 Costa darker than rest of wing, with pale strigoc.. Outer margin of wing 

 be.yond the outer whitish shade chisky. Fringe checla^red eonspieuously with 

 <hirlx, witli two narrow costal white checks just l)et()re the apex. Iliud wings 

 nnil()rni sahle-ash, with no markings; fringe checkered. Beneath, marbled 

 and mottled with wliite and Mack, reminding us of the peculiar markings 

 of C/iio/ioIxis. Fore wings with costal and outer margin marbled, inner por- 

 tion of wing uniformly salile. The three costal spots distinct as above, the 

 outer band disappearing entirely on the independent venule. An apical 

 vvliitish region, fringe on l)oth wings dark, checkered with black, and with 

 a slender line near the liase. Hind wings unil()rndy marbled over whole 

 surliice. AVithin the middle of the wing, a white, linear, transverse spot 

 comiecting the discal fold with the sid)e(>stal vein. Beyond tlie middle 

 of the wing, a, white i)and, distinct on the costal and inner edge, bid fading 

 out iu tiie nfuldle of the wing; each end of the band with a broad lilackish 

 patch outside; inner margin of wing blackisii. Legs blackish, spotted with 

 white. Abdomen with a row of Idack dots on each side.

The tiiree eostal sj)ots vary in either l)eing at equal ilistances apart, 

 though more usually the two inner spots are nearer together than the middle 

 and outer ones; otherwise it does not vary much. 



This beautiful species may at once be known by the three conspicuous 

 costal white spots, the outer terminating in a Hunt shade, and by the mesial 

 white band of secondaries being obsolete in its middle third. The beautifully- 

 mar])led under surface will at once distinguish it from any of our other moths 

 of this family. Tiu' Californiau ;)/. iiianimrata approaches Sdidosema iu the 

 acute primaries, and wants the two liasal spots on the costa.
