angle, 
Having now arrived at the conclusion of the descriptions of the insects 
referred by Dr. Horsfield to the Vermiform stirps of Papiltonide, we 
here again suspend for the present our analysis of his valuable work ; 
deeming it better to defer our notice of those of the Chilognathiform 
stirps until the account of them, which is only commenced in the second 
Part, shall be completed. We shall then attempt to give a connected 
view of the whole of that great subdivision of the tribe, so far as it is 
illustrated by the East India Company’s collection. To repeat our ad- 
miration of the beauty of the plates, the correctness of the figures, the 
nicety of the dissections, and the extent of the illustrations of the meta- 
morphosis would be unnecessary. Far superior in scientific value to any 
which have yet been devoted to exotic insects, these illustrations are un- 
equalled even by the most finished of those works in which the authours 
have applied themselves solely to subjects indigenous to the countries in 
which their publications were proceeded with, and where every facility 
for acquiring full information was consequently at all times in their power. 
To the extent, the accuracy, and the minuteness of the details conveyed 
in the text an almost equal praise is due. In the latter point even an 
exceeding is perhaps to be remarked, and this is particularly striking in 
that form of expressing the character of an insect which is usually re- 
garded as indicative of its specific difference ; it is here carried in many 
instances to the length of an extremely minute description. The labo- 
rious diligence of the authour is indeed every where remarkable. Each 
species is described with accuracy and precision from the materials in his 
immediate custody, and the extent and nature of these materials are in 
each instance specified: reference is made to other cabinets in which 
some of the insects are contained, especially to the very large collection 
of Papiliones, (Linn.), possessed by Mr. Haworth, and to the Banksian 
Cabinet, which now belongs to the Linnean Society, and which is most 
instructive on account of the names having been affixed to the specimens 
by Fabricius himself; the works of previous writers are referred to, and 
correct synonyms are thus obtained, while their errors are occasionally 
corrected ; insects which have been before confounded together are ac-
