 An even blackish terminal line. Hind wings pale, with fuscous terminal shad-

 faint. Head and thorax pale gray; tegulae at the sides lined with blackish

Note. — On page eighty of the first Volume of the Bulletin I have 

 shown that Guenee describes the Apatela americana of Harris as 

 Acronycta hastulifera {Ahh. & Sm.). On the other hand Harris 

 identifies his species as the aceris of Abbot and Smith from the sim- 

 ilarity of the larvae. Prof. Riley has called my attention to his de- 

 scription of the larva of Harris' americana, which accords with Har- 

 ris and also with Abbot's figure of the larva of the species he dills 

 aceris. I find that Guenee has transposed, in his descrij)tions, Ab- 

 bot's larvae, perhaps unintentionally, but perhaps also correctly, and 

 since the figure of the imago of liastuUfera strongly resembles amer- 

 icana, wliilo the figure of the larva of aceris fairly represents the 

 larva of americana, these may be correctly associated under the name 

 liastulifera. It must be, however, doubtful, and I think we might 

 even prefer Harris' name with the following synonymy so far as 

 Guenee and Abbot and Smith are concerned.
