Lepidoptera of New York and Neighboring States 561 



streaked on the veins and more or less suffused with pale brown; no transverse 

 markings, not even terminal dots. Hind wing yellowish, unmarked. 25 mm. 

 ( venalis Grote ) . 



June to August. 



Quebec to Wisconsin, south to southern New Jersey and Colorado. New York : 

 vicinity of Buffalo, Potter Swamp (Yates Coxinty)', Ithaca, Karner, Nassau, New 

 Windsor. 



3. P. terrealis Treitschke. Palpi as long as head. Pale fuscous, heavily pow- 

 dered on a luteous ground; markings darker, faintly defined with pale, diffuse, 

 obscure. Antemedial line excurved, postmedial sinuous, running in to below the 

 cell at Cu and then obliquely into inner margin at two-thirds way to hind angle; 

 orbicular a vague dot, reniform a dark bar. Hind wing paler and translucent, 

 except at margin, with diffuse darker postmedial line. A distinct gray ter- 

 minal line and two dark lines in fringe on both wings. 25 mm. 



Two broods, flying mainly in May and August. Larva green, with black- 

 dotted head and small black tubercles; on Solidago. 



Quebec, south to northern New Jersey, west to British Columbia and Cali- 

 fornia; Europe. New York: Peru, North Creek, Lancaster, Jamestown, Crosby 

 (Yates County), Ithaca, Big Indian Valley, Onteora Mountain, Fort Edward, 

 Schenectady, Rhinebeck, New Windsor. 



4. P. extricalis Guenee. Cream color, dusted with dull brick-red, more coarsely 

 than in P. terrealis. Antemedial line dentate, postmedial deeply and sharply 

 dentate, drawn in below cell on Cu 2 , as usual. Subterminal absent. Orbicular an 

 obscure point, and reniform a vague lunule. Hind wing similar, postmedial line 

 far out across ixL to Cu,, as usual in the obscure Pyraustas; nearer outer margin 

 than end of cell, then sharply angled in at Cu 2 ; usually strongly dentate; often 

 distinct only opposite the end of the cell. 25 mm. {dionalis Walker, oppilalis 

 Grote ) . 



May and June; July; September. Larva a leaf roller on alder. 



Generally distributed. New York : Peru, Newcomb, Big Indian Valley, 

 Schenectady. 



The coarser, less regular dusting, obvious to the naked eye, will distinguish this 

 species from P. terrealis. and theseusalis. 



4 1 /o. P. helvalis Walker. Similar to P. extricalis; normally more powdery, 

 rougher looking, with orbicular a ring and reniform at least a double bar; hind 

 wing paler, with more dentate postmedial line. 



This species is only certainly distinguishable from extricalis on genitalic char- 

 acters, and I am not at all sure I have credited the various New York records to 

 the right species. Both tend to be redder in the southern part of their range and 

 grayer in the north. The caterpillar of helvalis is a leaf roller on poplar, emerging 

 in July. 



Nova Scotia to Missouri. New York : Black Brook, Ithaca, Neversink. 



5. P. theseusalis Walker. Palpi exceptionally short. Wings dull ochreous, 

 shaded with dull light brown, or, more often, almost wholly light brown, except 

 narrowly beyond the postmedial line. Lines contrasting, hardly diffuse, dark 

 brown, antemedial excurved, practically even; postmedial waved and sinuous; 

 orbicular a dot, and reniform a brown bar. Terminal line continuous. Hind wing 

 similar. Discal dot of hind wing below obscure. 25 mm. (feudalis Grote). 



July. Larva rolling the tips' of various ferns, in June. 



General in distribution; Canada to Florida. New York: Mt. Marcy, Lewis 

 County, Lewiston, Ithaca, Karner, Rhinebeck, Katonah, New Windsor. 



6. P. tertialis Guenee. Pale straw yellow or luteous, marked with dull brown: 

 lines single, contrasting, brown; antemedial excurved, postmedial sinuous and 

 strongly bent in below end of cell, strongly dentate ; subterminal in light speci- 

 mens deeply dentate, the teeth touching the postmedial and terminal lines alter-
