as the body, black, the two lower joints stained with fulvous, 
the third joint much longer than the fourth; thorax twice as 
broad as long, the sides forming a distinct angle near the 
middle, from there to the base they are somewhat concave, the 
anterior angles tuberculiform ; surface with a deep longitudinal 
depression from the base to the apex, widened at either place, 
at the sides a deep transverse fovea is placed; scutellum black ; 
elytra bright metallic green at the sides, cupreous at the disc, 
closely and distinctly punctured; the shoulders are very pro-
