 tant. 



Dorsum dark, without ornament; sub- 

 dorsal region pale ; stigmatal region dark. 



Piliferous spots subobsolete. 



When newly hatched jmle olive-green, 

 with very pale head and cervical shield. 



Body with eight superior, narrow, pale, 

 longitudinal lines barely discernible, the 

 two lowermost much farther apart than 

 the others. 



Dorsum pale, with median black spots; 

 subdorsal region dark ; stigmatal region 

 quite pale. 



Piliferous spots quite visible and large 

 on joint 11, where the pale lines generally 

 enlarge into white spots immediately in 

 front of them. 



When newly hatched dark olive-green 

 or brown, with black shiny liead and cer- 

 vical shield. 



Chrysalis.

 Imago, 



The first seven joints of the abdomen The first seven joints of the abdomen of 



of both sexes bear each upon tlie back both sexes with no spines upon the back, 

 two transverse rows of stiff, red spines, 

 pointing toward the end of tlie bodj". 



Front wings of male, on upper surface 

 ash-colored or brownish gray ; tlie whit- 

 ish spot found on the front wings of A. 

 ■pometaria is wanting. 



The whitisli bands found on the front 

 wings of A. pometaria are wanting, but 

 there is a jagged, subterminal white band 

 in most specimens, running out to the 

 apex, where it is lined externally with 

 dark brown. 



There are three interrupted, dusky lines 

 across the front wings, instead of two pale 

 lines, as in A. pometaria. Sometimes these 

 lines are only indicated by dark spots on 

 the costa and by blackish dashes on the 

 median nervure ; rarely are they very dis- 

 tinct thronahout tlieir whole extent. 



There is an oblique, blackish dash near 

 the tip of the front wings, crossing a nei-- 

 vure ; and thereis adistinctlj' interrupted, 

 or nearly uniform, continuous line of 

 blackish along the outer margin, close 

 to the fringe. 



The hind wings are pale ash-colored, or 

 very liglit gray, with a faint blackish dot 

 near the middle. 



The white band found on the hi;id wings 

 of A. pometaria is wanting. 



Front wings of male on upper surface 

 ash-colored with a faint purplish reflec- 

 tion, and with a distinct whitish spot on 

 the front edge near the tip. 



[Front wings] crossed by two jagged 

 whitish bands ; the outermost band has an 

 angle near tlie front edge. The white 

 bands are often entirely wanting, in which 

 case only the whitish spot near the tip 

 remains. 



Along the sides of the whitish bands 

 there are several blackish dots, each on a 

 nervure, and all generally connected to- 

 gether by a dusky band, which includes 

 them, and runs on that side of each whit- 

 ish band which is towards the other. 

 These bands remain visible when the 

 whitish bands are wanting. 



Within the angle of the outermost whit- 

 ish band, near the costa, tlierc is a short, 

 faint, blackish line, following a nervure; 

 and there is a row of black dots along the 

 outer margin, close to the fringe. 



The hind wings are pale ash-colored, or 

 light gray, with a faint blackish dot near 

 the middle. 



In most specimens a curved wliite band 

 is plainly visible on the hind wings, about 

 half way between the middle and the end
