aiid subacutely scalloped between the venules much as usual; the band is 

 hall ;i?- wide on the inner edge as on the costa. Fringe on both wings with 

 a faint median line. Hind wings smoky, with two transverse, parallel, dusky 

 lines. Beneath much as usual, being smoky-ash, with two dusky bands on 

 both wings beyond the middle, broadest and darkest on costa, less curved 

 and farther apart, and farther from outer edge than usual. A faint discal 

 dot, better marked on hind wings. Abdomen and legs nearly concolorous 

 with hind wings. 



Length of body, 0.52; of tore wing, 0.67 inch.

2 <?. — This is by far the largest and most showy species of this genus 

 yet known to us. Body pale-ash, with a luteous tinge; palpi long, brown. 

 Fore wings pale-green, arranged in broad bands, alternating with equally 

 broad, blackish bands, varying as usual in width. The green band in the 

 middle of the wing is partly or almost wholly white. Six unusually distinct 

 black bands; the insertion of wing black; the first band beyond very narrow, 

 and bent outward on the median vein ; the second very broad and more 

 regular than those beyond, bent outward at right angles in the discal space; 

 the whitish line is edged on each side by blackish, interrupted lines, the spots 

 varying much in size. The submarginal band also dislocated, and very irregu- 

 lar, bordered internally with whitish ;. this band is merged toward the apex 

 with the marginal band, consisting of a row of triangular spots. Fringe 

 dark brown. Beneath, costa paler than rest of wing, with five large, square, 

 dark brown, conspicuous spots. Hind wings smoky-gray beneath, with two 

 broad, submarginal, dusky bands. 



Length of body (not including palpi), cf,0.54; of fore wing, 9,0.73; 

 expanse of wings, 1.40 inches.

This showy species may be identified by the black and green bands on 

 the fore wings, the more or less whitish central band, and by the large, square, 

 costal spots on the underside. In one specimen, the margin of the fore wing 

 is almost wholly black, with a short vein of whitish-green spots.
