Genae ( Fig. 7B, D View Fig ) and clypeus ( Fig. 7E View Fig ) black. Rostrum ( Fig. 7E View Fig ) dark yellow. Ventral side of eyes ( Fig. 7A–E View Fig ) blackish brown, dorsal side tawny. Antennae ( Fig. 7A–E View Fig ) yellowish, apical part of first segment with dark brown ringlike marking, second segment with black brown stripe oblique from base to center, apical part with dark brown ringlike marking. Pronotum ( Fig. 7A, C View Fig ) bluish green with dark yellow, tricarinate with blackish brown stripe on both side, lateral posterior margin with black brown short oblique spot on both sides. Mesonotum ( Fig. 7A, C View Fig ) dark yellow with turquoise, median carinae with blackish brown stripe on both sides, outer side of lateral carinae each with 2 dark brown stripes, scutellum blackish brown.
