side of fore wing with scattered light fuscous flecks, and a broken black terminal 

 line. 19 mm. 



The only specimen before me was taken in April. 



New York : Ithaca. 



11. A. nigrinotella Busck. Palpi light yellow -brown, the base black-shaded and 

 extreme tip black. Head light red-brown, thorax yellow-brown, — the front, 

 back, and tegulae darker. Base and basal half of costa yellow-brown, the rest 

 of the wing brownish fuscous, with scattered black scales. Discal dot d only. 

 white-scaled. Hind wing shining light yellowish fuscous. 22 mm.

 Ohio; Illinois.

 paler base followed by a dark shade. Costa interrupted with black and yellowish. 

 22 mm. 



This form is easily distinguished from the other red species by the lack of 

 white discal dots. The locality was not reported, and the species is very prob- 

 ably western. 



13. A. curvilineella Beutenmiiller. Head white, the fore wing grayish white, 

 shaded and mottled with pale pearl gray, with a more or less distinct pink tint, 

 leaving the base and costa pale, the wing lightly dusted with black scales, which 

 gather into larger black spots along the costa; first three discal dots fused into 

 a black crescent, concave upward, the fourth one white, ringed with black. Hind 

 wing also pale, with white fringe. 18 mm. 



October to April. 



New York to Missouri. Xew York: Ithaca, New York City. 



14. A. hyperella Ely. Similar to A. curvilineella; most of the wing-surface 

 nearly evenly mouse-gray. Vertex dark gray, unlike even the darkest specimens of 

 A. curvilineella. 16 mm. 



End of May. Larva on Hypericum prolificum in April. Possibly a seasonal 

 form of the preceding species, which however appears to be single-brooded in the 

 north. 



Great Falls, Virginia. 



15. A. senecionella Busck. Luteous, slightly shaded with pink, and strongly and 

 irregularly with dull gray, leaving the base pale and sharply defined except at 

 costa. Paler areas also over the discal dots a and b and beyond d, and a vague, 

 paler postmedial line. Third discal dot not distinct. Ground sometimes more 

 evenly gray. Hind wing pale gray, the veins darkest. 17 mm. 



Larva in March; imago in May. 

 Plummer's Island, Maryland. 



A. canadensis Busck, which is slightlv more dusted with black, and has the 

 base of the hind wing paler, is likely to occur in the west of our area. 



16. A. lythrella Walsingham. Tawny reddish, heavily shaded with mouse gray 

 and dusted with black and pale cinereous toward costa; a distinct dark spot in 

 the dorsal part of the whitish base, normally nearly covering the pale area; a

 group of whitish-cinereous scales. Discal dot d represented by a vertical white 

 bar. Terminal line continuous, fading out at apex. Fringe purplish gray. Hind 

 wings mouse gray. 1& mm. 



Caterpillar on Ly thrum alatum. Dull whitish green, immaculate; webbing the 

 leaves in June. Moth in July. 

 Illinois; North Carolina. 



17. A. flavicomella Engel. Straw yellow, shaded with red-brown and flecked 

 and obscurely striate with blackish or umber brown. Outer discal dot black, in 

 a brown spot or shade; inner (b) a black point, or obscure; more or less distinct
