Lepidoptera of New York and Neighboring States 651 



fold to below end of cell, offset upward at half its length; these markings all 

 variable. (25) 30-41 mm. 



Larva in stem of Myrica. 



New Jersey; southern United States. 



15. 0. sulphureodactylus Packard. Bright sulphur, yellow, slightly tinged with 

 brown; with more or less distinct traces of the usual markings. Hind wing choco- 

 late brown, contrasting. 25 mm. (sulphureus Walsingham. ) 



September. 



Western States. Woods Hole, Massachusetts, and Hemlock Lake, New York (?). 

 The eastern specimens are undersized, and their determination not certain. 



0. inconditus Walsingham has been reported from the District of Columbia, pre- 

 sumably in error for one of the species just described. It is somewhat similar to 

 lacteodactylus, but without the dark points at the ends of the veins, and is typi- 

 cally grayer. 



II. All three feathers of hind wing linear, the third with a very broad fringe;, 

 hind tibice with upper outer spur only three-fifths as long as inner; with a small 

 tuft of hair scales a short way above them. (Pterophorus; Emmelina Tutt). 



16. 0. monodactylus Linnaeus. Pale grayish or pinkish brown (in the typical 

 form from Europe with a decided yellow tint). Fore wing sometimes with a 

 little black and white dusting; with a dark fissural spot or wedge; a dark sub- 

 terminal bar on the costa, and two smaller spots beyond it; and dark spots on 

 both feathers; all relatively slight. Hind wing and fringes normally chocolate 

 brown. 28 mm. {pterodactyla Hiibner not Linnaeus, cinereidactylus Fitch, per- 

 gracilidactylus Packard, etc. ) . 



Caterpillar on Convolvulus and several other herbs. Bright yellowish green; 

 head pale yellow. A narrow dorsal and broader stigmatal yellowish white stripe. 

 Hairs grayish, in tufts from tubercles. Under side paler. Pupa green with 

 blackish brown dorsal and lateral lines, and streaks on wing-cases; head flattened, 

 hairy, marked with brown; part of dorsal hairs blackish. 



Nearly world-wide, but running to well marked local forms. New York: 

 Wilmington, vicinity of Buffalo, Ithaca, Schenectady, Albany. 



7. ADAINA Tutt 

 (Pterophorus, Alucita, (Edematophorus, in part) 



Similar to Oidsematophorus, but with R, and R 4 stalked. Tibiae not tufted, wings, 

 on the average, narrower. 



Neither of our species is typical of the genus, and they should perhaps be 

 restored to Oidsematophorus. In the typical species the larva is a borer, with 

 simple hair, except for a couple of extra hairs associated with seta vi; our species 

 agree - with those of Oidsematophorus. 



1. A. montana Walsingham. White, lightly dusted with brown, the dusting 

 gathering into a bar at end of cell, and a subterminal shade on costa. Fringe 

 white, cut with brown below apex of first feather, and above apex of second. 

 Hind wing browner. 16 mm. 



July. Caterpillar on leaves of Solidago, full-grown in June. Pale green with 

 a triple fine white dorsal stripe, and " seventh to ninth rings " yellow. Tubercle 

 i with one hair, ii with two, iv and v as warts. Pupa green, sometimes with a red 

 dorsal stripe; suspended. The egg hibernates. 



California. New York: Buffalo. 



A. declivis Meyrick is considered by Barnes and Lindsey to be a variety of 

 montana. Moth somewhat darker, shaded with brown dusting, and with more 

 fully developed brown markings.
