Head and thorax chestnut brown above, white or yellowish laterally. Front 

 whitish, palpi brown laterally. Patagije narrowly black edged and a fine black- 

 ish line margining the edge of the pale lateral shade. Metathoracic tuftings 

 black. Dorsum of abdomen yellowish brown, with a narrow black dorsal line ; 

 laterally the abdomen is black, with the anterior edge of the segments white; 

 the white scarcely forming bands, and not quite crossing the black shade. Be- 

 neath, thorax and abdomen dull white, with three or four blackish points along 

 venter. Primaries very pale yellowish brown, the markings deeper brown. A 

 brown shade along internal margin; from basal fourth of costa to basal fourth of 

 internal margin and making a very wide bend outwardly and over the discal 

 cell is a deeper brown line interrupted and giving rise to interspaceal brown 

 dashes, a series of which extends obliquely nearly to the apex; just within and 

 parallel to the outer margin is a whitish line, shaded on its inner side with 

 blackish, broken by the veins; an oblique black line, edged above with whitish 

 extends inwardly from the apex. All the fringes marked alternately with red- 

 dish brown and whitish. Secondaries dirty yellowish white, with a central and 

 submarginal blackish band, the outer margin of the same yellowish brown as the 

 primaries. Beneath, reddish brown on primaries with an indefinite and usually 

 incomplete outer darker band. Secondaries a paler red brown, with the macu- 

 lation of ujiper side more or less evidently reproduced, the median band dentate. 

 Expands 3.2.5 — 4.50 inches; 81 — 112 mm. 



Hub. — Can. to Georgia, Alabama westward to Missouri, Illinois 

 and Wisconsin. 



Probably found still further West and South, but I have no note 

 of such localities. The species does not seem to vary much, and is 

 very readily distinguished from all its allies by the color of prima- 

 ries. The genitalia are very much as in celeus as to the supra-anal 

 plate. The only male specimen I had for dissection seemed to have 

 no distinct clasper, but I think that is error in observation and dis- 

 section. The side piece is as in druplferarum. The larva has been 

 several times figured, but never very carefully described.
