AMERICAN LEPIDOFTKRA. 193 



mens now before me, and I have had none from other sources. The 

 resemblance to coloradensis is marked, and had I received such speci- 

 mens from Colorado, I would have had no hesitation in placing them 

 as aberrant or discolored examples of that species. Under the cir- 

 cumstances, since there is really nothing to show that the distinctive 

 characters are not permanent, it will be better to restore Mr. Ed- 

 wards' name to specific standing. 



For some time I have had in my collection three examples of 

 another species from Los Angeles County, California, differing from 

 all the others in the very even and very powdery light gray prima- 

 ries on which the markings are only a little relieved. In the even 

 color it differs from coloradensis, and in the very light powdery gray 

 it differs from frater. From all the species it differs in the practical 

 absence of the claviform which is barely indicated in only one ex- 

 ample. There are other differences in detail which convince me 

 that a good species is under observation, and to this I have applied 

 the name Cinderella. 



Rapllia Cinderella n. sp. — Very pale ashen gray, powdery; tending to- 

 ward a yellowish suffusion, the markings blackish, not contrasting. Head with 

 a dark line across the front and another on the vertex. Collar with a dark line 

 across the middle and another at tip. Patagia margined with blackish, and the 

 posterior thoracic vestiture dusky. The disc of the patagia yellowish. Prima- 

 ries with all the maculation present, darker than the ground, not contrasting and 

 sometimes almost lost in the general gray powdering. The tendency to yellow 

 tinting is mainly in the basal and s. t. space, while the blackish powderings tend 

 to mass along the inner margin. Basal line obscure, usually marked as a dusky 

 spot on the median vein at base. T. a. line geminate, the component parts widely 

 separated, inwardly oblique to the submedian vein, then with a long outcurve to 

 the inner margin near its middle. T. p. line geminate, even, slender, the outer 

 part obscure; rarely evenly and not deeply bi-sinuate, the course as whole par- 

 allel to the outer margin. There is a diffuse, irregular, broken median shade, 

 best marked by a dusky spot on the costa, obviously but less distinctly below the 

 submedian, S. t. line whitish, relieved by an irregular preceding dark shade in 

 the s. t. space. A series of blackish terminal lunules. The fringes are dusky, 

 cut with whitish opposite the veins. Orbicular round, moderate in size, consist- 

 ing of a dusky annulus which may or may not have a central dot in the inclosed 

 area. Eeniform varying in size and somewhat in shape, with a dark outline and 

 a dark central lunule which may extend to fill the entire spot. Secondaries 

 white, with a series of blackish terminal lunules, and a blackish spot at the anal 

 angle. Beneath white, powdery ; primaries with a vague tendency to reproduce 

 the most obvious markings of the upper side, especially the reniform ; seconda- 

 ries with a small discal lunule. Expands 1.36-1.48 inches = 34 37 mm.
