the costal margin, the last of which is placed at the beginning of the cilia, and a 

 row of brown spots extends at the base of the cilia, entirely around the apex; 

 there is a dark brown spot on the middle of the disc and another at the end of 

 the disc. Cilia and hindwings silvery pale gray. Abdomen brown, the apex sil- 

 very. The first pair of legs is brown on the anterior surface, and the tarsi are 

 annulate with white. Middle and hind legs silvery gray. Al. ex. -A inch. Ken- 

 tucky." 



The above is Mr. Chambers' description. A specimen is in the 

 National Museum Collection. Mr. Busck informs me that it is a 

 narrow winged species, hindwings under 1. T. macu/imarginella 

 Ch. does not appear to differ from this species. 



T. fnscopulTella Ch.— PL II, fig. 1.— Dyar's List, p. 571, No. 6505.— 

 "Snowy white; outer surface of the labial palpi dark brown; antenna sordid 

 yellowish white; thorax and primaries dusted irregularly with dark brown 

 scales, the dusting sparse in some portions, but in others aggregated into small 

 spots or patches, a small one of which is on the fold not far from the base; two 

 other larger ones about the middle and others in the apical half of the wing; it 

 also assumes the form of more or less distinct costal and dorsal streaks. Al. ex. 

 three-sixteenths inch. Kentucky." 



Not known to me in nature, and while, to judge from the descrip- 

 tion, the present species seems closely allied to nigroatomella, they 

 could not, by any stretch of the imagination, be considered identical. 



T. nigroatomella n. sp. — PI. Ill, fig. 4. — Palpi, head and antennae sordid 

 yellowish white. Labial palpi rather long and slender, slightly dusted with fus- 

 cous externally. Autennre faintly annulate with pale brown. Forewings mod- 

 erately elongate, pointed, white, profusely speckled with dark brown scales, 

 aggregated into ill-defined spots and two ill-defined fascias, the first of these is 

 at one-third the wind length, slightly curved outward and equidistant from the 

 base at both margins; the secoud fascia begins at the middle of the costal margin 

 and extends obliquely to the beginning of the dorsal cilia; a small costal spot 

 near the base and a dorsal spot behind the anal angle, three or four costal spots 

 in apical part of wing, becoming larger outwardly; an ill-defined spot at end of 

 cell ; tbe apical part of wing more densely sprinkled. Cilia whitish, several dark 

 bars in costal portion, corresponding with the marginal spots, dorsal cilia sprink- 

 led with fuscous scales, which form an irregular, post median dividing line. 

 Hindwings under 1, pale gray, cilia concolorous. Underside of body and legs 

 yellowish white, feebly spotted or tinged with fuscous. 



Exp. 8.5 mm.; 0.26 inch. 



Hab. — New Jersey (Montclair). 



A specimen in my collection, kindly given me by Mr. W. D. 

 Kearfott. Very closely related to fmcopulvella.
