taken about Philadelphia. The limits of the genus are clearly 

 reached, if not overstepped, with the present section. 



Sub-genus Apatela, Hubn. 



There now remain a goodly number of species which, per- 

 haps, fall into unnamed sections of the genus, and may, for the 

 most part, be arranged between the group Megacronycta and 

 Lepitoreiuna m. The best marked of these sections is that of 

 which the European Aiiricoma may be considered typical, and to 

 which the term Apatela must be specially applied. According to 

 Dr. Speyer's instructive article, the N. Am. Briunosa is related to 

 the European Aiiricoma. Guenee does not so regard it, but finds 

 in Rubricoina, Guen. and Luteicoina, Guen., MSS., species which 

 he found to resemble the European Auricoma in their immature 

 stages. I, myself, cannot now compare all these species, but it 

 seems difficult to further divide the American forms into different 

 sections or sub-genera. Thelarvce of but few, however, are known, 

 and it is upon the peculiarities of clothing in the larval stage that 

 I would chiefly rely in limitin;^ the sub-genera of Apatela. As to 

 this latter term I have fully shown that it must be retained for 

 the genus on grounds of priority. I follow Stephens in this. The 

 term is significant of the curious larval structure in this group 

 which we must call i?(?w/^_y^(?zV/te of Boisduval, and not Acro)iyetadcg 

 of Harris. The best name for the sub-family group^ of which the 

 genus Apatela is typical, is certainly APATELIN.-E. The Dasychi- 

 riform or Arctiiform larvae are of great interest and help to 

 bridge over the gulf between the two great families of BoinbjcidcB 

 and Noctiiidm. 



On the one side the sub-genus Apatela resembles SeinapJiora 

 or Triaena (the more significant title) ; on another they seem to 

 run into Lcpitoreuvia. I would add the following to my list of 

 Triaenae (Papilio, 3, ^']) : 



14. A. QUADRATA, Gr. Bull, B. S. N. S., 2, 154. This, with 

 the next following, is among our finest Apatelai. It is a stout, 

 rather short and wide-winged species, very distinctly marked, the 

 black dashes squared and cut off. " Square Dagger." The species 

 has been raised by Mr. Dodge from the larvse. Missouri and the 

 Western States. 



13. A. Radcliffei, Harvey. The exact position of this fine 

 insect, which has the primaries of a peculiar pearly gray, and the 

 hind wings whitish in the male, is doubtful. It seems allied to 

 the species I have described from Texas under the name of Tola. 

 The larva is not known, and perhaps this and the next are better 

 placed in the section Acronicta. Eastern and Middle States. 

 " Radcliffe's Dagger." 



16. A. Innotata, Guen., Noct. r, 50. Graefii, Gr., Proc. 

 E. S., Phil. 2, 68, pi. 3, fig. 6. This species varies in color, some 

 specimens being of a clearer, light fawn-yellow, others more grey 

 and clouded. It is curious to see how the lines copy the course
