Dr. Horsfield’s Lepidopterous Insects of India. 105 
After giving a character of the order, accompanied by some observa- 
tions on the important assistance to be derived in arrangement from the 
study of the metamorphosis, Dr. Horsfield thus characterises the Papi- 
lionide: “ Larva pedibus sedecim, elongata, cylindrica, tarda ; capite 
“< globoso retractili ; exserto, a corpore disjuncto. Chrysalis nuda, an- 
“* gulata, posticé alligata, sed vario modo suspensa ; in Stirpe Anopluri- 
“* formi subfolliculata levis, et Lepidopterorum aliquorum nocturnorum 
“chrysalidi similis. Imago: Antenne multiarticulate, basi graciles, 
* apice crassiores plerumque capitulate aut clavate, in paucis filiformes 
“« vel subsetacee vel apice graciliore uncinato. Ale insecto sedente erecte, 
** inferiores retinaculo nullo. In Stirpe Anopluriformi ale postice tantim 
“ erecte vel suberecte. Tibia postice plerumque apice solo calcarato. 
* Volatus diurnus.’”? This character is succeeded bya Synoptic Table ot 
the stirpes of the Papilionide, which exhibits at one view, with refer- 
ence to each stirps, 1. the analogies borne by it to the genera of 
Ametabola, MacL.; 2. its characters as derived from the metamorphosis ; 
3. its characters as derived from the perfect insect; 4. its synonyms; and 
5. the genera comprehended in it, these latter being distinguished into 
normal and aberrant. ‘The characters of the stirpes here given corres- 
ponding essentially with those contained in the Introduction, it is un- 
necessary for us to repeat the outline of them which we formerly gave 
at pages 122, 123, and 124, of our fourth volume. 
Commencing his descriptions with the Vermiform stirps, Dr. Horsfield 
again characterises its Jarva and pupa. Owing to the want of sufficient 
materials, he expresses his inability to proceed to the subdivision of this 
group into families so as clearly to define them. He states, however, that 
the genera Petavia, Polyommatus, Lycena, Thecla, and Myrina, are 
respectively representatives of so many families, the precise limits of 
which can only be determined by accurate and extensive investigation. 
Examples of each of the genera above enumerated, and of two others 
belonging to this stirps, are contained in the collection. 
In the genus Polyommatus, a new subgenus is distinguished under the 
name of PrrnEcops, by its “ wings somewhat elongated ; hinder wings 
** entire, regularly rounded, and elliptical.’’ Its representative in India 
is the Pith. Hylax, the Hesperia R. Hylax of Fabricius, of which a 
figure is given. The same form exists in Europe in the Pith. Alsus,
