of the lower part of that in C. bifida Steph. (but not that shape). Its 

 internal border is arcuate in the male, more angular in ihe female. Its 

 outer border is twice indented, once at median vein and again on 

 submedian. The borders are very faint, hardly to be distinguished from 

 the rest of the band. Beyond the band are a few black scales on costa, 

 median and submedian veins. A minute spot on discal cross vein, 

 visible only in one specimen. Beyond this a very obscure undulated 

 diffuse line, hardly to be distinguished at all in the male, and a crescenti- 

 form line, darkest on the costa preceding the abbreviated blackish 

 subterminal band, which is broad on the costa, narrows to the first median 

 venule and borders slightly the crescentiform line to internal margin. In 

 this line are a series of small venular orange spots, and it is preceded by 

 a row of seven small venular black spots, the one on the costa elongated, 

 those opposite the cell faint. Terminal intervenular spots very small, 

 about as in C. aquilonaris Lintn. 



Secondaries white, with black discal spot and small terminal spots. 



Beneath primaries paler than above, shaded with black to correspond 

 with the bands. Secondaries white. Both wings have a large discal 

 black spot, and the terminal spots larger than above. In the female there 

 is a common macular median black band. Expanse 36-38 mm. 



Described from one male and two females from Los Angeles, 

 California. 



This species approaches C. ci?ierea most closely of any of the species 

 in Grote's list, but may readily be distinguished by its pale cinereous 

 colour and small marginal spots. Of the species added by H. Edwards * 

 it is not albicoma Strk., nor bifida Steph., both of which are before me. 

 Prof Lintner kindly informs me that it can not be near bicuspis Bork., 

 as this is allied to borealis Bd., and it can not be scoiope}id7'ina Bd., as 

 the author describes this as having the wings and collar white — " ses ailes 

 sont d'un beau blanc ainsi que le collier." f 



The species, therefore, seems distinct. Since writing the above I have 

 had the opportunity of comparing the larva of this form with that of 

 C. cinerea, and find the difference between them to be so slight as not to
