NO.1140. NORTH AMERICAN XOCTUIDAE— SMITH AND DTAE. 21 



The reniform is very narrow, upright, and somewhat imperfectly brown 

 ringed. Secondaries smoky, paler at the base, with a vague discal 

 lunnle and darker in the female. Beneath m hitish, a little darker on 

 the disk of primaries 5 secondaries with a smoky exterior baud. 



Expanse, 1.35 to 1.50 inches (34 to 37 mm.). 



Habitat. — Kittery Point, Maine, June and July; Massachusetts in 

 June; Rhode Island and New York, May, June, and July. 



This species differs from flavicor7iis in lacking all connection between 

 the median lines, and in this respect it resembles the si^ecies of Panthea 

 much more nearly than those of Charadra or Raphia, which the other 

 resembles in character of markings. There seems to be little variation, 

 except in the relative distinctness of the maculation and a little in the 

 distance between tlie median lines. As a whole the lower portion of 

 the median space is a little the darkest part of the wing.

Stage VI. — As in the next stage; but a few red hairs from wart I 

 the whole length, especially from joints G and 7. No black marks on 

 the body except on joint 2. Width of head, 2.5 mm. 



Stage VII. — Head shining red or blackish brown, pale on the clypeus; 

 width, 1 mm. Body very variable in color, the ground white with 

 numerous little transverse wrinkles of a more opaque white, and a 

 white substigmatal band, depressed at the spiracles and sometimes 

 broken or absent. Black shading usually begins at this band, border- 

 ing it above, spreading upward, especially in the incisures and below 

 around warts VI, till the body may be nearly all black. Hair sliort, 

 rather stiff, but not spinose, from distinct warts nearly in a transverse 

 line; IV very small; no secondary hairs. Hairs white or yellowish; 

 from wart II on joint 3, a red or black pencil; from wart I on joints 5 

 and 12, a red or black tuft, the pair forming a single tuft. Spiracles 

 white. 



This larva presents no good distinguishing characters from the 

 European Dcmas coryli. In my European specimens the black shading 

 seems to appear first dorsally rather than stigmatally, as in the Ameri- 

 can form, and a red tuft has persisted on joint G; but I doubt the con- 

 stancy of these characters. 



Cocoon. — Thin and frail; a few threads spun between leaves. 



Pupa. — Smooth, very shiny, the wing cases somewhat coarsely 

 wrinkled. Abdominal segments regularly tapering, perfectly smooth, 

 shagreened in the incisures. Oremaster large, thick, a little bulbous at 

 the end, corrugated and wrinkled, with a series of hooks at the end as 

 in Charadra. 



Food plants. — Birch, walnut, maple, oak, beech.
