the bead; scales loose and long. Antennae moderately pectinated; the 

 branches shorl and very slender, shorter than in Perconia; in female simple. 

 Fore wings with the costa straight, a little sinuous, the apex a little more 

 produced than in Ematurga; outer edge more oblique than in Ematurga. 

 Hind wings with the outer edge full, slightly benl on the first median vein, 

 and with a slight sinus below (lie apex, which is round, not produced as ill 

 Emaiurga and Perconia. Venation much as in Ematurga, but the subcostal 

 areole is open; the areole is, however, narrow and curved, as in Ematurga. 

 The costal vein joins the areole either before the middle and unites with it 

 to near the end, as in F. truncataria, or joins it (in F. carbovaria of Europe 

 much as in Ematurga, bu1 a little beyond the middle. Hind legs as in Ema- 

 turga; the tibise being slightly swollen, and the tarsi nearly as long as the 

 tibiae. Coloration much as in Ematurga. 



This genus, which i would restrict to Fidonia truncataria of this country 

 and F. carbonari-a and F concordaria of Europe, differs from Ematurga in the 

 subcostal areole being open, in the short branches of the antennae, anil the 

 more rounded hind wings. From Perconia it differs in the more pointed 

 apex of the fore wings, and the shorter, squarer, hind wings, and the narrower 

 costal area of the fore wings, with the narrow but open areole, and the Hat 

 clypeus. The species are of small size.

8 d and 1 9. — Antennae with pectinations less than half as long as in P. 

 fimetaria. Fore wings more acute; apex rectangular, not rounded; hind 

 wings a little produced toward the apex, and distinctly notched in the outer 

 edge. Palpi much larger than in P. jimelaria, projecting well beyond the 

 head. Body and wings deep rusty orange-ochreous as a ground-color. 

 Head and palpi more red than the thorax. Fore wings with four, well-marked, 

 black, irregular, equidistanl hands; the basal one curved outward a little; the 

 other three straight, though a little sinuous in their course; the two outer 

 are edged extern alh with a whitish streak; a black linear marginal line. The 

 spaces between tin- lines are marked with linear dots. The discal dot large 

 and round, sometimes contused with the transverse strigae and extradiscal 

 hand. Hind wings like the fore wings, with three broad, irregular, black
