Tati; and the Ramaqueban River, July 29, 1874. 9. (2) IDMAIS VESTA? Reiche in Ferret and Galinier’s Voy. Abyss. pl. 31, f. 7, 8. (Not of Trimen, p. 62, which = _Idmais Chrysonome_, E. Doubleday, Gen. D. Lep. pl. 7, fig. 5; nor of Klug nor Boisduval = _Idmais Hewitsoni_, Kirby, Syn. Cat. p. 498.) The specimens collected by Mr. Oates have the base of all the wings on the upper side broadly white, the remainder ochreous buff, with a large dark brown spot at the extremity of the discoidal cell of the fore wings, a dark brown, very irregular bisinuated fascia running across the fore wings beyond the middle, and extending across the middle of the hind wings, nearly reaching the anal angle; the outer margin of the fore wings is dark brown, with two rows of ochreous buff spots, the outer ones small; the outer margin of the hind wings is brown, inwardly dentated, with a marginal row of ochre spots. Beneath, the fore wings are bright orange-yellow at the base, yellow in the middle, with the apex and the entire hind wings brownish ochre, the markings of the fore wings ill defined, and with three obscure bands across the hind wings. In the female the ground colour of the upper surface of the wings is uniformly pale yellowish buff. The fascia across the hind wings separates this species from _Chrysonome_ Dbd., _Vesta_ of Trimen. M. Reiche’s figure apparently represents a larger and more suffused insect, the under side especially being more variegated, and the ground colour of the hind wings bright yellow.
