 C— The Upper Tsang Po Valley, Jiily 13th to end of August; 

 elevation 8,500 to 11,000 feet, passes considerably higher. The 

 lower portion of this district, between Pe and Pemako Chung was 

 similar in character to the Po Ohu Valley ; higher up the country 

 was more like the dry barren mountainous region to the south, which 

 was traversed later. 43 species were obtained, many of which had 

 already been captured in the Po Chu Valley, while others were 

 obtained in the next district. 



The following species were not encountered elsewhere : 



A variety of one of the Po Chu JEreUas. 

 A]3liantopus kyperanthus . 

 Argynnis rudra and jainadev a. 

 Gonepteryx alvinda.

 the Subansiri between the Tsang Po and main range, which separates 

 India from Tibet, September; elevation 11,000 to 16,000 feet. A 

 dry barren country, which produced only 24 species, closely resem- 

 bling in character the butterjaies obtained in the Chumbi Valley and 

 round Gyangtse ; those of interest were : — 

 Vanessa urtica^ chinensis. 

 Argynnis eitgenia rhea and gemmata c/enia.

 I^rehia annada polypliemus. After October but little collecting was 

 done.
