The male has
the forewing and hindwing a very dark brown, but with the patterning typical of
the genus present on the former. The female resembles both sexes of the next two
species but the forewing is duller, with the triangular tornal area more
extensive, extending further basad on the dorsum and being more clearly defined
there. The reniform is much larger in B. labi.
is bilateral asymmetry of the harpe in the male genitalia. In ssp. nigridia Hampson
from the Himalaya the outer process of the right harpe is hammer-headed rather
than simply outcurved. A related species with similarly asymmetric genitalia
(slide 14286) occurs in Sulawesi.
Java, Borneo; N.E. Himalaya.
