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 female 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 4con- 
thea primaria, one of the typical species, are figured on the eighth plate 
in the second part of the same work, where also the antenna, palpi, 
proboscis and feet are represented in detail; and in referring the reader 
to the illustrations which I have given of the larva and chrysalis 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 Lubentina, 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 4conth. 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 larve of diurnal Lepidoptera. The
