Description: body: compact-ovate, slender. Ventral faces: dark brown, all appendages pale yellow. Dorsal: head has pale yellow marking directly above the clypeus which takes up the entire surface between the eyes. The rest of the dorsal face of the head should be iridescent green, punctate. Head broad, short face; labrum pale yellow, nearly white, small dark circle in centre. Minor wrinkles around the eyes, small fovea around the occiput. Pronotum: heavily punctate near the margins, margins not upturned, centre of pronotal disk iridescent green, generally smooth, on the left and right edges of the green mark are wide 'C' shaped macules, both pale yellow. Elytra: about 14 well-defined striae per elytron, in some specimens the striae are fused in random places, each striation lined with numerous, closely-spaced fovea. Sutural margin bright green, with two sets of blotchy maculations branching off of them near the centre of the suture, and close to the elytral apex; these often give the appearance of a pair of eyes and a grinning mouth. Each humeral shoulder sports an individual blotch-macule, with three points aiming towards the elytral apex. Below these one should find another blotch-macule near the centre of the lateral margin, again, below these further on-nearer to the apex-should be one small 'v' shaped macule on each elytron. Each macule's point is aimed towards the elytral apex.
