Oncocnemis Chandleri, Grote. 



HaUtat, Nevada (coll. Mr. Ily. Edwards, No. 2739). 



Hadena arctica, Boisdttval. 



Habitat, Sierra Nevada, Cal. (coll. Mr. Ily. Edwards, No. 3513). 



Hadena Bridghami, Grote. 



HaUtat, Sierra Nevada, Cal. (coll. Mr. Hy. Edwards, No. 3510). 



The single $ specimen is in bad condition, bnt from its whitish 

 secondaries and smaller size, while the ornamentation of the pri- 

 maries is very similar, compared with ardica, it seems to be this 

 species. 



Hadena dubitans (Walker), Grote. 



HaUtat, Sierra Nevada, Cal. (coll. Mr. Hy. Edwards, No. 3512). 



Hydroecia cataphracta, Grote. 



Gortyna cataphracta huj. scrip. 



Renewed examinations show me that the clypeus is smooth and 

 has no tubercle. I correct then my former generic reference in these 

 pages. The species can no longer be held to represent the European 

 Gortyna flavago on this continent, though the two are similar in 

 appearance and color. 



Gortyna piirpurifascia, Grote and Bohinson. 



A male from California (coll. Mr. Hy. Edwards, No. 135), seems 

 to be this species, while differing by the more yellowish median 

 spots on the fore wings. I have no longer my original material. 

 The male from California has a distinct clypeal tiihercle, and hence, 

 if my present determination holds, the only species to be referred 

 to Gortyna is the present; all the others wanting this tubercle, 

 are to be referred to Hydroecia, as I have already catalogued them.
