Dr. Horsfield's Lepidopterous Insects of India. 109 



wards the outer apical angle : in Ph. insularis they are gradually atte- 

 nuated towards the anal region, with a slightly rounded inner apical 

 angle. 



Having now arrived at the conclusion of the descriptions of the insects 

 referred by Dr. Horsfield to the Vermiform stirps of Papilionidce, 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 uimecessary. 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 lai-ge collection 

 o{ 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-
