cnT-woniis. wings o» the voth described. 

 ■wings are spread. It is gray, witli a black band in front, edged on its liind 

 side with an ash gray one, paler than the ground; and on the shoulder at 

 the base of the fore wings is usually a small spot of dull pale yellow. 

 The abdomen is tapering and somewhat flattened, dusky grayish, paler 

 towards its base, its tip more blunt in the male than in the female and 

 covered with a brush of hairs. The iega are blackish 'gray and hairy on 

 their undersides, the spurs at the end of the middle and hind shanks being 

 black in their middle and white at each end. The feet are five-jointed, long 

 and tapering, the first joint much the longest and the following ones suc- 

 cessively shorter. They are gray, gradually passing into black at their 

 ends, each joint having a white ring at its tip. The winga in repose are 

 laid flat, one upon the other, in a horizontal position, sometimes so closed 

 together that their opposite sides are parallel, but oftener widening back- 

 ward (as represented in figure 3), and forming a broad shallow notch at 

 their liind end. The fore wings vary in color from ash gray to dusky giaj', 

 and sometimes have a tawny reddish refluctiou. Tiieir outer edge is gray- 

 ish black, with irregular alternations of black spots having an ash gray 

 spot between them, and towards the tip are about three equidistant pale 

 gray dots. The costal area or narrow space between the outer edge and 

 the first longitudinal vein is pale ash gray, gradually becoming dull and 

 obscure beyond the middle. At the base, on the outer edge, are two black 

 spots or short transverse streaks, with a pale gray streak between them, and 

 opposite these, on the basal middle of the wing, are similar streaks placed 

 obliquely, which are frequently faded to a blackish cloud-like spot, with a 

 pale gray streak crossing its middle. Outside of the central part of the 

 wing are the stigmas, two large roundish pale gray spots, having a 

 square coal-black spot between them and a triangular one forward of 

 them. '1 he anterior one of these stigmas is broad oval, almost circular, 

 and placed obliquely, with its outer end more towards the base of the 

 wing than is the inner end. It is of a uniform pale gray color, slightly 

 paler than any other part of the wing. Its edge is well defined by the 

 black color surrounding it, except at its outer end, where it is incom- 

 plete, being confluent with the ash gray color of the costal area. 

 The hinder stigma is kidney-shaped, being concave on its hind side, 

 and occupying this concavity is a pale gray spot or cloud, quite variable 

 in its size in different specimens, and frequently taking on a buff or cream 

 yellow tinge. This stigma is brownish or watered gray, becoming paler 

 along its anterior edge, its ends, particularly the inner one, being vague 

 and indefinite, blending with the adjacent coloring, sometimes so much so 

 that only its middle portion is distinct. Between these stigmas is a large 

 square spot of a coal-black color, occupying the whole space between the 

 two midveins of the wing, its fore and hind sides made concave by the 

 rotundity of the stigmas which bound it upon these sides. Forward of the 

 anterior stigma is a second black spot of a somewhat triangular form, also 

 occupying the whole space between the two midveins at this point. On its 

 hind side it is concave and cut off obliquely by the obliquity of the stigma, 

 whereby it is prolonged along the inner vein, usually into a long acute
