Antenna pale brown, scape and pedicel darker. Mouth parts blackish brown.   
 Thorax. Prothorax blackish brown. Mesonotum brown; anterior surface of scutum blackish brown; anterior margin of lateral lobe of scutum black; posterior part of median lobe white; lateral lobe with paler oval part medially; anterior margin of scutellum blackish brown; postnotum brown. Metanotum brown, with pale oval part on posterior region of each lateral lobe of scutum; medial lobe with white spot medially; anterior margin of scutellum blackish brown.

 Forewing (Fig. 36A). Spots in cell a 1 apparent. Opposing spots in cell r large, almost fused with each other. Proximal band broad in cell CuP but narrower in cell CuA, broadly interrupted just beyond fork of M + Cu, cell CuA including pale spot. Median spots dense, some spots fused with each other, forming larger markings. Distal band faint, broad in cell r 5, fragment of band in cell r 3 small. Spot on roof of cell m 3 small, darker than marginal cloud. Submarginal spots apparent; spots in cell r 1 and r 3 smaller than others. Marginal clouds apparent and dark. Hindwing. Hyaline with faint brown markings in cell CuP; veins brown.
