Genus GAEIDES, Scudder. 

 EDITH'S COPPER, Goeides editha Mead. Fig. 98. 



Fig. 98. Gaides editha. 



Butterfly— Expanse, 1.25 to 1.35 inches (31 to 34 mm.) Male fuscous 

 above, narrowly edged with black along the outer margin, and with black 

 discal bar; the usual spots show through very faintly on the upper side. 

 Hind wings fuscous, with similar black edge, and within this a row of 

 four or five black spots near the anal angle. The two nearest this angle 

 are surrounded by an irregular ochraceous line. Under side of fore wings 

 gray inclining to fuscous, cinereous on the disc, with the black spots as 

 allied species. Hind wings below gray-fuscous clouded with white. A 

 rather broad band of gray-fuscous occupies the outer margin; this band 

 is crenated inwardly and cut by a fulvous line which begins on the 

 abdominal margin, extends out on the submedian and last branch of 

 median nervules, thus leaving a white, black pupiled half.ocellus at anal 

 angle, a large gray-fuscous crescent in the next interspace, and next to 

 this a white, black-pupiled ocellus; in this respect the present species 

 resembles Xanthoides and differs from Dione, which has much more ful- 

 vous. At the inner edge of the gray-fuscous band the white clouding is 

 condensed into a continuous line of broad lunules, and at the inner border 

 of this is the row of spots always fouund in this genus; these spots are 

 quite large, pale gray-fuscous, edged with black and surrounded by white; 

 the discal bar is usually confluent with the dot within the cell, so as to 

 form an irregular horse-shoe mark. 



Fringes of all the wings composed of scales of two lengths, the upper 

 and shorter set being nearly black, the lower ones white; sometimes the 

 black scales are a little longer in certain places, thus making the fringe 

 seem white cut with black. 



The last branch of median nervule of hind wings prolonged into a very 

 slight tooth; this is more distinct in the female ,being there about as in 

 Xanthoides, male. 



The female differs from the male in always having at least a small 

 fulvous or ochraceous cloud upon the disc of fore wing, and a similarly 

 colored streak at the outer angle. The cloud upon the disc is some- 

 times so extended as to cover half the surface of the wing. The spots of 

 lower surface are rather distinctly shown above. In the middle of second- 

 aries there is often an iroration of fulvous scales and a distinct scalloped 

 fulvous line along the outer margin, enclosing a black crescent, or double 

 dot near anal angle and smaller dots above.
