This has been confounded by some Lepidopterists with /. sosunga 

 of Reakirt ; the latter, however, belongs to the genus Hymenitis. 



* Cramer's figure of T. psidii is that of a common Thyridia, and quite distinct 

 from the species figured by Bates, which appears to be an undescribed Methona, 

 exactly copying it in coloration. The latter is in the British Museum ; and the 

 name of M. confusa has been given to it : this will prevent the necessity of con- 

 founding the two genera, as proposed by Mr. Kirbv (Cat. p. 19).
