56 BULLETIN 44, UNITED STATES NATIONAL MUSEUM. 



HABITAT. California; Washington; Vancouver. 



The type of costata in the British Museum is a very poor specimen, 

 without a head. The wings are, however, sufficiently characteristic to 

 make it certain that it is the species I have called binominalix, speci- 

 mens of which are in the U. S. National Museum, the type in the Tep- 

 per collection.

HABITAT. Washington ; Oregon ; California. 



The type of Icetula is in the British Museum and is the same as the 

 form named distracta by me. 



R. discoidalis Grt.

 HABITAT. Nevada; Portland, Oregon, in June. 

 This species has been correctly placed by me, as appears by the type, 

 in the British Museum.

HABITAT. California, July and September. 



The type in the British Museum is nothing like the specimens so 

 named by Mr. Grote in Mr. Neumoegen's collection, and which I ac- 

 cepted as correct. The real species I had not seen before. In size it is 

 like alternata and there is a distinct blackish costal patch in the s. t. 

 space preceding s. t. line. In the character of the ordinary spots it is 

 nearest to discoidalis. I find four specimens of the species in the Na- 

 tional Museum, which have been more recently added to the collection.
