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



Section MEGACRONYCTA, Grote. 



1. A. americana, Harris. 



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

 chow. 



*2. A. dactylina.) Grote. United States. 



3. A. hastuli/erdj Sm. Abb. 



-*(. A. contacta, Walk. New York and 

 Hudson's Bay. 



In the Grote collection an example of A. americana was 

 labelled A. hastulifera] but the figure corresponds far more 

 closely with a female recognized as the latter and labelled by 

 M. 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. dbscondita, Treit. North Germany, Hungary. 



3. A. euphrasice, Esper. Sicily, Russia. 



4. A. euphorbia, Gmel. Switzerland, Germany, &c. 

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



*6. A. tota, Grote. Texas. 



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

 than to any species of the section Tricena, that I have without 

 hesitation placed it here. 



Section APATELA, Grote (APATEL^J, part., Hiibn.). 



1. A. herculesj Feld. Yokohama and Tokio. 



2. A. rubricoma, Guen. Philadelphia and Texas. 



3. A. luteicomaj Grote. Kansas. 

 *4. A. pattidicoma, Grote. Illinois. 



*5. A. impressa. Walk. 



A. fasciata, Walk., and Verrillii, Grote. 

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

 Bay &c. 



t I hesitate to describe the latter, Messrs. Leech and Oberthiir having 

 done so much work in the Chinese fauna of late years as to render such a 

 course risky.
