Genus LEPTINA, Gn. 

 1852. Gn., Spec. Gen. Noct., i, 14. 



The types of all the species in this genus, with the exception of late- 

 bricola, Grt., are in the British Museum. Latebricola type, is in the 

 collection of the American Entomological Society, and is, as Mr. Grote 

 suggests, the same as dormitans. On the other hand, anstralis is not, 

 as I had supposed from specimens named by Mr. Grote, the same as 

 ophihalmica, but probably a good species. Mr. Grote has mixed vari- 

 etal forms of Guenee's species with his own. As the matter stands no\v, 

 after studying all the types, the species divide as follows: 



Shoulders and base of primaries concolorous DORMITANS. 



Shoulders and base of primaries white. 



Median lines complete, even, white DOUBLEDAYI. 



T. p. line incomplete, reuiform distinct OPIITHALMICA. 



T. p. line wanting, reniform wanting AUSTRALIA.
