venation and habitus Lithosiid rather than Arctiid, and would prefer so 

 to place it, even despite the presence of ocelli. 



Lest Mr. Grote consider me ignorant, I will say here that I am aware 

 that there are some Noctuids which have the dorsal vein of primaries not 

 distinctly furcate, and some where the costal of secondaries is united with 

 the sub-costal a short distance from base, and thus appears to spring 

 from it. 



With this I leave Cerathosia to its fate. In my papers I have given 

 all the characters, family and otherwise, and shall let each form his own 

 judgment. It needs no more defence from me. In fact, I feel as though 

 I owed an apology for answering objections, not a single one of which is 

 vital. 



Mr. Grote's characterizations in his series of papers on the Bombycidce 

 are thoroughly superficial, none of the essential characters being 

 emphasized, while some of them are absolutely incorrect — his definition 

 of the Lithosiince furnishes an example. He says unqualifiedly, " No 

 accessory cell on primaries." Now, Von Heineman shows that in some 

 genera it is present, while as a matter of fact some species of LitJwsia 

 have the cell (cephalica), while others have not. It is therefore not even 

 a generic character in this group. To point out all the misleading and 

 inaccurate statements, would necessitate criticising almost every paragraph 

 of Mr. Grote's paper — a task I have neither time nor inclination for. In 

 future I shall not reply to any criticisms Mr. Grote may make, save to 

 admit their correctness where they are well founded. 



Postcript. — Since sending in the above, I have heard from Mr. 

 Moeschler in regard to the specimens sent him. He writes me under 

 date, Sept. 28th.: — "To-day I received the parcel containing the two 

 moths. I have examined them, and there is no doubt you are right. 

 This species belongs to the Arctiidce, as the costal nervule is not 

 derived from the base of the hind wings, but from the discoidal cell ; 

 this characteristic separating the Arctiidce and Lit/wsiidce from the 

 Noctuidce, which have this nervule derived from the base of the wing, only 

 a little connected with the fore edge of the cell. I do not doubt this 

 species is an Arctiid, near allied to Deiopeia and EmydiaT 



Under date Sept. 30th, Mr. Moeschler again wrote me : — " I received 

 Entomologica Americana No. 6 to-day, and it was of great interest to me
