I have figured this species from a large and very imperfect 

 specimen, with the assistance of a fresh and good example, from 

 which I take my description : it is closely allied to dusara of 

 Horsfield. 



All the species from Malacca were taken close to the Govern- 

 ment bungalow at Ayerpanas, about sixteen miles from the town 

 of ]\Ialacca. 



XLVIII. — Description of a new Genus and Species of American 

 ^atyndce from the Collection of Mr. H. JV. Bates. . By A. G. 

 Butler, F.Z.S. 



[Plate IX. fig. 11.] 



The species upon which I found the i)rescnt genus was taken 

 by Mr. Bates on the River Amazons; and I am much indebted 

 to him for the pleasure of describing it. 



This genus is most nearly allied to Taygetis, which it closely 

 resembles in neuration ; in general aspect it more nearly ap- 

 proximates the genera Dadahna and Oxeoschistus, whilst on the 

 underside it somewhat reminds one of Corades.
