Darjeeling {Grote); Calcutta. Coll. F. Moore. 



Mr. Walker's description of this marvellously beautiful insect is very poor ; I should 

 never have recognized it. Fortunately Mr. Moore has been enabled to compare the 

 types of A. rubricosa and B. superba, and finds them to be synonymous. 



22. Ambulyx sexoculata. 



Ambulyx sexoculata, Grote, Ann. Lye. Nat. Hist. New York, viii. p. 204 (1867). 



Brazil {Grote). 



We have an Ambulyx from Guatemala, placed by Mr. Walker with A. gannascm, which 

 so nearly agrees with the description of the above, that I cannot help thinking it a 

 variety of it. The only difference seems to be that the ocellate spots on the middle 

 band of secondaries are so exceedingly undefined that, even with a lens, it is difficult to 

 make them out.
