vexity outward, extends from the costal spot, wbere it is widest to the above men- 

 tioned dorsal spot, where it ends in a point; a little beyond the postmedian cos- 

 tal spot is another quite distinct, and opposite to it, though a little nearer the 

 base, a similar dorsal spot ; a row of small dots along base of cilia ; a well-marked 

 dash in the middle of the fold, and obliquely outward and above this another 

 longitudinal dash, which ends in the costal end of the curved fascia; a line, more 

 or less distinct, connects the upper dash with the plical. and the latter with the 

 dorsal margin, giving it the appearance of a zig-zag line; a spot at end of disc, 

 beyond which is an aggregation of brown scales and some smaller marginal dots. 

 Cilia whitish, with darker lines corresponding to the marginal spots. Hindwings 

 a little narrower than the forewings, obtusely pointed, grayish fuscous, cilia gray. 

 Abdomen above ochreous fuscous; underside of body and legs ochreous, tinted 

 with fuscous. 



Exp. 11.5-14.0 mm.; 0.46-0.56 inch.

The description of this species by Dr. Clemens is defective; the 

 type, as stated by the author, being "slightly worn." As, however, 

 the latter is still extant in the Academy of Natural Sciences, Phila- 

 delphia, and has been carefully compared with a perfect specimen 

 in my collection — the identification is fully established. The mark- 

 ings appeal' to vary in extent. A specimen collected by Mr. A. 

 Busck on Plummers Island, and sent me for study, differs markedly 

 by its pure white forewings and the more intense dark markings, 

 the thorax more distinctly speckled with fuscous, and the second 

 joint of the labial palpi is ciliated with blackish hairs. Tinea mi- 

 nutipulnella Cli.,the type of which I have examined in Cambridge, 

 is a worn specimen of the species under consideration. 



T. defectella Zell.— Dyar's List, p. 571, No. 6501.— Palpi yellowish white ; 

 labials finely dusted with pale brown. Thorax white, a dark spot each side an- 

 teriorly. Forewings elongate, pointed, white, with blackish brown markings and 

 a feeble satiny lustre; marking as follows: extreme base of costa, oblique spot 

 near the base reaching to and becoming wider in the fold, beyond this oblique 

 spot are several smaller costal spots, a large spot on middle of costa, extending 

 obliquely backward to above the fold, where it is joined at an acute aiigle by an 

 oblique dorsal streak beginning within the margin and at one-third the wing 

 length ; beyond the large median spot are two small costal spots, in the apical 

 part of the wing is an oblique stripe, parallel to the outer margin and scalloped 

 within, a row of dots along base of dorsal cilia, a spot on the dorsal margin oppo- 

 site to the oblique costal spot near the base, another spot near anal angle. Cilia 

 white, with dark median line, costal cilia with three or four fuscous bars, the last 

 of which forms an apical spot, three or four similar bars in dorsal cilia. Hind- 

 wings under 1, pointed, gray ; cilia concolorous. Legs yellowish white, tinged 

 with fuscous. 



Exp. 12.0-15.0 mm.; 0.48-0.6 inch.
