53 BULLETIN 44, UNITED STATES NATIONAL MUSEUM. 



HABITAT. Canada to Middle States, west totlie Mississippi Valley; 

 Iowa; Colorado; Glen wood Springs in August; Europe; Northern 

 States, June to September. 



The European synonymy and bibliography are not given. In the 

 British Museum is a specimen marked Polyphcenis herbacea in what 

 appears to be Guene'e's handwriting, and this agrees very well with his 

 description. It is not the type. Guenee appears to have known 

 prasina from North America, but a large bright-green specimen such, as 

 is sometimes met with might easily have misled him into considering 

 this American form distinct. In the Cambridge Museum 1 have seen 

 a specimen of prasina labeled herbacea by Mr. Grote; it is unspread 

 and might easily serve as type of Guenee's description. The type is 

 in collection "Marchand"; but what has become of this I do not know.
