with pale buff. Head and body of female pale straw yellow, hind wings concolorous, 

 fore wings darker. Two broad purplish brown lines cross the primaries, the outer or 

 extradiscal edged externally with pale yellow. Intradiscal line broad, somewhat dif- 

 fuse throughout, begins on costa over one third out from base and is evenly outcurved 

 to inner margin ending a little farther in on that margin than on costa. A discal spot 

 •s barely indicated by a heightening in the ground color. Extradiscal line begins on 

 costa a little way in from apex as a narrow line and extends wavedly inwardly, becom- 

 ing wider as it proceeds, to M 2 , then forms an outward rectangle and continues 

 obliquely inward, turning out again before reaching inner margin. On secondaries a 

 single broad line concolorous with those on primaries but faint and diffuse begins on the 

 inner edge a little below the middle and extends inwardly curved to center of wing, 

 here it fades out in the male but can be traced as an outward and then inward curve 

 to costa in the female. Beneath, both sexes are uniformly pale creamy yellow on all 

 wings. 



Types. — Male in Brooklyn Institute Museum (J. Doll); female

Habitat. — Monterey Co., Cal. 



This handsome species differs decidedly from P. edwardsata Hulst 

 in the course of the intradiscal line. In edwardsata this begins at the 

 center of the costa and extends far out toward the outer margin of the 

 wing, then turns inward and runs sinuously to inner margin. In 

 spoliata this line does not begin out so far on the costa and is evenly 

 curved throughout. The extradiscal line is approximately the same 

 in both. 



14. Alcis addendaria, new species. 



Expanse, 34-36 mm. Head, thorax and body gray ; front, palpi and apex of 

 abdominal segments black. Ground color of wings light, whitish-gray in the male 

 darker in the female. Basal line not apparent. Intradiscal line present on costa 

 one third out from base as a black oblong mark directed tow aid anal angle, through 

 the discal cell it is obsolete or only vaguely indicated, is marked on the cubital vein 

 by a single spot, again fades out for a short distance and reappears very strongly near 

 the anal vein and sweeps far in on the inner margin. In some specimens this line is 

 internally edged with a diffuse shade of brown separated from it by a line of the ground 

 color. Extradiscal line begins on costa less than one third in from apex and is rep- 

 resented by a series of black venular spots which are more or less connected by a 

 diffuse line. Together they form a denticulate line, the spots at the apices of the 

 denticulations. From the costa it extends downward and roundly outward, then 

 sweeps far inward ending at the center of the inner margin. Inward of this line on 

 the inner edge the median line is indicated and occasionally a remnant of this is present 

 running through the diffuse patch of brown scales which represents the discal spot. 

 Outward of the extradiscal line and separated from it by a line of ground color is a 

 more or less denned broad, brown band. This is followed by a narrower band of 

 ground color and the remainder of the area is darker again and traversed through its 

 center by a denticulate, white line. Terminal line brown, evenly, outwardly seal-
