13. H. elyella Dietz. White, lightly powdered with black; black dashes near 

 base below Sc, and in fork of A, orbicular and discal dots horizontally elliptical, 

 contrasting, black; a blackish shade in fold below orbicular, and one before it 

 near costa; some dark gray shading outwardly near margin. Usually with dis- 

 tinct dashes between the radial veinlets beyond orbicular and upper discal dot.

14. H. subsenella Zeller (as determined in United States National Museum).

The following species of Holcocera are wholly unknown to me; some may be 

 synonyms. 



H. modestella Clemens. Ground even, fuscous; basal part of fore wing paler and 

 grayer; a dark fuscous orbicular and two discal dots. The outer boundary of the 

 pale base angled out but not reaching the orbicular (group II). 16 mm. 



Atlantic States. 



H. inclusa Dietz. Similar to H. modestella; gray with paler base, and excurved 

 antemedial fascia not reaching orbicular, but without antennal notch. No dot 

 outward on Cu. Ground nearly white, but heavily overlaid with gray; no basal 

 dashes. 15 mm.
