6. Front rounded out half the width of the eye, or nearly so (fig. 

 342) ; male with a blister between R, and R„ of fore wing. 



43. Autocosmia {helianthales) . 

 6. Front moderately rounded out or flat and oblique. 



7. Hind legs twice as long as body 49. Lineodes. 



7. Hind legs moderate. 36 



8. Maxillary palpi triangularly scaled, filling space between 



labials and front 48. Loxostegopsis. 



8. Maxillary palpi slender but widened by rough scaling at the 



tip; more or less triangular (rig. 335) 31. Evergestis. 



8. Maxillary palpi small and slender. 



9. Fore wing half as wide as hind wing; outer margin half as 



long as inner; M 3 and Cu x separated at margin by from 



a third to half an interspace (fig. 323) . . . .36. Nomophila. 



9. Wings proportionate, fore wing nearly as wide (fig. 324) as 



hind wing. 



10. Male with a bulla on fore wing and distorted venation. 



32. Crocidophora. 

 10. Male with fore wing pointed, much more than twice as 



long as wide 35. Stenophyea. 



10. Male with outer tibial spurs minute, at least the upper 



one 46. Phlyctsenia. 



10. Male and sometimes female with a hyaline discal spot; 



brown with falcate fore wing 44. Perispasta. 



10. Male without "sexual modification. 



11. Fore wing falcate; both wings half orange. 



45. Cindaphia. 

 11. Fore wing with marked or rounded apex. 



12. Male antennae broadly laminate. 29. Metrea. 



12. Male antennae single 47. Pyrausta. 37 



18. HYMENIA Hiibner 

 (Zinckenia Zeller) 



Palpi upturned (fig. 326) with the three segments nearly equal in length, the 

 first two well set off and broadly scaled, the third much slenderer, upturned beyond 

 vertex, smooth-scaled and acute. Male antennae somewhat thickened and obliquely 

 notched at base. Maxillary palpi long and fusiform. Fore wing with R : approxi- 

 mate to R 3W , R 5 divergent from base; M 2 and M 3 somewhat approximate, CUj well 

 separated. Hind wing with cell, measured on the costal side, hardly a third the 

 length of the wing, extending out below as usual; M, and M 3 approximate. 



Key to the species. 



A continuous white fascia from within cell to inner margin 2. faseialis. 



Median fascia starting below cell; the spot in cell separate, often obscure. 



1. perspeetalis. 



1. H. perspeetalis Hiibner (Spotted beet worm). Brown, somewhat mottled with 



ochre yellow. Fore wing with a squarish spot in cell; a weak antemedial line 



across the wing; a postmedial fascia from costa at three-fourths way to apex, 



extending a third way across the wing, with two small dots below and beyond 



36 A few members of the first group with triangular palpi, may run out here, but may 

 be distinguished from most of the following genera by R* which is curved and approxi- 

 mate to R 3+4 at base. 



37 Sameodes may run here, but differs by its close-scaled palpi with well-set-off third 

 joint.
