 = Euxanthis, Bb. (Myk). TYPE hamana, L. 



We have been unable to examine the type of this genus, so 

 have accepted Lord Walsingham's determination. The 

 genus was created by Hubner for his new species sartana. 

 We understand this species is somewhat indefinite and 

 should much prefer that Hubner's name Euxanthis be 

 retained until an opportunity arises for the type to be 

 examined.
