A large ( 6.2 - 9.0 cm. wingspan) narrow-winged heavy bodied moth with a striped forewing and pink hindwing. The forewing is dark black-brown with the costa a lighter olive brown, a blue-grey terminal band and a longitudinal pale yellow-brown stripe. The veins are outlined in white scales. The hindwing is bright pink, with a black basal area and a black terminal band. Both sexes are similar. The white veins of the forewing separate it from the other species of Hyles.
