Show 614 MR. A. G. BUTLER ON THE GENUS ADOLIAS. [N Described originally as a species of Lexias, Boisd. Gen. ( = Sym-phcedra). The structural characters which separate Symphcedra from Adolias are not very considerable, and from their uncertainty seem almost to indicate a state of transition ; the style of coloration, however, is quite distinct. DlCHORRAGIA, g. n. Typical species Dichorragia nesimachus. Most nearly allied to Apatura (A. erminia), but differing slightly in the neuration, the hind-wing cell being partially closed by an interrupted and rather delicate lower discocellular nervule. In colouring the type more nearly resembles Symphcedra cyanipardus 2 than anything else, which probably accounts for its retention in Adolias. DlCHORRAGIA NESIMACHUS. Adolias nesimachus, Boisduval, in Cuvier's Regn. An. e'dit. Cro-chard, Ins. t. 139. fig. 1. Northern India. cf 2, B.M. STIBOCHIONA, g. n. Typical species Stibochiona coresia, Hiibner. Allied to Diadema (D. alimena), but differing from it, from Apatura, and from Adolias in having the discoidal cells of both wings distinctly closed, the middle and lower discocellulars of front wing forming a continuous arch, the upper discocellular of hind wing obliquely arched, the lower a little longer than the upper, slightly arched, and meeting the median nervure somewhat obliquely at the origin of the second and third branches. Colours intermediate between Adolias cocytus and Diadema alimena. 1. STIBOCHIONA NICEA. Adolias nicea, G. R. Gray, List Lep. Nepal, p. 13, t. 12. fig. 1 (1833). Adolias dolope, Felder, Wien. ent.

STIBOCHIONA CORESIA. 2 • Hypolimnas coresia, Hiibner, Exot. Schmett. Band ii. tab. 46. figs. 3, 4 (1806). cf. Adolias apaturina, Horsfield, Zool. Journ. v. p. 68, pl. 4. figs. 1, la (1835). Java. ^ 2 , B.M. The type of the genus Hypolimnas is a Diadema, so that that term cannot be adopted. |
