references. Tlie first must be added to Erotyla apicella, on page 

 37, line 24 of the List as follows: 



AgropMla tmncatula ZelL, Verb. z.-b. GeselL, 1878, S. 3, T. 3, fig. 1. 



The second to Metoponia obtusa, on page 37, line 35 of the List, 

 as follows : 



Metoponia ohtusula Zell., Verb. z.-b. GeselL, 1873, S. 4, T. 3, fig. 2. 



I have received the Transactions of the New York Agricultural 

 Society for 18G7, in which Dr. Fitch gives an account of the imma- 

 ture stages of Ehodophora florida Giienee, on pp. 900-904. Dr. 

 Fitch also describes as neAv Alalia volupia from " the Indian Terri- 

 tory west of Arkansas," on page 907. I have distinguished the two 

 genera in my List on the peculiarity of the armature of the fore 

 tibiae oi jlorida mentioned by Guenee, p. 171, Noct. 2, as also on 

 the different cnt of the wings. In the absence of any structural 

 details it is impossible to refer Dr. Fitch's voliqjia with certainty, 

 but, while I express the opinion with diffidence, not having seen Dr. 

 Fitch's type, I believe that Dr. Fitch may have described Oria san- 

 guinea Geyer under the new name. 



In Wood's Index Entomologicus OpJiius^a crassiusciila, PI. 17, fig. 

 436, very probably represents Drasteria erechtea $ , and should be 

 added to the synonymy of that species in the " List," p. 38. It 

 seems also that Erastria apicosa, PI. 17, fig. 454 is the same as Eu- 

 strotia nigritula (Guenee), of my "List." The former name is tlie 

 oldest, so that the species will have to stand : 



apicosa (Haw.) {Phytometra) ; Steph., Haust. 3, p. 119 {Erastria); Wood In. 

 Ent., 74, PI. 17, fig. 464; Erastria nigritula Guen., Noct. 3, p. 229, PI. 

 10, fig 7 ; Miana undulifera Walk., C. B. M. Noct. p. 258.* 



In an endeavor to account for the relations between the existing 

 European and American Noctuidous faunae we shall have to con- 

 sider first the species that may have been artificially introduced by 

 commerce. I think that Heliothis armigera may have to be included 

 under this head; it seems to be rather a southern and eastern Euro-
