COLORATION. Vertex, pronotum and mesonotum (Fig. 17A–D) bluish-yellow. Middle carinae of vertex with blackish brown striped spot on both sides. Lateral border areas of pronotum and mesonotum slightly dark brown. Frons (Fig. 17E) brown-blue. Apical part of frons, clypeus (Fig. 17E) and genae (Fig. 17B, D) black. Antennae (Fig. 17A–E) yellowish brown, circular spot at apex of first segment, second segment with oblique spot from base to middle, circular spot at apex dark brown. Forewings (Fig. 17F) dark brown, apex of apical and postcostal cells with 5–6 different-sized transparent spots, inner side of crossveins with 3 dark brown burl spots, middle part big.

Frons (Figs 17E, 18B) elliptic, widest in the middle, base narrower than end, longer in middle line than wide at widest part (2.0:1), with obvious median carinae. Antennae (Figs 17E, 18B) with first segment shorter than second segment about 1:2.0. Pronotum (Figs 17C, 18A) same length as vertex.
