(Abstract.) 



In this paper are enumerated 80 species not previously recorded as 

 occurring in that month, bringing the total up to 283 species. Several 

 new species are described, as well as the hitherto unknown opposite sexes 

 of previously known species. Mr. de Niceville states his belief that in 

 Sikkim quite 500 species of Butterflies exist, and hopes to bring the 

 number of species occurring in the single month of October up to 350, 

 if not to 400. He also remarked that as far as he knew the richness of the 

 Lepidopterous fauna of Sikkim was exceeded by some parts of Brazil 

 alone ; and that the lists he was publishing should be very useful to Lepi- 

 dopterists, as previous records are few and brief respecting the exact 

 localities and elevations where the described Butterflies from Darjiling 

 occur. As a matter of fact but few species occur in Darjiling proper at 

 all, the majority of the so-called Darjiling species being caught by the 

 Lepchas in the low hot valleys in the neighbourhood. Mr. de Niceville 

 added that his excursions in the North -West and North-East of the 

 Himalayas proved that the bottoms of the valleys near the running streams 

 are the richest in Butterflies, and that next to these the extreme ridges 

 and tops of hills were most productive, while the sides and intermediate 

 slopes produced hardly anything.
