THE BUTTERFLIES OF MUSSOORIE. 373 



At de Niceville's suggestion Mackinnon sent his collectors in 

 August and September, 1889, to the Nila Valley, an affluent of the 

 Ganges, where they obtained this butterfly in large numbers, that 

 valley apparently being its headquarters in our area. It is quite rare 

 apparently to the west in the Baspa Valley. 



93. Argynnis (Brmthis) mackestnonii, de Niceville. 



A. mackinnonii, de Niceville, Journ. Bomb. Nat. Hist. Soc, vol. vi, p. 346, n. 3, pi. F, 

 Sgs. 4, male ; o, female {1891)„ 



Apparently rare, brought in by native collectors from the upper 

 part of the Baspa Valley, an affluent of the Sutlej, 11,000 feet, 

 and from the Gonas Pass in August. 



94. DlCHORRHAGIA NESIMACHUS, Boisduval. 



A single example has been obtained in the valley below the Old 

 Brewery in Mussoorie on 19th April, 1897. This species has an 

 immense range, occurring all along the Himalayas from Kulu to 

 Upper Assam : it is found also in Burma, the Malay Peninsula, 

 Sumatra, Java, Borneo, Celebes, the Philippine Isles, Western China 

 and Japan. Mr. Grose Smith has recently described an allied species, 

 D. nesseus, from Onei-shan, N.-W. China, which is said to be " con- 

 siderably less maculate" than D. nesimachus (Ann. and Mag. of Nat. 

 Hist., sixth series, vol. xi, p. 217 (1893). A third species, D. ninus, 

 Felder, occurs in Amboyna and Ceram. Herr H. Fruhstorfer has 

 Tecently named the North Celebesian form as D. nesimachus pelurius 

 and the one from Java, Sumatra and Borneo as D. nesimachus mannus. 

 Specimens from Java and Sumatra in de Niceville's collection are 

 absolutely indistinguishable as far as can be seen from Indian 

 examples.

Found at Mussoorie, on Nag Tiba and in Tehri Garhwal, the male 

 never common, the females very rare, in April, May and September.
