three marginal ochreous spots. Fringe on both wings Ochreous, checkered 

 narrowly with brown. Hind wings with traces of the three bands of the 

 under side. Body beneath and legs ochreous. Fore wings brown, with the 

 eosta marked as above, with about five marginal, ochreous, oval spots along 

 the outer edge. Hind wings gayly banded with bright ochreous and silvery 

 white. At the base, a linear, oval, silvery spot parallel to the costa, the latter 

 being silvery, interrupted by an ochreous-hrown spot. Beyond, the wing is 

 crossed by three silvery-ochreous bands, varying in width, and often broken 

 up into spots; the outer row consisting of about six large, oval, contiguous 

 spots. Fringe broadly checkered with brown.

Waco, Texas. June 6, August is (Belfrage, Mus. Peab. Acad. 8c); Dallas, 

 Texas, May 15, "Hying on the prairies" (Boll., Mus. Peab. Acad. Sc). There 

 arc apparently two broods. 



In the female, the wings are a little longer; the apex of the fore wings 

 much more produced than in the male. This beautiful species may be recog- 

 nized by the peculiar ochreous, tan-brown color, the two square, costal, 

 ochreous spots, the gaily-colored under side of the hind wings, the three sil- 

 very-ochreous bands being faintly reproduced above, and by the broadly- 

 pectinated antennae. It differs from the European V. fascioIarKi, which it 

 represents in North America, in the broadly-pectinated male and narrowly- 

 pectinated female antennae. In the female P. fasciolaria, the antennae are 

 simple. The wings are also less produced, the hinder pair less notched on 

 the outer edge, and in no specimens yet seen are the costal spots continued 

 across the wing, sometimes forming regular bands, as in its European repre- 

 sentative. It varies but slightly ; in one case, the wings are suffused slightly 

 with ochreous, and the female is rather more ochreous than the male.
