shade extends through the lower half of submedian interspace from base to 

 median shade. Orbicular oval, decumbent, broadly black-ringed, centered with 

 rusty. Reniform moderate in size, kidney-shaped, black-ringed, rusty-centered, 

 Secondaries white, with a slightly iridescent smoky shading which is most 

 obvious at hind angle. Beneath white, a little powdered, with a punctiform 

 extra-median line and a discal spot on each wing. 

 Expands 1.55 inches = 39 mm. 



Habitat.- — Sierra Nevada, California. 



One male in good condition, which has been in my collection for 

 twenty years or more. It is a conspicuous form and I have been 

 constantly hoping to get others — thus far without success. 



The antennne of the male are ciliate and the species is there- 

 fore related to /Arot/or/, to which also the type of maculation refers it. 



XYLOMIGES Gn. 



In re-arranging my specimens belonging to this genus {Xylomania 

 Hampson), I separated out the sexes of the long suites of the riibrica 

 series and noted, what I had not realized before, that all the uni- 

 formly colored specimens were males, and that all those in which 

 there was a curved black shading that separated off a more or less 

 contrasting apical area were females. It turned out that I had 2i(^and 

 20 $, and that these separated very nicely into three distinct types. 

 Of X. piilchclla Sm., I have 2 6 and i ?, and they differ from all 

 others in the very dark basal and s.t. areas, leaving the median space 

 contrastingly pale with only a slight reddish tint. The curved shade 

 in the female is broad, black and contrasting. They are from \'an- 

 couver, Laggan and N. \V. British Columbia without dates. 



Of X. rtibrica Harv., I have 8 males and 7 females coming from 

 California, Oregon, Washington, Colorado and British Columbia: all 

 early dates — IVIarch and April. Hampson had only 2 feiuales of 

 riibrica, one of them the type, and the figure 14 on his plate LXXXIX, 

 is a very good representation of that sex. Of X. pcrlubens Grt., 

 he had only the male type and that is figure 19 of the same plate, and 

 not so good a figure. There is no doubt however that it is the male 

 to Harvey's species, and is not my sitbapicalis, which has the sexes 

 similar and has a narrower curved shading on a much darker base. 

 Rubrica has the median lines distinct in both sexes, the coloring and 

 maculation is lively, and is a mottling of creamy, reddish and gray 

 tints, with the black or blackish brown curved subapical mark in the 

 female stronglv contrasting:.
