2[ofh. — Two <? , one 9 . Ash gray, mixed with suow-white scales on the bead, thorax, and 

 costa and base of fore wings. Basal region of fore wings whitish and inclosing a eonspicaous 

 long bhxck line, extending along the cubital vein to the origin of the third cubital venule, and a 

 shorter one diverging from it situated in the discal space and ending at the base of the first 

 cubital venule; also a brown slash in the second cubital interspace. No transverse line on the 

 basal third of the wing. Near the apex of the wing are three subparallel black longitudinal 

 streaks. A transverse line on the outer fourth of the wing, which is obsolete on the inner edge 

 of the wing and faintly marked on the costa, with fine black specks on each side, and inclosing a 

 row of minute black dots. The veins and venules are speckled with black scales; two black spots 

 larger than the others are situated in the subcubital space inside of the cross line, and a larger 

 round black spot in the second cubital interspace, near the outer edge, besides a smaller one in 

 the first cubital interspace; they are encircled with whitish scales. A faint submarginal zigzag 

 brown line not reaching the apex of the wing and fading out near the internal angle. 



Fringe of both wings white, with a i)air of black twin dots at the ends of the venules; on 

 the outer edge of the fringe a dark slash situated opposite the ends of the venules. 



Hind wings sordid white, becoming dusty ou the outer fourth. In one 9 the hind wings are 

 entirely dark. 



Expanse of wings, 35-36 mm.; length of body, 17-20 mm. 



I copy Mrs. Slosson's description of 7). pitnta gorda, which appears to be a variety of 

 D. anguina. (See PI. IV, fig. 10.) 



Male. — Head and thorax appearing palest gray from admixture of pure white with cinereous. Abdomen, 

 secondaries, and ground color of primaries sordid white. Primaries streaked longitudinally with blackish, which 

 contrasts violently with ground color. A diffnse, heavy, blackish shade runs oliliquely from apex inward. A curved 

 blackish line, reaching neither costa nor internal margin at outer three-fourths of wing. .Submarginal row of 

 distinct, blackish spots, two of which are much larger than the rest and margined with white. Costa interrupted 

 near apes by wliite spots. Fringe sordid white, interrnpted by blackish. Somewhat smaller than D. anguina, 

 S. & A., and differing markedly from that species in its sliarp contrasts of color, which malce it appear like a purely 

 black and white insect. It has no oclierous shade. The autenn.c resemble those of D. anguina, the pectinations not 

 as long as in those of D. interna Pacliard. Described from two males taken at light, Pnnta Gorda, Fla. 



I received a few of the eggs of this moth from Miss Emily L. Morton, of Newburg, N. Y. The 

 young hatched July 25, and were led on locust leaves. 



Egf/. — Shape of a flattened sx^heroid, the upper pole somewhat concave, a little broader at 

 the base thau at the top. (Dyar says: "Evenly rounded, flattened above and below.") The shell 

 is very thin and transparent, so that the larva, with its yellowish head and red lines, can be 

 distinctly seen through it. The surface is covered with polygonal areas, which are not very 

 distinct, though as much so on the upper pole as ou the sides. The areas vary somewhat in shape, 

 size, and distance apart, the interspaces being rather broad, and there are no beads like those on 

 the surface of the eggs of Schizura. Diameter, 0.7-0.8 mm.
