butterfly does not occur in the area treated in this paper. We have a 

 single specimen taken in the Dun in July, which is exactly intermediate 

 between Forms II and III, as it has the yellowish-white markings on 

 the upperside of the forewing as in Form III, and a small patch of 

 white in and beyond the discoidal cell of the hind wing on the upperside 

 as in Form II. In Dehra Dun one of the food-plants of the larva 

 of this species is Murraya Kcenigiiy Spreng., Natural Order Rutacece.

 Figs. 22a, 226, larva ; 22c, 22d, pupa. 



Common in Mussoorie in March, April, and May, and very easy to 

 capture, as it returns repeatedly to the same spot even if temporarily 

 driven off. The female lays her eggs on the young leaves of Machtlus 

 odoratissima, Nees, Natural Order Laurinece, about the end of April. 

 The larva is at first of a reddish colour, but very soon turns black and 

 white, and lies on the upper surface of a leaf, where it greatly and 

 protectively resembles a bird's dropping. After the last moult it 

 assumes the handsome appearance shewn in the figures. The pupa is 

 found in June, the imago emerging the following spring. Felder 

 records P. agestor from " Masuri." Recorded by M. Oberthiir from 

 " Chukrata." 



260. Papilio (Chilasa) clytia, Linnaeus-. 



Not rare in Mussoorie in the spring and summer, and in the Dim 

 from the spring to the autumn. The butterfly is- dimorphic in both 

 sexes, the streaked form with pale markings generally known as- 

 P. dissimilis, Linnaeus, and the dark fuscous unstreaked form generally 

 known as P. panope, Linnaeus, both occurring in Mussoorie and the 

 Dun. The larva, which strongly resembles that of P. agester govindra 7 

 Moore, feeds in the Dun on Litscea sebifera, Perf.,. Natural Order 

 Laurinece. The pupae of both are also very similar, being remarkably 

 like broken-off twigs of dead wood. Felder records a var. of 

 P. dissimilis, Linnaeus, and P. panope, Linnaeus, both from " Masuri." 



261. Papilio (Sarharia) polyctoe, Boisduval. Plate W, Figs. 

 24a, 2 46 j larva ; 24c, 24^, 24<?, pupa. 



Very common in the low valleys about Mussoorie from March to 

 October, wherever the food-plant of the larva, Zanthoxylum alatum^ 

 Roxb., Natural Order Rutacece, is plentiful. A few specimens are 

 taken every year in the station of Mussoorie at about 6 3 000 feet
