Oligia egens (Walker, )
Celaena egens Walker, 
The forewings are a rather complex and attractive rust-red on the basal two-thirds with some dark and light scales. The orbicular and reniform are outlined with lighter scales and partially filled with rusty orange. The distal third is light grey-white with greenish-yellow along the distal part of the light area. The area beyond the terminal line forms a narrow dark red-brown terminal band. The fringes are paler and lightly checkered with paler scales at the weins. The hindwings are sooty black, darker on the outer half beyond the faint black median line. The fringe is tipped with white. The thorax is light rusty green and the abdomen brownish-orange. The antennae are simple and the sexes are similar. Paler and more purplish forms resembling O. bridghami sometimes also occur. This description from E.H. Strickland Entomological Museum
