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



Section Megacbonycta, Grote. 



1. A. amert'cana, Harris. 



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

 cliow. 



"^2. A. dactylina^ Grote. United States. 



3. A. hastuUfera, Sm. Abb. 



*(;^. A. contacta, Walk. New York and 

 Hudson's Baj. 



In tlie 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 

 Icliang t- 



Section Abctomyscis, Hiibn. 



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



vonia, &c. 



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



3. A. euplirasioi^ Esper. Sicily, Russia. 



4. A. euphorhioi, 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^, part., Hiibn,). 



1. A. hercules, Feld. Yokohama and Tokio. 



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



3. A. luteicomaj Grote. Kansas. 



*4. A. pallidicoma, Grote. Illinois. 



*5. A. impressa, Walk. 



A. fasciata, Wallx-., and Verrillii, Grote. 

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

 Bay &c. 



t I hesitate to describe tlie latter, Messrs. Leech and Obertliiir having 

 done so much work in the Cliinese i'auua of late years as to render such a 

 course risky.
