This group is, therefore, distinctly Burmese in its distribution, and if 

 we ignore the wide-spread species from which it is difficult to draw con- 

 clusions, we find that one-third of the remainder are typical Burmese 

 species and do not range to the north of that country, that about one- 

 sixth are typical North-East Indian species, which within Burmese 

 limits only occur in the extreme north ; while the remaining species 

 which amount to half the total number are typical equally of Burma 

 and of North-East India. 



The second group, under which are included the species which affect 

 high elevations and which are only very rarely found below 4,000 

 feet, contains 92 species. These are for the most part Himalayan — at 

 least 74 species being found in the Eastern Himalayas, of which 28 

 extend to the Western Himalayas and a few to the hill ranges of 

 peninsular India ; in addition to the above four species — Arrhopala 

 dodo?icea, A. ganesa^ Celaenorrhinus j)ero, and Augiades hrahma — are 

 common to North-West Burma and the Western Himalayas, but have 

 not been found in the intermediate hill-ranges. Six species are 

 peculiar to the district, and a seventh is only found elsewhere in 

 Northern Burma ; of these seven, four are Himalayan and three 

 Malayan in their aJEnnities. Twenty-nine species extend as far south 

 as Lower Burma and Tenasserim, and 63 are not found to the south 

 of the present district, though most of these latter are found in the hill 

 ranges of Eastern and Northern Burma. 



So it will be seen that the Malayan element is almost entirely 

 absent from this group ; in fact, of the whole 92 species only seven 

 have been recorded from the Malay Peninsula. 



The third group, which includes species which are found at all 

 elevations from the terai to the summit of the hills, contains 67 species. 

 These, as might be expected from adaptability of flight, have almost, 

 without exception, a very wide range ; 64 are found throughout Burma 

 as far south as Tenasserim, and of these two only do not range further 

 to the north, while of the remainder 42 are of universal distribution 

 throughout the hills and plains of India ; 4 occur as far west as the 

 Western Himalayas, but are not found in peninsular India, while the 

 temaining 16 occur throughout Assam and Sikkim, but not further west. 

 The remaining three species of this group are peculiar to North-East 

 India and do not occur to the south of the present district.
