translucent yellow, with marginal third brown. Anal tuft yellow and brown. 

 30 mm. (H 47:43.) 



August. Larva in stems and fruit of the melon family. 



Massachusetts to Missouri and south to the tropics. New York: Albany. 



2. E. hyalinata Linnaeus. White. Costa with an even black-brown band reach- 

 ing inner margin at base, and covering cell; outer margin with an equally 

 broad band; hind wing with blackish band evenly tapering to anal angle, the 

 fringe whitish. Tuft of male black and yellow (in aberration niveocilia Hampson 

 wholly black). 28 mm. (H 47:39.) 



Larva with E. nitidalis; sometimes injurious. 



Quebec to Colorado and south. New York: Buffalo, Brooklyn. 



3. E. quadristigmalis Guenee. Almost transparent; white, costa brown above R; 

 two black discal dots, and one representing orbicular, rarely absent. Tuft white. 

 25 mm. (H p. 394 f. 217.) 



Not rare. 



Quebec to Colorado and south. New York: Ithaca, New Windsor. 



28. CONDYLORRHIZA Lederer 



Similar to Eudioptis; palpi beaklike, the third joint rather long and lying along 

 the upper face of the second, reaching its tip. 



Perhaps E. quadristigmalis would be better transferred to this genus. 



1. C. vestigialis Guenee. Typically very pale brown; in variety tritealis Walker, 

 translucent light lemon yellow, with lines brown; antemedial strongly oblique out 

 toward inner margin; orbicular a dot, reniform a short bar. Postmedial line 

 strongly excurved at middle, sinuous, bent at a right angle below cell, and then 

 ending perpendicular to inner margin. Terminal line and fringe brown. Hind wing 

 concolorous, with discal bar, an irregular postmedial line, and partly fused sub- 

 terminal and terminal lines, most distinctly separate toward costa. Anal tuft 

 fanlike, black. 30 mm. 



Larva on willow. 



Subtropical, straying in late fall north to New York and western Pennsylvania. 

 New York: Ithaca. 



29. METREA Grote 



Palpi upturned and not very broadly scaled, with porrect third joint, smoother 

 than usual in Pyrausta; maxillary palpi filiform; venation normal, R 5 divergent; 

 wings more rounded than usual. 



1. M. ostreonalis Grote. White, a little translucent, especially the hind wing. 

 Fore wing with a diffuse dark gray patch at end of cell (rarely absent) enclosing 

 a diffuse blackish discal dot. Two large, partly confluent, obliquely placed gray 

 patches in fold and below A, below end of cell; a gray subterminal shade below 

 M 1; resting on inner margin. 30 mm. 



July. Rare. 



Quebec to Connecticut and western Pennsylvania. New York: Peru (Everett). 



30. HELLTJLA Guenee 

 (Cabbage web-worms) 



Palpi obliquely upturned (fig. 336), the first two joints marked, the third fairly 

 long, closely scaled, oblique, well set off; maxillary palpi filiform. Venation nor- 

 mal, the veins well spaced; the scales on the discal bar very slightly raised, and 

 often slightly metallic. 



The species are not well understood. 



1. H. undalis Fabricius. Pale luteous, usually heavily shaded with fuscous; 

 lines white, wavy, defined with blackish; basal line fragmentary; antemedial com-
