posteriorly with white. Wings pea-green, profusely strigated with irregular, 

 transverse, whitish markings ; costa of primaries narrowly edged with white ; 

 fringe whitish, occasionally with a narrow pink line at inner edge, and 

 marked with pink at the ends of the veins. There are traces of an outwardly 

 curved, white, inner line at inner third of both wings. A rather narrow outer 

 line crossing both wings is more defined, yet sometimes lost in the trans- 

 verse markings. On the primaries it is situated slightly inward of the outer 

 third, runs parallel to the outer margin and is somewhat scalloped. On the 

 secondaries it crosses outward of the middle, is decidedly scalloped and fol- 

 lows in general the course of the outer margin, being somewhat bent outward 

 below the median vein. Discal dots vague but present on all wings. Beneath, 

 uniformly green, paler than above, with faint reflections of the outer line of 

 upper side. Fringe as above. 



Types. — Two males and four females from Dr. Barnes (two of 

 the cotypes in my own collection) and one female from Mr. Frank 

 Haimbach and in his collection. 



Habitat. — Huachuca Mts., Arizona, July; Redington, Arizona; 

 South Arizona, July 15-30. 



Distinguished from its congeners by its large size and profusely 

 strigated wings. Aplodcs darwiniata rivals it in size, but in this 

 species the strigations are fine and exceedingly faint in comparison. 



g. Cymatophora trilinearia, new species. 



Expanse, 27-29 mm. Head whitish-gray, the front sometimes margined 

 with yellow. Palpi and antenna pale yellow. Thorax and abdomen whitish- 

 gray, the former with a narrow yellow collar, the latter tinged with yellow 

 which becomes more intense apically. Primaries whitish-gray, more or less 

 scattered over with brown atoms ; costa narrowly edged with yellow. Three 

 usually well defined pale brown lines of moderate breadth cross the wings. 

 Rarely these are represented by pale yellow spaces, or are somewhat obscured 

 by the profusion of brown atoms. The first crossing slightly outward of the 

 inner fourth extends outward from costa, turns downward within the cell and 

 thence runs almost straight to inner margin, being slightly curved inwardly 

 between the cubital and anal veins. The median line, sometimes reduced to 

 a mere shade, originates in a yellow costal spot, is either straight or curved 

 outwardly above Cu and inwardly curved below this vein, and precedes or 

 passes through the small round or elongated discal spot when this is present. 

 The outer line, also originating in a yellow costal spot, crosses the wing about 

 one-third in from the outer margin, extends outward from costa to Mj, then 

 inward to inner margin curving evenly outward before reaching that edge. 

 One-sixth in from the apex, on the costa, is a triangular yellow spot edged 

 with brown, and occasionally a second yellow patch is present in the outer 

 area between M3 and Cuo. A black terminal line showing between the veins, 

 more particularly in the central portion. Fringe gray or brownish-gray,
