386 Lepidopterological Contributions. 



it had been very confusedly used by authors, Hiibner proposed 

 a new name for it ; the change is, however, hereby rendered 

 unnecessary.

Among other interesting Mexican moths, we have received 

 a $ specimen which we are disposed to regard as Ammalo 

 helops, Cramer, sp. It is a brighter, more distinctly marked
