8 t? and 8 9. — In the shape of the wings, this species closely resembles 

 H, californiata; the apex being pointed, the outer margin very oblique, and 

 the costa rather convex. The palpi, however, are shorter. Head, thorax, and 

 fore wings olive-green (or, when faded, reddish-brown). Hind wings and 

 abdomen pale-ash, with a dark dorsal abdominal line. Fore wings dark olive- 

 green (or reddish instead), crossed by six smoke-colored bands. The basal 

 line linear, directed obliquely outward, but not waved. This is succeeded by 

 a smoky band, as broad as, or sometimes broader than, any of the others ; it is 

 curved regularly outward, with the edges quite regular. Just beyond, and 

 situated just before the middle of the wing, is a narrow band, curved and 

 sinuous, widening on the costa, and linear and wavy on the inner edge. On 

 the outer fourth of the wing is a broad, slightly sinuous, smoky band, dentate 

 on the outer edge except on the costa and inner edge ; a broad, marginal, 

 smoky band, with a row of intervenular, black, linear dots next to the fringe, 

 which is dull-ash or smoke-colored, with a darker line, and checkered along 

 the inner edge. Hind wings pale-ash, with two outer curved dusky bands, 

 while the margin of the wing is dusky; a dark, oblique, apical streak, some- 

 times'wanting. Beneath, the costa of the fore wings has five large, yellow- 

 ish-white, square spots, alternating with dark ones, from which proceed 

 obscure diffuse lines, corresponding to the smoky bands above. The margin 

 of the wing is finely peppered with light scales. Hind wings pale-ash, with 

 the lines faintly reproduced. Fore legs dusky, ringed with whitish; hind pair 

 paler, like the abdomen.

This pretty form differs entirely from all the other species in the outer 

 edge of the fore wings being broadly margined with smoke-color; in the second 

 band from the base being very broad and smoke-colored; in the general dis- 

 tinct olive-green shade on the fore wings; and by the light large checks on 

 the costa beneath. The markings are entirely different from those of H. tri- 

 fasciata and californiata; and, in this respect, it approaches H. b-fasciata. 

 The green portion is often of a dull brick-red. One such specimen, on being
