divided by a fine white line which runs through the center. Secondaries pale 

 yellow, more or less irrorate with brown atoms, especially toward inner mar- 

 gin. A single rather broad, diffuse line (sometimes absent) passes through 

 the center of. the wing approximately parallel to the outer margin. Terminal 

 line brown, narrow. Discal spot absent. Fringe light gray or brownish. 

 Beneath, both wings pale yellow, the primaries somewhat grayish on inner 

 and basal areas. Brown irrorations are present over the secondaries and 

 over yellow portion of primaries. 



Types. — Six males and three females in Dr. Barnes' collection and 

 in that of the author. 



Habitat.- — South Arizona, July 15-30, Aug. 1-15, and Gila Co., 

 Arizona, June (Poling) ; Redington, Palmerlee and Huachuca Moun- 

 tains (Barnes). 



This is the species referred to by me in the Proceedings of the 

 Entomological Society of Washington, Vol. X, p. 87, as Cymatophora 

 tenchrosata Hulst.* 



The specimens before me do not run so variable as those in the 

 National Museum but have tendencies in similar directions. 



The species is allied to Cymatophora inqninaria Hulst, but com- 

 pared with examples of that species at hand in smaller, whiter, far 

 less strigate on the primaries (which in the present species is scarcely 

 strigate when the atoms are profuse), and with comparatively 

 minute discal spot when this is present at all. 



Barnesia, new genus. 



Front slightly longer than broad, smooth ; palpi short, not extending 

 beyond the front ; antennas bipectinate to tip in both sexes, the pectinations 

 of the male long and somewhat clavate apically, those of the female short ; 

 tongue absent. Thorax and abdomen robust, the former tufted posteriorly, 

 the latter smooth. Tibia of anterior legs short, swollen, with two large, apical 

 corneous processes of unequal length which take the form of spurs ; epiphysis 

 originating near base of joint and extending beyond the shorter of the apical 

 processes. Middle and posterior tibiae with a single pair of spurs, the pos- 

 terior tibia without a hair pencil. Fore wings moderately broad, costal margin 

 very slightly concave, outer margin evenly rounded or with a trace of* an 

 angle at the center, veins R2, R3+4 and R5 on one stalk, no accessory cell ; hind 

 wing with outer margin evenly rounded or faintly angled at center, and angle 

 slightly pronounced, vein Sc anastomosing with R for half the length of discal 

 cell, M2 absent 



Type. — Barnesia ritaria Gross.
