(Continued from page 84.) 



Hysterosia Merrickana, Kearf.- -I desire to limit the type of this 

 species, a/ite page 59, to the specimens from New Brighton, Pa., 

 consisting of four males and two females, the former expanding 24-26 

 mm. and the latter 26-28 mm. I have two examples from Montclair, 

 which seem to be identical with those from New Brighton, but there is 

 sufficient variation in the specimens from the other localities to warrant 

 separating them, at least for the present, or until longer series or breeding 

 may prove them to be merely local races or distinct species. 



Until recently I have identified all of the ochreous-gray and ochreous- 

 brown specimens, having the characteristic dark oblique line from the 

 inner fourth to dorsal margin, and a paler basal area before it, as II. 

 inopiana, Haw.; but the accumulation of over one hundred specimens 

 from many different localities makes it possible to separate them into a 

 number of apparently different forms. The following may be added now, 

 and later it may be thought advisable to characterize eight or ten 

 additional forms which seem to be different : 



Hysterosia komonana, sp. nov. 



Head and palpi grayish-white, latter lightly shaded with brown outside, 

 antenna gray, basal joint ochreous brown ; thorax whitish-fawn; abdomen 

 light yellowish-gray, segments 6 and 7 light fuscous, anal tuft whitish- 

 fawn ; legs whitish-fawn, dusted and banded with bronzy-brown. 



Fore wing : Fold brown; an ochreous-brown shade from inner fifth of 

 dorsum turns under costa at middle, without reaching it; before this shade 

 the basal area is whitish-fawn ; beyond the shade the whitish-fawn ground 

 colour is strigulated with light brown. A darker dot at end of cell in 

 middle of wing. The dark strigulations are somewhat closer together in 

 apical end of wing, but not sufficient to form the dark apical patch that is 

 so characteristic of this genus. Cilia concolorous, but shining. 



Hind wing yellowish-gray, reticulated with light brown, cilia paler, 

 with a darker line near base ; under side the same. Under side fore wing 

 light ochreous-brown. 



Expanse, 22-26 mm. 



Nine specimens : Alma, Santa Clara Co., California, J. G. Grundel ; 

 Stockton, Utah, Tom Spalding.
