E. lota is very rare in Denmark, I possess only one specimen, 

 a female, taken in Egebæks Vang 2^/7 1915 (the author). On account 

 of the common confusion of the species with hortulana Meig. no sure 

 host seems to be known. 



Geographical distribution: — Europe down into France; not 



known north of Denmark.
