Jan., 1883, p. 14, described larva on birch and poplar. This is 

 the true "representative" oi Leporiyia, quite distinct from either 

 of the above in all stages. " Birch Dagger." 



4. TOTA, Gr., N. Am. Ent., i, 10, Texas. This may not 

 belong here, and these are all the N. Am. typical Acronictce known 

 to me. The range of Felina (No. 2) may include Colorado. Not 

 enough material has been examined of t'us Western species. 



I am disinclined to place Insita with Acronicta. This form 

 should rather ioWow Aviericana and Dactylina under Mcgacronycta. 

 The final arrangement of our ApatclcE must be arrived at after all 

 the stages are known. Mr. Butler's paper on the genus was strik- 

 ing, but I am not prepared to follow conclusions based on one 

 form of the species alone. Apatela is a group or genus in which 

 the larvre have submitted to independent variation ; the gray color 

 of the perfect insect and its streaked pattern of marking has been 

 found useful and is preserved; this is apparent from a study of 

 the larvai of Psi, Tridens and Occidentalis. Dimorphism in the 

 larva is a break in the direction of a distinct cycle of reproduction. 

 In the two European species the break is considered to have pro- 

 ceeded far enough to warrant a title ; but is this really so ? I 

 have not in literature seen that* P^z and 7>/^^;« have been studied 

 sufficiently. It must be proved that there is a want of connection 

 between the two sets of larvae. Like Basilarchia in the butter- 

 flies, we have in Apatela a rich ground for collecting facts bearing 

 upon the natural rise of" species." I must highly commend Mr. 

 Thaxter's recent descriptions oi Apatela larvae. When these are 

 all known we shall know where to arrange such forms as Innotata, 

 Connecta, Radcliffei, and under what " sections." I have carefully 

 indicated the types of these " sections " from the names now in 

 use in literature according to priority. Those established by me 

 have the types all indicated. At present I am strongiy inclined 

 to believe that Eulonche {Oblinita, Lanceolarid) has more than a 

 sectional or sub genera value. I have worked very thoroughly 

 on the generic synonomy, and the student should study my Cata- 

 logue of the Noctuidae in the Bull, Buffalo S. N. S. for 1874, 

 where the typical species of each genus is given. I have, without 

 assistance, performed a good deal of labor with nearly 1600 

 species of the N. Am. Noctuidae. From what I expect, based on 

 what I have seen, we shall finally have to arrange about 2000 

 kinds of Noctuidffi. In doing this, the preliminary work I have 

 • accomplished is useful from the care I have taken to use the right 

 generic name, and I think uniformity may be properly secured by 

 adopting my new Check List as the basis in this respect (for in- 

 stance, in using Apatela, Glaea, Lithophane), since I have yielded 

 every debatable point as against the undiagnosed genera erected 

 by Hubner. There seems to me solid grounds for those I retain, 

 and, at any rate, my reasons are all given for what I have done. 

 I am not able to proceed in the publication of my general Mono-
