 Mo. IMag. 1864, 101). Mr. H. J. Elwes says it is " not so common, in Sikkim, as 

 Ehadamanthns \^^acus'], but has a wider range of elevation, and occurs during a 

 longer period of the year" (Tr. Ent. Soc. 1888, 422). According to Mr. L. de 

 Niceville it is " still more common in Sikkim than Rliadamanthus, occurring with it
