
