THE BUTTERFLIES OF MUSSOORIE. 369 



61. Sephisa dichroa, Kollar. Plate U, Fig. 6, pupa. 

 Common at Mussoorie in the summer and autumn, the larva feeding 

 on the leaves of the common oak, Quercus incana, Eoxb., Natural 

 Order Cupulifercz. It is dark green in colour, and greatly resembles 

 the larva of Apatura ambica, Kollar, so Mr. Mackinnon notes. 



62. Dijlipa morgiana, Westwood. 

 Very rare in Mussoorie, the males on hill-tops in April, May and 

 September. One female only seen in September. Collectors bring it 

 from the Upper Ganges Valley. 



63. Apatura ambica, Kollar. Plate U, Figs. la, lb, larva ; 7c, 

 front view of head of larva. 



Males common in Mussoorie in April, May and June, and again in 

 September and October. The females are only occasionally seen 

 ovipositing on the leaves of Ulmus Walliehiana, Planch., Natural 

 Order Urticacece, on which the larva feeds. The pupa is pale greenish- 

 white, covered with a white powdery bloom. 



64. Hestina nama, Doubleday. 



Taken somewhat rarely in Mussoorie in March, April, July, August 

 and September, at 7,000 feet elevation, and in November as low as 

 3,000 feet. As female specimens have been taken as early a3 1st 

 March, it is possible that the butterfly passes the winter in the imago 

 stage of its life. It is a good mimic both in coloration and habits of 

 Danais sita } Kollar. 



65. Hestina [Parhestina) persimilis, Westwood. Plate U, 

 Figs. 8a, 8b, pupa. 

 Found in Mussoorie and in the interior from 3,000 to 6,000 feet 

 elevation from May to September. The larva, which feeds on the 

 leaves of Celtis australis, L., Natural Order Urticacece, is green 

 with spines on all the segments, those on the head being the longest. 

 Mr. Moore, in Lep. Ind., vol. iii, p. 35, pi. cci, figs. 2, 2a, male ; 2b, 

 female (1896), keeps Parhestina zella, Butler, from the Western Hima- 

 layas, as a species distinct from P. persimilis from the Eastern Hima- 

 layas ; but as the combined species occurs all along the Himalayas 

 and no line dividing them can be drawn either geographically or in the 

 specimens themselves, as far as we can see, the species has been given 

 here under its older name.
