Show 1868.] MR. A. G. BUTLER ON THE GENUS ADOLIAS. 607 Borneo. Cj f B.M. Allied to asoka of Felder, but very distinct. 45. ADOLIAS COCYTUS, sp. n. (Plate XLV. figs. 3 & 10.) cf. Pap. cocytus, Fabricius, Mant. Ins. p. 29. n. 316 (1787). 2 • Affinis A. vacillariae, at supra characteribus fere aphidae (Hewits.); anticce maculis velut in vacillaria at minoribus et fuscescentibus velut in asoka, linea media velut in vacillaria at distincte nigrescente: area apicali anticarum omnino virescente; postica; lunulis tribus submarginalibus apicalibus nigris, albidis circumcinctis. Alee subtus omnino fiavida;, anticce disco toto late flavescente; linea alis ambabus lunulari submarginali nigro-fusca : maculis anticarum supernis niveis fusco cinctis: postica; linea angu-lariter arcuata discali fuscescente, characteribus basalibus consuetis: corpus supra fuscum, subtus flavescens. Exp. alar. une. 2-f. Siam (a collectione Banksii). B.M. The Fabrician type is in the Banksian collection, and, as I have stated in the 'Annals of Natural History' (Jan. 1868), has no connexion with the cocytus of recent authors. 2 . Above much like a small aphidas in pattern, but with the apical area covered with greenish scales ; below it is also somewhat like that species, but the hind wings are differently coloured and the bands distinct. In form it differs considerably, the front wings being strongly falcate and the hind wings with the anal area produced. 46. ADOLIAS GOPIA. 2 as cf • Adolias gopia, Moore, Trans. Ent. Soc.
