P. BrassicoB, var Nipalensis. — Abundant at Umballa, in the plains, 

 and lip to 10,000 ft. altitude everywhere in the N.W. Himalaya. I 

 never saw^ it in Oudh. 



P. Gliciria. — Abundant in exactly the same localities as the last. 

 Both are on the wing in January. 



P. Namouna. — Appears rare : only two taken at Umballa in 

 November. 



Idmais Physadia. — One individual only taken ; caught flying low 

 in a field at Lucknow, in February. 



Anthocharis JEtrida. — Captured at Lucknow. 



Thestias jEnippe. — This is subject to considerable variation, and 

 the varieties seem constant to localities. The larvae feed on Qapparis. 

 I observe a constant difference in the Himalayan and Plains varieties, 

 apparently co-existent with, and dependent on, the species of Oajiparis 

 growing in their separate habitats. The Himalayan specimens from the 

 Sutlej valley are much greyer and finer insects than those from the 

 Plains ; and the luxuriantly-growing, large-leaved, and finely-coloured 

 lilac-flowered Gapparis (sp. ?) which covers like ivy the bold clifts over 

 the Sutlej, and affords pabulum to the Hill larvae, is a handsomer plant 

 than the coarse, straggling, thorny bush of the Gapparis sepiaria of the 

 diy plains, with its small white flower. Female specimens from 

 Wangtoo have the upper surface of the anterior wing dark black, with 

 an interrupted white transverse fascia ; the posterior wing dull black, 

 with a dusky -white disc ; whereas in female specimens from Umballa 

 the whole upper surface is clean white, the anterior wing only having 

 the outer margin and apes black, with a short series of marginal black 

 spots, and a short black streak from the middle of the costa. The males 

 are similarly, though not to so great an extent, unlike ; some females 

 have the apical half of the anterior wings pale yellow. 



T. MarianncB. — Abundant in Oudh, Umballa, and in the Himalaya. 

 The females vary a good deal in this species. 



Eronia Valeria. — Oudh and Umballa, but not abundantly. 



Callidryas Philipphia and G. Pyranthe. — Caught in Himalaya and 

 Plains. Larva reared on Gassia tora. 



G. Alaneone and G. Silaria.— Frequent the Gaihartocarpus fistula, 

 which is an introduced plant in gardens in the plains of N. India; 

 -but indigenous to the lower slopes of the outer Himalayan ranges, 

 2,000 to 5,000 ft. 



Oonepteryx Nipalensis. — Abundant in the Himalaya, 3,000 to 

 10,000 ft.
