NORTH AMERICAN LEPIDOPTERA. 161 



My material in this species was too scant to permit me to decide 

 on the synonymy, and, as the insect scarcely belongs to our fauna, I 

 have simply repeated Mr. Grote's description. For the same reason 

 I am unable to give a description of the % genitalia. I have seen 

 no United States specimens. It is readily recognized by the not 

 banded abdomen and large size. 



The early stages appear unknown.

"Head smok.y black on crown. nnn^Ied with grayish, with two white lines 

 between the antennfe. Thorax blackish, niintrled with sray ; a .double median 

 line, and the tegulfe and space at base of the wings gray. Abdomen dull iron 

 gray, with very faint blackish dorsal double line, enclo^iiit: a paler space. Sides 

 and undersides i>f both abdomen and thora.K white, thickly interspersed with 

 brown scales. Aiiteiinie with the shaft white, the pectinations fawn co'or and 

 the tip pitchy brown. Palpi and the whole of the legs white, with brown scales. 

 Primaries black, with a few gray scales intermixed, except on the apex and along 

 the internal margin, where the gray predominates. The wings are deeply 

 notched at the termination of the nervules, which are white and jet black, on a 

 grny ground. Secondaries dull red, with a whitish streak at base. The costal 

 maryins hIso whitish. Apex shaded with dull b'ack, continued around the mar- 

 gin to near the anal angle, where the usual mnrk of the genus occurs. In this 

 species it is a waved, broad line of black and gray alternately, the gray line 

 being double, the upper strongly toothed. The nervures are black as they ap- 

 jiroach the margin. Fringes gray, except on the abdominal margin, where they 

 are clear white. Underside of wings dull brici red at their base, brownish 

 toward the extremities, the margin speckled with black and white, and the 

 whole surface mottled with brown scales. Expands 2.6.5 inches; 66 mm."

This description is a copy of Mr. Edwards' original characteriza- 

 tion of the species, and like that gentleman's descriptions usually, 

 very accurate. 



INIr. Edwards says it is allied to D. ine/wicholica, but the wings and 

 abdomen are blacker, the marginal band of secondaries less distinct 

 and the anal spot more gray in color. The larva has not been de- 

 scribed. 



Since the above was written I have discovered two % s])ecimens 

 among Prof. Riley's material in the Museum collection. The one 

 from Texas, collected by Belfrage, agrees very well with Mr. Ed- 

 wards' description in all details. The other, without locality, was 

 labelled obscura, and Mr. Grote is given as authority for the name. 

 This specimen is much paler than the other, more ashen gray, the 

 veins black marked and a central longitudinal dark shade. The 

 specimen bears a very strong resemblance to an extremely di-stinct
