European Species of the Genus CJosmopteryx. 655 



larva mines the leaves of Vicia Septum; Orichalcea, with 

 the base of the wing brassy, and the apical streak interrupted, 

 of which the larva is suspected to mine in the leaves of 

 Festuca Arund'inacea ; and Druryella, with the base of the 

 wing brassy, and the apical streak entire, of which the larva 

 mines the leaves of Hierochloe Australis* In all these 

 species the margins of the central fascia, which are golden in 

 the male, have a rosy or violet tinge in the female ; and 

 though all have the tips of the antennae white, there is this 

 difference, that Druryella and Orichalcea have two white 

 rings before the white tips ; and in Schmidiella and Eximia 

 there is only one white ring. 



The synonymy of the species will be as follows : —

* I believe that Professor Frey entertains an idea that the insect bred from the 

 Hierochhe is distinct from the Druryella of Zeller ; but at present I am not aware 

 of any differences, and the description seems to suit exactly. 



t Tengstrbm has a Druryella in his " Anmiirkn. och Tillagg till Finlands 

 Smafjiiril-Fauna," p. 191, but I cannot now say whether the specimen which 1 

 then determined for him as Druryella was not Orichalcea.
