32. C. luteolellus Clemens. Pale ochre yellow, marked with tawny brown; the 

 markings exactly as in caliginosellus, but weaker, and often nearly obsolete. 

 Fringe pale brown, not shining. Valves more slender than in caliginosellus and 

 zeellus. 23 mm. 



Common and generally distributed. New York : Peru, Newcomb, Ithaca, Little 

 Falls, Katona-h. 



The variety ulaa Cockerell, from Colorado and Arizona, is much more contrasty, 

 and has black terminal dots. 



II. Eyes half as wide as front, or slightly less; palpi very hairy; venation as in 



the first group. 



33. C. trichostomus Christoph. Powdery dull light gray; head and thorax 

 blackish ; a broad oblique blackish antemedial band from middle of costa to a 

 third way out on inner margin, followed by a white shade; a similar, but usually 

 narrower, subterminal band, roughly parallel to the outer margin, but sinuate 

 below the costa, followed by a stronger white shade. Terminal line practically 

 continuous, heavy, black; fringe gray, cut with white. Hind wing slightly 

 browner. 20 mm. 



Labrador. 



70. RAPHIPTERA Hampson 



(Crambus, in part) 



Similar to Crambus; R t lost and Rg and R 4 completely fused, also M 2 and M 3 , 

 leaving no stalked veins in the fore wing. Hind wing with M 2 and M 3 completely 

 fused; fore wing strongly falcate. 



1. R. minimella Robinson. Mouse gray; cell white, slightly silvery, the streak 

 ending in a point five-sixths way to apex, with a white chevron over its apex, and 

 a triangular patch running to tip of wing; costa shaded with luteous as far as 

 the postmedial line; postmedial line oblique outward to opposite cell, then brown, 

 nearly even and parallel to outer margin, across to the inner margin. Hind wing 

 fuscous, sometimes pale at base. 12 mm. 



Southern States and Illinois. 



2. R. argillaceellus Packard. Similar, slightly larger; costal region not con- 

 trastingly pale, there being strong dark stripes both above and below R, the 

 lower one noticeably narrowing the stria in the cell. 10-15 mm. 



This is probably a northern race of R. minimellus.

Subfamily EPIPASCHIIN.& 



Antennal socket more or less completely surrounded by scales, in the type 

 genus with a wide gap on the lower side of the circle, leaving the socket in 

 contact with the eye, but more often with the antenna and eye wholly separated 

 by a scaled area. Ocelli present; antennse normally fasciculate in male, often with 

 a long plume-like process on scape. Labial palpi large, upturned, in many males 

 hollowed out, and enclosing the plume-like maxillary palpi. Maxillary palpi 

 of females and of a few males normal, somewhat ti'iangularly scaled; always 

 well developed. Tongue developed. Fore wing with R x free, R 5 stalked with 

 R 3 and R 4 . Male often with fovea and distorted venation; 1st A absent; 3d A 

 free and weak. Frenulum simple in both sexes. Hind wing with Sc and R 

 approximate or anastomosing; M t from near upper angle of cell; cell distinctly
