MR. F. MOORE ON LIMNAINA AND EUPLCEINA. [Apr. 17, 



I have not attempted the study of this group of American Butter- 

 flies further than what was necessary for the purpose of pointing 

 out its distinction from the other groups. 



Group LiMNAINA. 



Males, in most genera, possessed with one or more glandular sacs 

 or scent-producing organs on the hind wing. Hind wing also 

 mostly with a more or less defined precostal cell. Abdomen fur- 

 nished with odoriferous anal tufts of hair. 



Larva smooth, with two or more pairs of subdorsal, long, slender, 

 fleshy processes. 



Key TO THE Genera of Limnaina.
