Mr. Henry Edwards has corrected the proofs of this list of the 

 genus Catocala, and authorizes my retaining the names Levettei, 

 Anna and Adoptiva, for the three species described by me. I need 

 not say anything as to Mr. Edwards' knowledge of the species 

 of Catocala and their Hterature. But I may say that he is thor- 

 oughly well acquainted with the facts in the controversy with 

 regard to these species. It is admitted by Mr. Hulst, represent- 

 ing Mr. Strecker, that I gave the names first to these species, as 

 also that Mr. Strecker antedated his number. I have shown 

 reasons for the opinion that Mr. Strecker had sheets of my paper, 

 printed in Philadelphia, and dated September, before him, when 

 he put the incorrect date, " August," to his number which 

 appeared in November. 



I am also indebted to Mr. Henry Edwards for his careful 

 revision of the proof sheets of the list of the Algeriadw. I have 

 received from the same Entomologist information as to the syno- 

 nymy of certain Western Sphingidce. In the GeometridcB I have 

 followed Dr. Packard's admirable Monograph, with but few 

 changes in the names or synonymy ; the BoarmincB are placed 

 lower down, as they appear to me to occupy an inferior position 

 in the family. I have not taken into the list the Desiderata of 

 Dr. Packard, except in a few instances. I have restored the 

 sequence of the Geometrida:, commencing with the highest genera, 

 as is customary. It is odd that in the " Brooklyn Check List," 

 where the intention evidently is to commence with the highest 

 forms in a family, an exception is made with the Gcometridce^ 

 which are catalogued upside down. 



The principal abbreviations used in this List are : 



G. &= R. for Grote and Robinson. Pack, for Packard. 



Gr. for Grote. Morr. for Morrison. 



Guen. for Guenee. Harv. for Harvey. 



Ily. Edw. for Henry Edwards. Led. for Lederer. 



Edw. for W. H. Edwards. Walk, for Walker. 



Zell. for Zeller. Fern, for Fernald. 



A. R. Grote.
