K'emai-kaiile (()r its immense liushy [)al[)i, in the plumose antenn;e and 

 shape ol' wings it resembles Ematurga Fa.ro/ii/. Tin; hairy iiody, the blackish- 

 ash fore wings, and bright reddish-orange hind wings and lunivily-cdieekered 

 fringe, and, beneath, the orange fore wings and pepper-ancKsalt Iiind wings, 

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

 nie. 



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

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

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

 the hinder pair, this being sometimes reduced to a narrow l)lack line. In 

 one ca,se, the discal dot is confused with the inner line on the hind wine. 



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



Male antennfe not pectinated, but with heavy cilia?; 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 obliipie than usual. Venation much as in Selidosema, 

 the costal vein anastomo.sing with the subcostal; no subcostal cell ; second 

 subcostal venule thrown ofT from the finst; discal venules very oblifjue. Hind 

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

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

 brown flecks and s])ots. 



The genus difl'ers much from Fidonia in the ciliated antenna' and rectan- 

 gular apex of the l()re wings, while the venation is like that oJ' Selido.semu.
