The central, obli(|ue, pale fascia which proceeds from the apex, is nar- 

 rower, more irreguhir, and less neatly defined than in either of the 

 above mentioned congeners. It joins the internal margin at nearer the 

 middle, widening on the margin, where it is composed of white scales 

 sprinkled with brownish. The nervules are obsoletely paler than the 

 ground color of the wing. The terminal space is wider than in D. Una- 

 ata and much as in D. chamfienc'rii ; fringes on internal margin white. 



Posterior wings smaller than in D. linen fa, very slightly excavate 

 before anal angle on external margin, which latter is more rounded than 

 in allied species. A median dull red band, narrowest at costa, nowhere 

 undulate or constricted, becoming white on internal margin, somewhat 

 as in D. chamaeneru. Base of the wing dull blackish, paler along costa ; 

 the subterminal dull blackish band is straight, nowhere constricted or 

 undulate, slightly excavate between the nervules ; terminal space red- 

 dish, broader than in allied species; fringes white. 



Under .surface of both pair of wings quite similar to that of D. lliipata^ 

 but with a dark sub-apical zig-zag streak on the primaries from the 

 costa, and an interrupted straighter one on the secondaries, issuing from 

 the costa before the straight sub-basal transverse band, which latter it 

 joins before the middle of the wing. 



Head and thorax olivaceous-brown, darker shaded on the tegulae, 

 which are margined with white stripes, making four thoracic white 

 stripes as in D. livornica. Abdomen, dull pale brownish, with subob- 

 solete ornamentation ; the segments show alternately paler and darker 

 dorsal shade bands. The second and third segments show each a late- 

 ral black spot, of which that on the second segment is much the largest ; 

 no dorsal marks as in allied species ; the segments laterally show dis- 

 continued white margins, of which the first is continued across the ab- 

 domen above. Antennae whitish, paler than in allied species, much as 

 in DeilcphUd Eiiphorhise, from Europe. 



One male specimen. Exp. % , 2.70 inches. Length of body, 1.50 

 inch.

I dedicate this species — which I have compared studiously with its 

 congeners, and am satisfied of its specific distinctiveness — to Mr. Ste- 

 phen Calverley, of New York city, whose kind as.sistance and advice l 

 have frequently had recourse to in scientific matters.
