meu. The genitalia of $ are like those of observahilis. As Mr. Grote 

 suggests, this species closely resembles formalis except for the coiicolor- 

 ous collar ; the black filling in of the cell is not distinctive. 



Rliynchagrotis distracta Smith, sp. nov. 



observahilis t Smith. 



1887. Smith, Proc. U. S. Nat. Mu8., X, 454. 



Clay yellow or grayish, more or less powdered with blackish. Costa 

 slightly paler. S. t. space strongly powdered with black, but not darker 

 than the median space. Cell as usual, black or dark filled. Transverse 

 lines geminate, black, complete, course as in the preceding species. 

 S. t. line pale, emphasized by a black costal patch and a slight preced- 

 ing blackish shade. Secondaries fuscous. Collar concolorous. 



Expands 32-34""" ; 1.28-1.3G iuches. 



Habitat. — Washington, Oregon, California. 



Varies in the direction of a more even color, the black powderings 

 less distinct, the cell not black though dusky. The species has a pe- 

 culiar sordid appearance, and the dense blackish atoms with which it 

 is powdered, add to this appearance. It is not unlike exsertisigma in 

 color and habitus though evidently distinct by the concolorous colhir. 

 This one is of the forms which was marked ohservabilis by Mr. Grote, 

 and which I so referred as above cited. 



The harpesof themale have the superior process somewhat lengthened 

 and somewhat clavate, and the inferior angle acute. The clasper is 

 very short and rather thick.

*' 9 Fore tibiie unarmed; appearing allied to attenta. Fuscous or 

 wood brown. The geminate lines as usual in this group. Cell black. 

 Stigmata concolorous; orbicular elongate-ovate; reuiform upright. 

 Subterminal space the darkest. The general color is fuscous with a 

 gray shade except on subterminal space. The distinctive character of 

 this species is the black shading around the orbicular of the cell. 

 There is a trace of the claviform. Hind wings pale fuscous with inter- 

 lined fringes and the veins marked. Beneath paler with a faint line 

 and discal mark."

This is slightly darker, more grayish than distracta, with which Mr. 

 Grote has also confused it. This species diflers in the more even color- 

 ation, the less distinct transverse lines, the dark, uniform s. t. space, 

 and in the tendency of the orbicular to close superiorly. This last 

 character is peculiar in this section, and while the species undoubtedly
