Antenna? of female pubescent, the segments slightly angled; palpi 

 upcurved in front of face, rough-haired beneath; tongue and frenulum 

 present. 



Nturation. — Forewing; cell longer than half of wing; discocellular 

 slightl}" inangled at middle; first median nervule at seven-eighths; sec- 

 ond close before third; radials normal; 7, 8, 9 stalked, 10 and 11 from 

 cell; 10 anastomosing with 11, and again with 8. 9; hindwing, costal 

 approximating to subcostal for half of cell; 6, 7 stalked; radial from 

 center of discocellular; medians at even distance from each other. 



Type. — (yhelopteryx angusta, new species. 



The genus would. seem to be analogous to Erannis^ but the wings of

 angled on vein 6, then parallel to hind margin, approaching middle 

 line on inner margin; submarginal line pale, between two reddish 

 shades, plainest below near inner margin, a slight marginal line inter- 

 rupted at the veins; fringe pale, checkered with dark. 



Ilindicing. — Without inner line; the rest all oblique and parallel. 



Under side paler, with the lines indicated. 



Head, thorax, and abdomen like wings; face pale gray.

Locality. — Peru; 1 female.

 to vein 6, there right angled and straight to three-fifths of inner mar- 

 gin; both lines edged on each side with bluish white scales; submar- 

 ginal line irregularly dentate, formed of bluish white scales: marginal 

 line and fringe dark; some black marginal spots below apex. 



IJ!n(lw!)ig. — With the lines basal and central; the submarginal well 

 marked, strongly zigzag; the whole wing more densel}^ sprinkled with 

 bluish white scales, especially along outer and inner margins. 



Under side uniform dull brownish slate-color.
