204 JOHN B. SMITH. 



of this pair is scarcely undulated or toothed, while the inner one gives off acute 

 angles on each vein. A bhick shade line starting from the ape.x obliquely, ex- 

 tend.s into the third pair of cross lines. A parallel dash crosses the outer pair 

 just below, and there are two and sometimes three parallel black dashes near the 

 middle of the wing extending from the median vein out to the outer pair of lines 

 between the veins. The fringes are white, marked on the veins with dark 

 brown spots, from which brown dashes extend nearly half way across the ter- 

 minal space. Secondaries dark smoky brown, lighter on the hinder margin, and 

 crossed by three parallel darker brown wavy lines, the outer rather a broad, but 

 indistinctly limited band. The fringes are white and marked with brown on the 

 veins. The under side of the wings is grny. The priniaries are crosscil out- 

 wardly by a dentate line and the oblique apical line is partly reproduced. The 

 secondaries are somewhat lighter and are crossed by two dentate yellowish brown 

 lines, one a little before the middle, the other a little beyond. Expands 3 — 3.75 

 inches ; 75 — 94 mm. 



Hab. — Canada to Virginia; westward to Illinois, Missouri, Iowa. 



This species is not uncommon. It varies somewhat in the depth 

 of ground color and the di-stinctness of the lines, but in no other 

 important point so far as I am aware. 



The supra-anal })iece has been already described. The side j)iece 

 is moderately long and narrows evenly to a pointed tip. The clasper 

 is a broad, corneous plate, somewhat curved, and the lower angle 

 drawn out into a long acute [xtint. The life history is tolerably well 

 made out by Andrews, Fernald and Lintner.

 Gray and olivaceous, the latter of a variably intense hue, but always distinct, 

 sometimes nearly blackish ; variable also in distribution, sometimes tolerably 

 even over the entire wing, more usually most prominent at base, terminally and 

 exteriorly between the double dentate black transverse lines which cross the 

 wing somewhat as in D. wididosa. On the whitish discal blotch is a small ringed 

 white spot, and a smaller dot is placed above this and obliquely outwardly at the 

 origin of vein six. A white apical shade limited inferiorly by an oblique black 

 zigzag streak. As in Ceratomia amyntor there are bla(;k dashes on the intersi)aces 

 running obliquely inwardl3'. but these are less prominent and diffuse than in 

 Hiibner's species. Fringes olivaceous, narrowly interrupted centrally with white. 

 Hind wings blackish, with double faint transverse shade lines, and with the ex- 

 ternal margin olivaceous. A fine terminal dark line, fringes as on the primaries. 

 Beneath fuscous gray, with double, transverse exterior common dentate line, and 

 on primaries the apical streak repeated. TeguUe olivaceous; disc gray. Ab- 

 domen dorsally olivaceous, iHterally gray, with a dorsal black line; two lateral 

 stripes and a stigmatal line on each side. Head above and collar olivaceous, the 

 latter with two black lines and the tegulie are lined ; sides of thorax and collar 

 whitish. Antennse white outwardly. Expands 3.75— 4.10 inches; 94- -102 mm.
