Description

For a key to the terms used, see Glossary of entomology terms.

The butterfly, which has a wingspan of 50 to 55 mm, is unmarked dark brown above. It resembles the common banded awl (Hasora chromus), except that it has no white band below; and the apex of the forewing and the disc of the hindwing below are purple washed. The male has apical spots but no brands above. The female has large yellow spots in cell 2 and 3, and apical dots.[4][5]

The Sri Lankan race has no apical spots on the male above and no purple wash below.[4][5]

Edward Yerbury Watson (1891) [6] gives a detailed description, shown below:

Underside brown suffused with purple; forewing with a blackish costal patch before the apex, posterior margin yellowish; hindwing with a subbasal and submarginal suffused blackish band, the latter terminating in a black patch on anal lobe; above the patch is a purple-white streak, and within the cell a small bluish white spot. Palpi and body beneath dull yellow. Legs, pale brown.

Female, above brown suffused with vinaceous yellowish brown basally; forewing with the three small subapical spots (as in male) and three rather large obliquely quadrate spots, two being disposed on the disc, the third above and within the cell. Underside with the spots on forewing as in upperside; hindwing as in male.
