398 ;Mr. A. G. Butler on the Genus Acronycta. 



Section Megacroxycta, Grote. 



1. A. americana, Harris. 



A. acericola ?, Guen. New York and Foo- 

 chou'. 



*2. A. dactylina^ Grotc. United States. 



3. A. hastuh'fera, Sm. Abb. 



*(J. A. contacla, Walk. New York and 

 Hudson's Bay. 



In the Grote collection an example of A. americana was 

 labelled A. hastnlifera] but the figure corresponds far more 

 closely with a female recognized as the latter and labelled by 

 j\I. Guenee. We have a fourth species of this group from 

 Ichang f. 



Section Abctomyscis, Hiibn. 



1. A. aceriSj Linn. Switzerland, Christiania, Li- 



vonia, &c. 



2. A. ahscondiia, Treit. North Germany, Hungary. 



3. A. euj)hrasiii'j Esper. Sicily, Russia. 



4. A. euphorbia'^ Gmcl. Switzerland, German}'', &c. 

 *5. A. sperata, Grote. New York. 



*6. A. iota, Grote. Texas. 



No. 6 is so much nearer to the dark variety of A. aceris 

 than to any species of the section Tritenn, that 1 have without 

 hesitation placed it here. 



Section Apatela, Grote (Apatel^, part., nUbn.). 



1. A. Jterculesj Feld. Yokohama and Tokio. 



2. A, ruhn'coma, Guen. Pliiladelpliia and Texas. 



3. A. lutei'coma, Grote. Kansas. 



*4. A. pall idicoma, Grote. Illinois. 



*5. A. impressd, Walk. 



A. fasciata, ]Vanc., and Vcrrillii, Grote. 

 A. brumosa, Grote (not Guen.). Hudson's 

 Bay &c. 



t I hesitate to describe the Litter, Messrs. Leech and Oherlhiir having 

 done so much work in the Chinese I'auua of late years aa to render such a 

 course risky.
