204 JOHN B. SMITH. 



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

 angles on each vein. A hlack shade line starting from the apex ohliquely, ex- 

 tends 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 

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

 brown spots, from which broM'n 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 baud. The fringes are white and marked with brown on the 

 veins. The under side of the wings is gray. The primaries are crossed out- 

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

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

 of ground color and the distinctness of the lines, but in no other 

 important point so far as I am aware. 



The supra-anal piece has been already described. The side piece 

 is moderately long and narrows evenly to a pointed ti}). The clasper 

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

 drawn out into a long acute jioint. 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. mididosa. 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 umyntor there are black dashes on the interspaces 

 running obliquely inwardly, 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, tran.'^verse exterior common dentate line, and 

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

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

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

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

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