The line on the hind wing is less curved in the ()regon s[)ecimen than 

 in that from Colorado, and the latter is deeper yellow. The occurrence of 

 this genus on the Pacific slope of the continent is extremely interesting as a 

 link connecting the insect fauna of Western America with Eastern Europe. 



It differs from the European ('. Jiuvaria in having broader wings, both 

 pairs i)eing much less excavated on the outer edge. TJie antenna^ are much 

 the same, and the markings similar in the two species. C flavaria is 

 reported in Staudinger's Catalogue as occurring in Galicia, Hungary, South- 

 ern and Eastern Turkey, Middle Russia, and Armenia.
