66 Dr. Horsfield's Descriptions of 



Feet: anterior with tarsi differently constructed in the sexes; in the 

 male consisting of a single elongated, attenuated joint, covered with a 

 dense uniform down; in the/emaZe with five joints of equal dimensions 

 as to breadth, but diversified in length, the first greatly lengthened, the 

 three remaining short, the last abruptly terminated, with several spines 

 along the edge of the three extreme joints. 



Observation. The detailed description of this genus being reserved 

 for the third part of my Catalogue of the Lepidopterous Insects contained 

 in the Museum of the East India Company, I have in this place merely 

 enumerated the essential peculiarities. The larva and chrysalis of .^^con- 

 thea primaria, one of the typical species, are figured on the eighth plate 

 in the second part of the same work, where also the antennae, palpi, 

 proboscis and feet are represented in detail; and in referring the reader 

 to the illustrations which I have given of the larva and chrysahs of this 

 very singular genus, it is very satisfactory to me to be enabled to state, 

 that it has also been observed by General Hardwicke on the Continent of 

 India. This accurate observer has confirmed the details I have given, in 

 all points; and he has, with his accustomed liberality, communicated 

 to me his drawings. These exhibit the larva in three different points 

 of view; that of the under side is particularly interesting, as it supplies a 

 deficiency in my own series. The feet, although very minute, are 

 distinctly exhibited ; they agree in number and disposition with all other 

 diurnal Lepidoptera. The pupa likewise, figured by General Hardwicke, 

 resembles in every peculiarity that which I observed in Java. 



In the second part of the work above cited, two species of Aconthea 

 are figured on plate v. ; the Aconthea Luhenlina^ being the Papilio 

 Lubentina of Cramer, and a new species from Java, named Aconthea 

 Alankara. My immediate object in this communication, is, to add the 

 description of a new species, the Aconthea Apaturina, which, though 

 not part of my collection, is, as far as has been ascertained, an oriental 

 species, departing slightly from the typical form ; and to illustrate an 

 obscure species, the Aconth. cocytina indicated indeed by Fabricius, but 

 not sufficiently discriminated from its neighbours in the series. 



The metamorphosis of Aconthea is very remarkable, and strikingly 

 illustrates the analogy which exists between the forms of the individuals of 

 the class of Ametabola, and the larvee of diurnal Lepidoptera. The
