Two specimens in my collection. Its nearest allies are defectella 

 and genieulatella, from both of which the present species differs by 

 its leaden -gray color and the median band not angulated externally. 



T. gtMiiculatella n. sp. — Palpi sordid white, labials above and beneath 

 dark brown, dusted with fuscous, terminal joint rather short, basal half dark 

 fuscous. Head sordid white. Antennae pale fuscous. Thorax grayish white, 

 patagia fuscous in front. Forewings moderately wide, creamy white, markings 

 blackish brown ; a heavy costal streak on basal fourth ; a heavy spot at middle of 

 costa, extending less than one-half the wing breadth, where it is joined by a 

 curved line beginning at two-fifths of dorsal margin and forming an acutely an- 

 gulated fascia, from its angle extends a streak towards end of disc, beyond the 

 fascia are two small costal dots, and just before the apex two large spots, more or 

 less coalescent, and opposite to these a spot on the dorsal margin ; a few smaller 

 dots along base of dorsal cilia and a distinct spot at end of disc; some scattered 

 brown scales, especially in apical part of wing. Cilia sordid whitish, with scat- 

 tered fuscous scales. Hind wings under 1, grayish fuscous, cilia dark fuscous at 

 their base, becoming ochreous gray outwardly. Legs ochreous fuscous. Legs 

 grayish ochreous, dusted and spotted with fuscous. 



Exp. 15.0-17.0 mm.; 0.6-0.64 inch. 



Hub. — California (Pasadena, Occidental, Kaweah). 



Three specimens in my collection from the three mentioned local- 

 ities. A specimen sent to Lord Walsingham for identification was 

 returned as T. arcella, from which, however, it differs by the dorsal 

 spot further removed from the base, a spot at end of cell and a dis- 

 tinct dorsal spot before the apex. 



T. arcella Fab.— PI. II, fig. 6.— Dyar's List, p. 573, No. 6531.— Palpi ochre- 

 ous white, labials fuscous externally, except at the apex. Head white. Antennae 

 ochreous white. Thorax white, edged anteriorly with fuscous. Forewings white, 

 somewhat suffused with pale, cream-yellow; markings dark brown, a heavy 

 streak on basal fourth of costa, a large subquadrate costal spot just beyond the 

 middle somewhat oblique outwardly and forming with the dorsal spot a sharply 

 angulated fascia, more or less entire, the dorsal spot almost triangular, just be- 

 fore the middle slightly curved, with its widest part resting on the margin, the 

 apex pointing obliquely outwardly ; a costal spot, sometimes wanting, just before 

 and including the apex, some irregular dots along dorsal margin ; the white sur- 

 face sometimes sprinkled with pale brown scales. Cilia white, fuscous corres- 

 pondingly with marginal spots; underside of wing pale fuscous. Hind wings 

 under 1, grayish, dusted with fuscous towards the apex. Abdomen above ochre- 

 ous fuscous; underside of body and legs pale ochreous white, tinged with fuscous. 



Exp. 11.0-14.0 mm.; 0.44-0.56 inch. 



Hab. — Europe, Pennsylvania (Hazleton) ; New York (Ithaca) ; 

 District of ( Jolumbia, Ohio (Cincinnati) ; Maryland Plummers Is].). 



A specimen in my collection has the wings infuscate, the brown 

 scales being arranged in irregular transverse lines.
