Pronotum uniformly ocher to brownish yellow, fore margin with distinctly black patch behind each eye, posterior margin slightly brighter, first plural sclerite in lateral aspect distinctly rounded with black spots. Scutellum generally pale ocher to pale yellow, usually brighter than pronotum, distinctly large, as large as pronotum, with large black scutellar spots.
