Luteous tawny. Anterior wings entire with a brighter shade ex- 

 tending along the costa centrally, and above the apical streak. Pro- 

 fusely and distinctly irrorate with dark-brown scales. Five transverse 

 brown lines. The first oblique, very slightly arcuate, and margined 

 inwardly with lighter scales. A central discal dot. The second line 

 curved outwardly at costa, thence running inversely obliquely to 

 internal margin. This line, which is margined outwardly with paler 

 scales, joins the first at internal margin in a single specimen before us. 

 A second discal spot. Tbe third line slightly arcuate at costa, thence 

 running parallel with fourth and fifth lines to internal margin. The 

 third and fifth distinctly margined outwardly with paler scales. The 

 fourth, which is quite contiguous to the fifth, is indistinct, and, in 

 some instances, almost obsolete. Apical streak obsolete superiorly, 

 indistinct. Fringes bright reddish-brown, the same with the thoracic 

 patch. 



Posterior wings very pale, with a paler median shade. 



Under surface paler than upper, shading to reddish-brown towards 

 external margin on anterior wings. 



The scales which clothe the head and form the thoracic patch, are 

 bright tawny-brown becoming darker towards the edges on the thorax. 



Metathoracic and lateral hairs concolorous with posterior wings. 



Abdomen pale tawny ; anal segment darker. 



Exp. % and 9 1.85 inch. Length of body, 0.70 inch. 



Habitat. — West Farms, N. Y., (Mr. James Angus). New Jersey; 

 Rhode Island; Long Island, (Mr. Harvey J. Rich.) 



Mature larva. — Head black, shining. Body, black, with four lateral 

 broad yellowish-white stripes, a fifth is interrupted centrally by the 

 legs as in D. ministra, but in this latter species the stripes are darker 

 and slightly narrow while the larva is larger than that of D. contracta. 

 The body is clothed with longer hair and is of a deeper black than in 

 D. ministra. The dorsal swelled portion of the prothoracic ring is 

 similarly colored but less prominent and exserted than in its congener. 



Food Plauts: Species of oak (Quercus) on which alone this cater- 

 pillar has been hitherto collected. (Auth. Mr. James Angus.)
