stoutly ciliated, with short, stoul pectinations. Thorax concolorous with the 

 front. Wilms pale cinereous, with two fine, basal, black, parallel lines, bent 

 onthecosta; a broad mesial band, deep black on the edges, consisting of 



four bands, the outer ones heaviest, and shaded diffusely within with black, 

 two-thirds as wide on the inner edge as on thecosta; a faint discal streak ; 

 the outer line of this broad band is very black, straight on the costa; on the first 

 median vein, ii has a large, acute tooth, of which the lower side is nearly con- 

 tinuous with the course of the band ; on the costa, one-bait' way between this 

 hand and the apex, is a square, dark spot, margined with white externally, 

 which is the beginning of a white zigzag line, continued to the inner edge of 

 the wing; beyond, the edge of the wing is dusky, with a marginal row of 

 geminate, intervenular, fine, black dots; fringe dusky at base, paler on the 

 outer half. Hind wings with no discal dot; two outer, zigzag, dark lines 

 parallel with the dusky edge of the wing, and a row of geminate, black dots 

 and fringe, as on the primaries; beneath, pale, with a luteous tinge ; on the 

 basal fourth of the costa is a conspicuous black spot; a mesial, curved, linear, 

 costal line; beyond is a sinuate, black line, most distinct on the costa; outer 

 edge of the wing dusky; fringe as above. Discal dots distinct on both 

 wings. An outer, curved, sinuate line, especially marked on the veinlets. 

 Fringe paler than on the fore wings. Abdomen pale-ashen, with a dorsal 

 row of black, geminate dots. 



Length of body, <?, 0.40-0.45, 9, 0.40-0.45; of fore wing, $, 0.43-0.G0; 

 expanse of wings, 1.00-1.15 inches.

This species may be easily recognized by its minutely-pectinated antenna', 

 each branch of which ends in a slight tuft of long cilise; by the long, dark 

 palpi, paler at the tip, the broad mesial band, both black on the (Miter and 

 inner edges, and not narrowing on the inner edge so much as usual: by the 

 broad dusky patch between this and the apex, margined externally by a white 

 line; and by the hind wings having two distinct waved lines on the outer half, 

 and also by the very distinct double row of black abdominal spots. 



When rubbed, the Californian examples look as in fig. 58. The Pacific-
