48 Captain T. Hutton's Notes on Indian Lepidoptera, 



extremely rare, for during a five years' residence at Mussooree, 

 I have never been fortunate enough to see a specimen either on 

 the wing, or in collections made here. In 1811, however, I cap- 

 tured a caterpillar, which I believed to belong to this insect, but 

 to my great disappointment, it produced nothing. I therefore 

 mention the existence of this butterfly at Mussooree, from having 

 seen a very exact painting of the insect, done some years ago by a 

 lady who captured a specimen near the village of Bhuttah, near 

 Mussooree. The evidence of its occurrence may be considered 

 insufficient, but this notice may induce collectors to make a close 

 search for the species. 



Sp, 3. P. Ejnus, 



Occurs in the Deyrah Dhoon, and likewise in the hills during 

 summer. Donovan gives the habitat " China," and Cramer, who 

 figures it under the name of P. Erithonius, (Plate 232, A B,) says 

 it is very common in China, Java, and on the coast of Coromandel, 

 but never at the Cape of Good Hope. I have received it from 

 Madras, and frequently took it at Neemuch, in Western India ; the 

 caterpillar feeds on the citron, and is green, with a reddish or orange 

 coloured head ; the fourth segment of the body is also bordered 

 with the same colour, and there is a lateral oblique stripe on the 

 hinder parts, which is blackish and edged with white ; the spiracles 

 are black ; there are two short tentacular horns projecting from 

 the anterior segment, and two others from the anal segment, 

 beneath which latter is a whitish stripe, running obliquely forwards 

 and downwards ; a white lateral stripe above the legs, which are 

 yellowish. It is very like the larva of P. Pammon, figured by 

 Horsfield, except that the latter has no tentacular horns. 



Sp. 4. P. Demoleiis. 



This likewise occurs in the Dhoon and in the hills ; it very 

 closely resembles the last, but is readily distinguished by the red 

 spot at the inner mai'gin of the lower wings, having a blue eye- 

 shaped mark above it. It is figured by Donovan as a Chinese 

 insect, and Boisduval gives the "coast of Guinea, Senegal, and 

 Madagascar;" Fabricius again gives the East Indies, and says 

 " the larva is solitary, smooth, of a yellowish green colour, with a 

 reddish head, two tentacles on the neck, and a bifid tail. Bois- 

 duval again applies this to P. Ejnus, stating that P. Demoleus has 

 been reared at Senegal by M. Dumolin, and that the larva feeds 

 on the citron trees." — (Westwood's Donovan's Insects of China.) 

 Boisduval seems to be right in referring this description of the
