upon the amount of yellow mixed with the gray. The amount of pow- 

 dering on the surface is also a variable quantity, and sometimes it may 

 be fairly well covered with black atoms. Of the maculation, the costal 

 dots, representing the beginning of the ordinary lines, are the most con- 

 stant, and the dusky reniform comes next. The blackish orbicular may 

 be added in better-marked specimens, and finally the lines may become 

 fairly well indicated in the manner already described. The species 

 belongs to the pity chrous section of the genus and is somewhat related 

 to citricolor. The vestiture does not form evident tufts in any of the 

 specimens before me, and in that particular there is a resemblance to 

 some of the species allied to bostoniensis. 

 Type.— Csit No. 4146, U.S.N.M. 



9. CARNEADES LOYA, new species. 



Ground color an even dark mouse gray. Collar with a broad, con- 

 trasting, transverse band. Thoracic vestiture mixed scales and bair, 

 patagia marked, tuftings evident. Primaries with the ordinary lines 

 traceable only by black scales after close search, and they offer nothing 

 distinctive as far as can be seen. Subterminal line marked by yellow 

 scales forming irregular dots; preceded and followed by an irregular 

 dusky shading. Orbicular moderate in size, ringed with yellowish, 

 concolorous. Eeniform elongate kidney shaped, narrow, ringed with 

 pale yellow, centered with blackish. Claviform wanting. Secondaries 

 yellowish smoky at base, smoky blackish at margins; veins and adiscal 

 lunule blackish, fringes yellow at base, smoky centrally and whitish at 

 tip. Beneath, smoky fuscous, powdery, both wings with a discal spot 

 and a partly complete outer line. 



Expanse, 36 mm. = 1.44 inches. 



Habitat. — High Sierras, California (Dr. Dyar). 



One female, a little crippled, but so obviously unlike all the known 

 forms that I do not hesitate to describe it. It may be associated with 

 bicollaris, from which, however, it differs obviously. There is a possi- 

 bility that this may be the female of tocoyce (No. 25), but that would 

 indicate a range of variation that I am not ready to admit without fur- 

 ther evidence. Loya is the Indian name for the Sentinel, Dr. Dyar says, 

 and the specimen bears his No. 11278. 



10. CARNEADES FLAVISCAPULA, new species. 



Ground color dull fuscous brown, with small gray powderings. Collar 

 with a black line surmounted by gray scales, inferiorly with a reddish 

 shade which, at the base of the wings, forms a rusty red tuft. Prima- 

 ries very evenly dusty, the maculation not relieved, and traceable only 

 by careful observation ; yet it is all present. The course of the median 

 lines is as usual, and too faintly marked to show characteristic features. 

 Claviform indicated by dusky scales. Orbicular subquadrate, concol- 

 orous, defined by a few black scales and a narrow gray ring. Eeniform
