This insect is one of the most abundant and widely spread in 

 the present genus, being commonly sent from almost every por- 

 tion of the Asiatic quarter of the globe east of Siberia; as might 

 be expected in a species possessing so extensive a geographical 

 rnnge it is highly variable both in form and colour, and has conse- 

 quently been described by the older authors and by Lacordaire 

 under many different names ; the species, at its extreme points 

 of divergence, presents two well marked types, one broad, less pa- 

 rallel and much more robust, the other longer, narrower and more 

 p.irallel; between these exists an unbroken chain of intermediate 

 varieties, thus proving that they belong to only one highly-variable 

 species. Although not entitled to the rank of sub-species or local 

 varieties, all the intermediate forms being found more or less 

 abundantly throughout the whole geographical range of the 

 species, still the first or broader type is the dominant one in 

 Southern Lidia, Ceylon and the Malay Archipelago, whilst the 

 second or elongate form is the one most usually met with in 

 Assam, Northern India and China.
