316 Tachinidae. 



Lengtli 6,5 — 10 mm. 



E. hortulana seems to be rare in Denmark ; at Copenhagen and 

 at Valby and Søborg near Copenhagen, all bred from Acronycta 

 tridens and psi, except one which was observed attacking the larva 

 of tridens; of the bred specimens one came in April, another on i^/,; 

 further a specimen has been taken in Jutland at Hattenæs near 

 Silkeborg on ^^Z, (the author). Nielsen has (Vidensk. Medd. fra Dansk 

 Naturh. Foren. 1911, 8) treated its biology {E. blepharipoda) ; he 

 bred it from larvæ of A. tridens and psi, taken in September; there 

 were from 2 — 7 parasites in each host; he states that the larva bores 

 out and pupates in the ground, where it hibernates, the imago develop- 

 ing in June; I have, however, had an A. tridens larva in which the 

 parasites had pupated, and after hibernating the imagines came 

 from here, I have also seen a specimen bred from Acronycta leporina^ 

 not earlier known as host for it. The species is otherwise knowTi from 

 Pieris brassicae, Hyloicus pinastri, Malacosoma neustria and Taenio- 

 campa stabilis. 



Geographical distribution: — Europe down into France; not 

 known north of Denmark. 



Remarks: There is scarcely any doubt that ingens apud Stein 

 is the present species; at all events this is certain as regards the two 

 specimens from me mentioned by Stein; these specimens belong to 

 my above mentioned material.
