In my recent paper on new species of Sphingidw I have regarded this merely as a 
variety of J. passalus, allied to my M. proxima; I am now, however, convinced that 
it isa distinct species. I hesitated to separate it at first, on account of Cramer’s locality 
for M. belis being “ China;” it is, however, quite possible that both species occur in 
China, and still retain their distinctive characteristics. They are not more nearly allied 
than other Sphingide inhabiting far more restricted regions; and in a revision of any 
group of animals I am satisfied that it is far safer to err on the side of too much sub- 
division than of too little, much mischief having arisen as regards the multiplication of 
synonyms through the incautious association of different-looking forms together; Mr. 
Moore recived I. belis from the Himalayas.

Nearly allied to I. proxima. It is badly described, inasmuch as the primaries have 
two indistinct broad shining lilacine fascize across them which are not mentioned ; they 
are also chocolate-brown rather than black-brown; the orange band of secondaries is 
also dusky in the centre (a character not mentioned); and the anal tuft of abdomen is 
not varied with yellow, but terminates in a broad tawny band. The description is not 
quoted by Walker.
