 fuscescentibus velut in asoka, linea media velut in vacillaria at

 linea alis ambabus lunulari subtnarginali nigro-fusca : maculis 

 anticarum supernis niveis fusco cinctis: posticce linea angu-

Siam {a collections 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 con- 

 nexion with the cocytus of recent authors. 



$ . 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.

Allied to A. diardi, but seems distinct ; the male described pro-
