CORRESPONDENCE. 



In reply to Mr. John Smith's remarks upon Capis, I would stale that 

 every student ought to know that in the Deltoids the eyes are always 

 naked, the tibiae unarmed. It was not necessary to recapitulate characters 

 conmion to the Group. As I have given a large number of generic 

 descriptions and reviewed in different papers and works the structure of 

 the Noctuidce, for the past twenty years, I think it probable that I gave all 

 the necessary characters, for the moment at least, until the male is dis- 

 covered, to establish the genus. In the Deltoid NoctiiidcB, as in the 

 Phycids and Tortricids, sexual structure is of generic value. It is very 

 easy now for Mr. John Smith to have his NoctuidcB named, and in response 

 to a private letter from him, I offered to name his material more than a 

 year ago. I am glad he seems to be studying the group, and I shall be 

 happy at any time to name his material and afford him any information in 

 my power. I think if he had applied to me I should have been able to 

 give him the facts as to Capis and the Deltoid genera which would have 

 rendered his article unnecessary. For, the structural details mentioned in 

 Mr. John Smith's letter, cited in the paragraph before the last, and for not 

 giving which in connection with Capis, I am blamed, are uniform through- 

 out the North American Deltoids so far as I have observed.
