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- 

 lionidcB : " Larva pedibus sedecim, elongata, cyhndrica, tarda ; capita 

 " globoso retractili ; exserto, a corpore disjuncto. Chrysalis nuda, an- 

 " gulata, postice aUigata, sed vario modo suspensa ; in Stirpe Anopluri- 

 " formi subfoUiculata Icevis, et Lepidopterorum aliquorum nocturnorum 

 " chrysalidi similis. Imago ; Antenna: multiarticulatae, basi graciles, 

 " apice crassiores plerumque capitulates aut clavatee, in paucis filiforraes 

 " vel subsetacese vel apice graciUore uncinato. Ala insecto sedente erectae, 

 •' inferiores retinaculo nullo. In Stirpe Anopluriformi alae posticse tantum 

 " erectae vel suberectse. Tihias postica; plerumque apice solo calcarato. 

 " Volatus diurniis." This character is succeeded by a Synoptic Table ot 

 the stirpes of the Papilionidce, which exhibits at one view, with refer- 

 ence to each stirps, 1. the analogies borne by it to the genera of 

 Amefabola, 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 larva 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, Lyccsna, 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 Pithecops, by its " wings somewhat elongated ; hinder wings 

 " entire, regularly rounded, and elliptical," Its representative in India 

 is the Pith. Hylax, the Hesperia R. Ilylax of Fabricius, of which a 

 figure is given. The same form exists in Europe in the Pith. AlsuSy
