black; the lip is entirely black; the dorsal surface of the second segmenl 

 brown and shining, that of the following segments pale-brown or smoky- black, 

 of verj varied lint in differenl individuals, bul in each individual the tin! of 

 the dorsal area is pretty uniform as far as the spiracles: it is, however, inter- 

 sected throughoul by two distinct pairs of white stripes, the inner stripe of each 

 pair being the broader and more distinct; both are irregular and interrupted, 

 and just below the spiracles is a third white stripe, still more obscure anil inter- 

 rupted. This third stripe serves as a boundary between the dorsal and ventral 

 area. The ventral area, anal flap, and claspers are testaceous-brown; the legs 

 testaceous-brown, spotted with black. These caterpillars construct themselves 

 cells in the down of the sallow-seed, and therein change to bright-brown and 

 very glabrous chrysalids in the beginning of June. The caudal extremity of 

 the chrysalis terminates in two setiform processes, which are approximate at 

 the base, but divergent at the tip.'' — Newman's British Moths, 153.

6 $ and 3 9. — Of the ash-gray color usual in the genus, though rather 

 darker than usual. Body and wings colored alike; two dusky spots on the 

 prothorax, and two on each patagium. The fore wings are crossed by five 

 dark-brown bands ; the basal one goes obliquely outward from the costa to 

 the inner edge, being angulated on the median vein. Beyond is a band twice 

 as broad, dislocated in the median space; beyond, and close to the preceding, 

 is a band half as wide, and crossing the wing just before the middle. Just 

 beyond it is a faint linear discal mark, more distinct in the female than the 

 male; the middle of the wing is clear. In the outer third of the wing is a 

 narrow band, more or less scalloped like the others, and obtusely angulated 

 outward; a distinct, broad, submarginal band, deeply scalloped on the outer 

 edge, the scallops being deeply pointed; the band increases in width toward 

 the costa; the usual oblique apical streak partially conceals one of the scallops, 

 being very well marked ; outer edge of wing ash, not smoky. The veins and 

 their branches are black on the bands. Hind wings light-ash, crossed by 

 two faint bands, and not sprinkled over with black scales, as in the preceding 

 species; a very faint discal dot. 



Beneath, uniformly ash; the bands and discal spot very faintly repro-
