3 This species differs from Tntona in the whitish secondaries, but otherwise closely resem- 

 bles Hubner's species. I have examined the types in the British Museum. 



4 From the manner of remark on page 121 of the Second Report on the Insects of Missouri, 

 it would be inferred this species had been identified. I do not think it can be readily known 

 from the existing description.
