[NoTK. — From Massachusetts, Mr. Thaxter, No. 962; the species has no 

 clypeal horn, and my former reference of this species as congeneric with the 

 European flavago, is- based on an erroneous identification of the Californian 

 species as identical with purpurifascia G. & R.]

[Note. — I have been too hasty in considering the above two species as syn- 

 onymous. I have now a species which agrees with Guenee's description in 

 wanting the basal white marks on primaries, and is smaller and more red than 

 cerussata.]

[Note. — The Californian species (Mr. Edwards, No. 137, Mr. Behrens, 

 No. I'pl, Sept. 17) differs generically by the distinct clypeal tubercle, and ia 

 the only American species known to me that is to be referred to Gortyna of 

 Lederer {Ocltria Hiibner). The Californian species resembles purpurifascia, 

 for which I have formerly mistaken it in the " List," but differs by the t. p.
