I have already cantributed three papers to the Jonrnal of this 

 Society on the Rhopalocera taken near Darjiling in October. In the last 

 of these papers, the number of species recorded as met with in this

 about twice the number of species found throughout the year in Calcutta. 

 These species were all taken at low elevations, either in the Runjit 

 Valley or on the roads between it and Darjiling, except in a few cases 

 where other localities are given ; and it is probable that many more 

 species will be discovered when some of the other valleys and the higher 

 elevations such as Senchal come to be explored.

A single male. In my previous paper,* I recorded that M. perseus 

 was very rare in Sikkim. It appears that M. blasius is equally so, which 

 accords with my lately expressed opinion that these hitherto supposed 

 distinct species are in reality but one species, which should stand as 

 M. perseus, the form that is usually called blasius occurring in the I'aius
