E. vicina is rare in Denmark, I know only three specimens, all 

 females, one from earlier time without particular locality, one from 

 Hareskov (the author) and one from Høbjerg near Æbeltoft (Kryger); 

 the dates are in June and July. The species is known as parasitic 

 on Deilephila galii and on the non Danish D. vespertilio and Pterogon 

 proserpina, and is also recorded from Lophyrus pini and sertijer. 



Remarks : The unique type specimen to T. vicina Zett. is in our 

 collection, and it is identical with the present species, as also com- 

 municated to me by Stein, who had seen the specimen. 



Geographical distribution: — Europe and down into North 

 Africa; not known north of Denmark.
