discal spot. Beneath, the fore wings arc deep clear orange, with the border 

 of the wing all around ash-colored, speckled densely with black ; costa 

 whitish, with tour black patches. Four large black patches on the inner 

 border. Fringe heavily checkered with white and black, the black lines 

 sometimes reproduced. A distinct discal dot. Hind wings pepper-and-salt 

 colored, a little paler in the middle near the black discal spot. Under side 

 of body and legs concolorous with hind wings. 



Length of body, <?, 0.45, 9, 0.45; of fore wing, i, 0.55, 9,0.62; 

 expanse of wings, 1.06-1.34 inches. 



Nevada (Edwards) ; San Diego, Cal. (Crotch, Mus. Comp. Zool.). 



Remarkable for its immense bushy palpi, in the plumose antenna- and 

 shape of wings it resembles Ematurga Faxoriu. The hairy body, the blackish- 

 ash fore wings, and bright reddish-orange hind wings and heavily-checkered 

 fringe, and, beneath, the orange fore wings and pepper-and-salt hind wings, 

 will separate it from any American species or any European form known to 

 me. 



It varies somewhat in the degree of predominance of the ochreous- 

 orange ground-tint of the fore wings, in the presence or absence of the sub- 

 marginal white shade of the fore wings, and the width of the black border of 

 the hinder pair, this being sometimes reduced to a narrow black line. In 

 one case, the discal dot is confused with the inner line on the hind wing. 



ORTHOFIDONIA, gen. nov. Plate 2, fig. 14. 



Male antennae not pectinated, but with heavy cilise ; palpi rather bushy, 

 not very slender, projecting well beyond the front, which is not so broad as 

 long. Fore wings with the costa more convex than usual; apex rectangular, 

 outer edge much less oblique than usual. Venation much as in Selidosema, 

 the costal vein anastomosing with the subcostal ; no subcostal cell ; second 

 subcostal venule thrown off from the first; discal venules very oblique. Hind 

 wings with an almost imperceptible angle. Male abdomen slender, not very 

 long. Coloration much as in Eufidonia notataria, being white, with dark- 

 brown flecks and spots. 



The genus differs much from Fidonia in the ciliated antennae and rectan- 

 gular apex of the tore wings, while the venation is like that of Selidost ma.
