Ernestia. 495 



in Almindingen; the dates are ^1-, — ^"/g. One of the specimens is 

 labelled as bred horn Euplexia lucipara on ^"/s (Weis); otherwise no 

 host is recorded (see below under remarks). 



Geographical distribution: — Europe down into France; towards 

 the north to southern Sweden. 



Remarks: Nielsen mentions (Vidensk. Medd. fra Dansk naturh. 

 Foren. 66, 1915, 215) that hc has bred the species from Mamestra 

 persicariae and gives description of larva and pupa and the biology; 

 but later on (1, c. 68, 1917, 26) he mentions that the host larva was 

 infested by two parasites, besides by the mentioned species also by 

 another, probably Voria trepida, and that the described larva and 

 the biology refer to this latter species, the pupa on the other hånd 

 to E. connivens, and only this species was bred. Now there are in 

 Nielsens collection only two specimens, a male and a female, belonging 

 to the mentioned bred material, and it proves that these specimens 

 were wrongly determined; both are E. radicum, to which species the 

 described pupa belongs. In the first cited place Nielsen declares, 

 that the determination of connivens is due to Dr. Villeneuve ; there is 

 also a specimen determined by this author, it is correctly determined, 

 but does not belong to the bred material on which Nielsens studies 

 were based. The host of E. connivens seems thus still unknown, 

 and Mamestra persicariae is added to the many hosts known for 

 E. radicum.
