Cryptophasa byssinopis, n. sp.
Male and female, 42-45 mm. Head, thorax, and palpi white. Antennae in male white; pectinations 4-5; in female dark grey, towards base white. Abdomen white; second segment bright reddish-ochreous above. Legs white; tarsi annulated with blackish; anterior tibiae blackish anteriorly. Forewings elongate-oblong, costa moderately arched, apex rounded, hindmargin obliquely rounded; vein 2 from near middle of cell; snow white; with three blackish discal dots, first in disc at one-third, second in disc beyond middle, third beneath and posterior to second; a series of minute blackish dots on hindmargin; cilia white. Hindwings white, with minute hindmarginal blackish dots sometimes obsolete; cilia white.
The sexes are closely similar. Nearly allied to C. eugeniae, Luc., from which the male is readily distinguished by the white hind wings; the female is closely similar to that of eugeniae, but the black dots on margin of wings, especially hindwings are less developed, and sometimes obsolete.
