Lepidoptera op New York and Neighboring States 587 



Very common, and generally distributed, sometimes injurious to stored hay. 



May to September. 



New York: Ogdensburg, Lewiston, Sherwood (Cayuga County), Ithaca, Big 

 Indian Valley, Onteora Mountain, vicinity of Albany, Rhinebeck, North Hillsdale 

 and New Windsor. 



Variety hyllalis Walker has the ground pale yellowish, the lines almost lost. 



59. HERCULIA 



(Pyralis, in part) 



Similar to typical Pyralis, except as noted in the key; M 2 and M 3 free; 3d A 

 preserved. 



Key to the species 



Outer line finely dentate, dark, far out 1. intermedialis. 



Outer line even, nearly straight, often obscure. 



Pinkish to violet-gray 2. olinalis. 



Clay-color , 3. thymetusalis. 



1. H. intermedialis Walker. Wings narrower, suggesting Aglossa. Dull red- 

 brown; terminal space distinctly redder and paler. Base pale; antemedial line 

 strongly irregular, toothed far out on Cu, and less on A; pale followed with black; 

 postmedial four-fifths way out, black, offset in to costa, and followed by a dis- 

 tinct pale patch; below, narrowly pale shaded. Hind wing paler, grayer, with 

 the faint darker inner and outer line widely separated, and the outer nearly even. 

 22 mm. . (cohortalis Grote. ) 



June and July. 



Generally distributed. New York: Mt. Marcy, Fentons (Lewis County), vicinity 

 of Buffalo, Ithaca, Hastings, New Windsor, Katonah. 



2. H. olinalis Guenee. Dark gray with more or less violet tinge, and pinkish 

 fringe, tipped with yellow; marked like H. costalis, but the lines straighter, and 

 often obscure below the costa. Outer line on hind wing hardly beyond middle of 

 wing. The ground sometimes much paler, rose pink (hirnionialis of authors, but 

 not of Zeller, who had the typical form). 22 mm. (H 47:46; 48:13.) 



June and July. 



New York: Lancaster, Peru, Ithaca, Big Indian Valley, Schenectady, New 

 Windsor, New York City; Clove Valley, Staten Island. 



Variety infimbrialis Dyar is ochreous with only a slight pinkish tinge, almost 

 as light as H. thymetusalis. It occurr in southern Massachusetts, and is probably 

 somewhat general in distribution. 



3. H. thymetusalis Walker. Simil -r to H. olinalis; pale luteous, dusted and 

 shaded with dull light gray, emphas: "ing the luteous lines on the side toward the 

 median area, where there are distinct gray lines. Lines slightly dentate; ante- 

 medial excurved, broad ; postmedial sometimes shortly interrupted, starting from 

 a triangular costal patch. Hind wing paler, the lines close together; antemedial 

 slightly irregular, and postmedial excurved. 22 mm. 



Perhaps a variety of H. olinalis, with which it seems to intergrade. 

 A northern species, ranging south to the Adirondacks. 



New York: Saranac Inn, Mt. Marcy, Fentons (Lewis County), Albany, New 

 Windsor.
