AMERICAN LEPIDOPTERA. 63 



T. auropulvella Ch. — Dyar's List, p. 570, No. 6491, synj. 

 Mr. Chambers describes the species as follows : 



"Snowy white, outer surface of the second joint of the labial palpi brown ; an- 

 tennae yellowish white; primaries very sparsely dusted with pale reddish or 

 brownish golden, except in the apical portion, where the dusting is rather dense» 

 is also thicker near the base of the dorsal margin. A dark brown spot on the 

 costa at the extreme base, another large one on the costa near the base ; a smaller 

 costal one just before the middle ; a large one just behind the middle reaching to 

 the fold, another small one before the cilia, and five or six small ones extending 

 around the apex at the beginning of the cilia; in some lights these spots are dis- 

 tinctly golden brown. Al. ex. seven-sixteenths. Kentucky." 



This species has been referred to in our lists as a synonym of 

 acapnopennella, from which it is quite distinct ; among Chambers' 

 "types" in Cambridge are three specimens of acapnopennella, thus 

 showing that the author did not notice the difference or failed to 

 recognize Clemens' species, which is excusable. Some of Chambers' 

 statements in the description are rather misleading, the large spot 

 just beyond the middle, is quadrate and rarely extends beyond one- 

 half the wing breadth ; an inconspicuous spot on the dorsal margin 

 at one fourth, and from which extends a line, more or less interrup- 

 ted, to the large costal spot; another dorsal spot at beginning of 

 dorsal cilia; the dots along base of cilia are frequently forming a 

 continuous line, here and there interrupted ; cilia white, tinted with 

 reddish golden, with a distinct dividing line beyond their middle 

 and a less distinct dark edge, barred with darker lines, preceding 

 from the costal spots. A dark spot on the patagia in front. Hind- 

 wings under 1, pale grayish fuscous. Legs yellowish white; tarsi 

 spotted with fuscous. Exp. 11.5-16.-0 mm.; 0.48-0.64 inch. 



Hab. — Kentucky, New York, New Jersey, Pennsylvania (Hazle- 

 ton ). Auropulvella differs essentially from acapnopennella by its 

 narrower and more pointed wings, its more pronounced markings 

 and golden lustre and lacks the spot at end of cell. 



T. acapnopennella Clem. — Dyar's List, p. 570, No. 8513.--11 cad white. 

 or ochreous white, intermixed with fuscous. Palpi yellowish, labials dusted ex- 

 ternally with brownish scales. Antennas pale ochreous, finely annulate with 

 brown. Thorax sordid white, speckled with brown scales, patagia brown in front. 

 Forewings rather broad, a dull white, sprinkled with pale brown scales in vary- 

 ing density and forming at times irregular transverse lines, or else giving a more 

 suffused appearance; the markings are brown; basal part of extreme costa, an 

 oblique spot near the base reaching to the fold, a somewhat smaller spot at one- 

 fourth, beyond the middle is a large suhquadrate spot and opposite to it at I In- 

 beginning of dorsal cilia, a smaller one, a regularly curved fascia, with the con-
