766 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



the apical black patch are much larger, with more diffuse margins, and are increased 

 to six iu number by the addition of one between the first and second at the extreme 

 tip of the wing. 



Secondaries pure white ; all the veins black, with a narrow submarginal hand, 

 most remote from the margin about the middle of the outer edge. Occasionally the 

 veins are intensely black, with the scales spreading more or less over the disk of the 

 wing, in which case there are many powdery hlack scales, most concentrated along 

 the outer and inner margins, the former in this case having a narrow terminal black 

 line. Fringes white. 



In occasional specimens there are traces along the costa and on the outer margin 

 between the nervules of the red markings so characteristic of the female. 



Female. — The primaries differ from the male by the extension of the black apical 

 patch to the inner angle, it gradually narrowing thereto from the second median 

 nervule, and containing a small white spot between the first and second median 

 nervules. The same ornamentation is repeated beneath. 



The secondaries above are white, with a marginal and submarginal narrow black 

 band ; the nervules, black between these bauds, dividing the inclosed space into

six unequal lunules, as in the male beneath ; the outer band sometimes faintly inter- 

 rupted between the veins with a few orange or brick-red scales. 



Beneath, all the veins are broadly black, as are both the outer bands, reducing 

 the white spaces to a series of narrow intervenular patches and six reduced outer 

 lunules, giving the wing a very gray appearance. On many specimens there is no 

 red at all ; on others the whitish costal openings and a small patch in the terminal 

 black band between each of the nervules are of a brick-red. 



Habitat. — Country round Spokane Falls, Washington, July 26. 



Alar, expanse, male and female, 2, to 2.20 inches. 



Mr. Strecker's figure very fairly represents the upper side of the females here 

 described, but the under side is totally unlike, so far as the secondaries are concerned. 

 In all I have seen from the locality quoted there is more black than white on the
