48 AMKKICAN LEPIDOPTERA. 



spurs are rather acutely pointed, while the brown depressions between them 

 are rounded. The white band is continued at anal angle through lower half 

 of ocellic space and into cilia, which is pure white to the apex, excepting 

 a dot of brown just below apex and on outer shade of brown in middle of 

 wing. On the third white spur, just before ocellic space, is a large dot of brown 

 scales, connected by scattering brown scales, with a similar but less conspicuous 

 dot on dorsum. In eastern specimens these dark scales form a rather large trian- 

 gular spot resting on dorsum and entirely interrupting the white band, excepting 

 at its extreme upper edge. On extreme dorsal edge between this spot and base 

 are twelve or fourteen rather evenly-spaced brown scales; two or three of the 

 same are scattered over the upper ends of the first and second spurs. On the 

 costa, between fold and apex, five or six geminated short dashes, these are almost 

 obsolete on the western specimens. Costal fold about one-third length of wing, 

 closely compressed, narrow; concolorous with upper part of wing, and bearing 

 several geminate pale dots, which in the western specimens are reduced to tiny 

 specks on extreme costal edge. 



The dark color of the wing is more of a blackish-purple than brown, it is strig- 

 ulated with short, fine, irregular, black, transverse lines, more distinct along 

 costal and outer margins. Before the cilia a narrow line of more or less connec- 

 ted dark dots form a continuation of the line of dots on dorsal margin, and before 

 this dark line on outer margin a narrow shade of the white continues up, nearly 

 to apex, from the dorsal band. 



Hindwing: light pnrplish-fuscous, cilia paler, with a lighter and darker line 

 at its base ; same beneath. 



Underside forewing : purplish-brown, rather shining, costal and ciliate white 

 spots repeated 



Eight specimens : Nevada Co., Cal., Sept. ; Kern Co., Cal., Oct. ; 

 Placer Co., Cal., Sept. ; New Brighton, Pa., March 22d (F. A. 

 Merrick). 



Cotype in U. S. Nat. Mus. 



The outer margin is very oblique, at an angle of about forty-five 

 degrees from the dorsal line. In the California specimens the de- 

 pression at end of veins 4 and 5 is barely observable, the margin 

 being almost straight. The depression is more pronounced in the 

 Pennsylvania specimen ; apex rounded ; costa scarcely arched ; 

 forewing three times as long as wide. 



It is not impossible that fuller knowledge of the life histories of 



the western and eastern forms may prove them to be separate and 



distinct, in which case I would propose the name pe)insylvaniana for 



the latter. 



Proteoteras arizonte sp. nov. 



Expanse 18-20 mm. 



Head, palpi, antenna and thorax cinereous-white ; outer surface of palpi speck- 

 led with black, thorax speckled with fuscous, and posteriorly edged with black ; 

 abdomen whitish, shaded with light fuscous above; legs whitish, banded and 

 dusted with blackish-brown.
