WALKEE'S TYPES IN THE BEITISH MUSEUM. 39 



Acronycta Impressa, Walk. 



The type, from Hudson's Bay, seems to be a small 

 specimen of Brumosa ; it is rubl3ed, and apparently 

 differs a little from that species ; it is hardly recog- 

 nizable. 



Acronycta Contacta, Wallc 

 Two specimens, from Hudson's Bay, belong to 

 the species described as Acronycta Aspera by Mr. 

 Morrison, and Folia D'lffiisllis by Dr. Harvey. It 

 is not an Acronycta. The species seems a Northern 

 one, and has been taken by Mr. Hill of Albany in 

 the Adirondack region of N. Y. State. It may be 

 known in future as Folia Contacta. 



Acronycta Grisea, Wallc 



I have hitherto correctly identified this species in 

 my own and other collections. 



Acronycta Mixta, WalTc. 



The specimen, from St. Martin's Palls, is Agrotis 

 Speciosa {:=Folia Perquiritata of Mr. Morrison). 



Acronycta Circulifera, Walk. 



As formerly stated by me, the specimens belong 

 to Charadra Dericlens, Guen. Mr. Walker had a 

 specimen of Jocosa wrongly named " Dericlens.''^ 



Acronycta Spiniger , Qum. 



Two (the larger specimens) belong to Morula , 

 the middle one is Harvey ana. Generally speaking, 

 Mr. Walker's identifications of Guenee's species do 

 not accord with my own.
