NOTE ON THE GENERA GORTYNA AND OCHRIA. 



BY A. R. GROTE, A. M., BREMEN, GERMANY. 



I have lately had an opportunity of examining bred specimens of the 

 European Oc/iria ochracea (flavago). The clypeal tubercle may be felt 

 with a fine pin or seen under the glass when the frontal scales are partly 

 removed. We have two North American species agreeing with Ochria, 

 viz., Sanzalitae, from California, and Buffaloensis, from the east. With 

 the former, the European species has a nearer resemblance externally ; 

 our eastern species differing much in colour. The type of Gortyiia Hiib., 

 is Aficacea, and the type o( HydrcEcia Guen., as indicated by an asterisk 

 in the Species General, is this same species. Consequently Hydrcecia 

 falls. The genus Ochria is used by Hiibner for the sole species flavago, 

 consequently this must obtain for the genus, which differs from Hydrcecia 

 of European authors mainly in the presence of the clypeal tubercle. While 

 flavago resembles in colour several North American species of Goftyna, 

 I may have overestimated its resemblance to our eastern cataphracta, 

 although a resemblance certainly exists. The type of Apamea is now 

 difficult to ascertain, but if, as I assume, it is really nictitans, it may give 

 way to the earlier Gortyna^ as the species do not seem to be generi- 

 cally separable. In Can. Ent., XIV., 17, I gave a list of the North 

 American species, which may be amended as follows : —
