Moih. — Two S , one 2 . Ash gray, mixed with snow-white seales on the head, tliorax, and 

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

 long black line, extending along the cubital vein to the oiigin of tlie third cubital venule, and a 

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

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

 bas;il third of the wing. Near the apex of the wing ai'e three subpaiallel 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 A transverse line on the outer fourth of the wing, which is obsolete on the inner edge 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 tine black specks on each side, and inclosing a 

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

 larger than the others are situated in tlie 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 pair 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 on the outer fourth. In one 9 the hind wings are 

 entirely dark. 



Expanse of wings, 35-30 mm.; length of body, 17--0 mm. 



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

 £>. anguina. (See PI. IV, tig. 10.) 



Male. — Head and thorax appearing palest gra.v 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 diffuse, heavy, blackish shade runs obliquely from apex inward. A curved 

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

 distinct, blackish spots, two of which are much larger than the rest ami margined with white. Costa interrui)tcd 

 near ai)ex by white Sjiots. Fringe sordid white, interrupted by blackish. Somewhat smaller than D. anguina, 

 S. & A., and differing markedl.v from tliat species in its sharp contrasts of color, which make it appear like a punlj 

 black and white insect. It has no oclierous shade, Tln^ antenna' resemble those of J), anguina, the pectinations not 

 as long as in those of D. interna Pack.ard. Described from two males taken at light, Punta 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 fed on locust leaves. 



Egg. — Shape of a flattened spheroid, the upper pole somewhat concave, a little broader at 

 the base than at the top. (l)yarsays: "Eveidy 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 jxilygonal areas, which are not very 

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

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

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