The pea moth of economic literature, an introduced European spe- 

 cies. Its life history is given in the department and State bulletins 

 cited above. The type of Kearfott's dandana is a runted specimen 

 and smaller than normal examples of nigr^lcana, but in structure and 

 pattern it agrees. In Europe it has several synonyms. These are 

 omitted here as they have never appeared in our literature and have 

 no reference to American localities. The larva feeds in the pods of 

 garden and field peas and apparently has no other food plant. 



Hind wing with veins 3 and 4 stalked. 



Genitalia figured from specimens in National Collection from 

 Sturgeon Bay, Wis., reared July 14, 1920, by C. L. Fluke.
