conspicuous, the species varying much in this respect as If. sordidata, so thai 

 the varieties of the two species are apt to be confounded; the variety oi the 

 present species being distinguished by the whitish miter edge of the fore 

 wings, which in //. sordidata is smoky. 



The large female specimen I described as Cidaria glaucata is a form of 

 H. californiata. The head is whitish on the vertex and trout; palpi ash- 

 brown ; antennae minutely ringed with white and brown. Thorax and fore 

 wings pale glaucous-green. Fore wings with a brown squarish spot at base 

 ofsubmedian space; wing clear-green beyond, just within the middle crossed 

 by a broad compound band, directed obliquely outward toward the middle of 

 the inner edge ; the band is made up of two filiform, slightly-sinuated, black- 

 ish and red lines, enclosing, on each side of the median, wavy, smoky-gray 

 band, a broad green band; beyond is a broad clear space; a much sinuate, sub- 

 marginal, smoky band starts from the inner angle, and, after a long outward 

 curve, ends on the cost a (just below which it is dislocated), at a distance 

 from the apex equal to the thickness of the thorax ; some black and reddish 

 scales are strewn along the edge of the band ; from a squarish thickened por- 

 tion, as if broken off from the baud, reaches out toward the apical black streak 

 a similar short black stripe; a marginal, narrow, thread-like, black line. 

 Fringe whitish, dark at the ends of bands. Hind wings whitish, with two 

 parallel, curved, slightly-scalloped, dusky lines, situated nearer the outer edge 

 than usual. Both wings beneath pale-whitish, concolorous with the upper 

 side of the bind wings, with very faint indications of two outer, parallel, dusky 

 lines common to both wings. Legs brown, ringed with white. 



Length of body, 0.60; of fore wing, 0.70 inch.
