separated al their places of origin. Hind legs with the tibiae much swollen: 

 tarsi nearly as long as the tibiae. Coloration: pale gray, with a decided 

 ochreous tint. 



The species of this genus may be easily recognized from the others 

 of the subfamily l>y the ochreous tints, the deeply serrate and angled wings 

 of the females, ami the angled male wings, as well as the narrow front of the 

 head. The sexes differ more than usual, and the species are exceedingly 

 variable.

2 9. — Of a uniform clear lawn-color, without the usual spots and 

 speckles: a basal, brown hair-line bent outward acutely on the median vein; 

 a broad, diffuse, dark median band (wanting in one example) common to 

 both wings. The extradiscal line is dark, finely scalloped, curved outward 

 below the costa and sweeping inward below the first median venule; beyond 

 this line both wings tire deeper fawn-color. At a little distance below the 

 costa, and nearer the extradiscal line than the outer edge of the wing, is a 

 conspicuous, angular, clear, white spot. Fringe dark, the scallops filled with 

 whitish. Hind wings like the. anterior pair, bu1 the extradiscal line is not 

 sinuous hut curved regularly outward. Beneath, paler than above; the 

 median band is distinct, and the extradiscal line more or less so ; the tints 

 are much as above. 



Length of body, 9, 0.40.; of fore wing, 9, 0.G6 ; expanse of wings, 

 1.40 inches.

This pretty species is so different from the two other species that it is 

 easily recognized by the absence of the clouds and spots and by the clear 

 fawn-color above and beneath. The single subapica! spot seems to be a per- 

 manent character. So differenf is it from the other species that M. Guenee 

 wjis misled into regarding it as the type of a distinct genus.
