lilack; the lip is entirely i)ljick; the dorsal' siirfaee of the seeoiid segment 

 hrowii and 8hiiiiii!>:, that of the following' segiiieiifs pale-lirown or smoky- !)li!ck, 

 of very varied tint in ditierent individnals, but in each individual the tint of 

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

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

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

 and just below the spiracles is a third white stripe, still more obscure and 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 Ijeginning of June. The caudal extremity of 

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

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

6 c? and .'5 9. — 0( the ash-gray color usual in the genus, though rather 

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

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

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

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

 as broad, dislocated in the median space; beyond, and close (o 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 obliipie apical streak partially conceals one of the scallops, 

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

 tlieir l)ranches an; black on the l)an(ls. Hind wings light-ash, crossed by 

 two liiiiil bands, and not sprinkled over with l)laek scales, as in the preceding 

 species; a very liiint discal dot. 



Beneath, unil()rmly ash; tlie bands and discal spot very faintly repro-
