June, I902.] KeARFOTT : On NoRTH AMERICAN ChOREUTES. 120 



joined K.o pretiosana Dup., by Staudinger. Zeller regarded these two European spe- 

 cies as distinct at the time when he identified specimens from Texas and Ohio as/rt"- 

 tiosana, and his specimens, now before me, are certainly nearer to this than to the 

 typical hjei-kandrella, but I now see differences which may possibly be of special value 

 in all of the American species. 



"Your two New York examples are nearer to pretiosana Dup. {= ausiralis Z. ) 

 the South European form, but they differ in having no markings on the under side of 

 the fore wings, and in the presence of a small metallic spot above the dorsum on the 

 inner edge of the first pale sprinkled band near the base. This occurs also in Zel- 

 ler' s and Murtfeldt's specimens, but not in the European forms. I think your two 

 New York examples are distinct from all with which I am acquainted. Notably, in 

 the absence of a distinct pale streak on the upper side of the hind wings. As you 

 have compared it with American types you are probably justified in separating it. I 

 send you two specimens of silphiella Grote. It seems to me rather a stretch of imag- 

 ination to lump this with bjerkandrella.^'' 



Choreutis busckiella, sp. nov. 



Dark brown, heavily overlaid with whitish scales, with only a trace of ochreous. 



Antennae brown, ringed with white. Palpi brown, whitish at base. Head and 

 thorax brown, dusted with white, no ochreous scales, a few silvery metallic scales along 

 lower edge of patagia. 



Basal area dark brown, a faint streak of ochreous below costa, in some specimens 

 no trace of ochreous, costa at base black, overlaid with metallic scales ; a wide dark 

 brown band beginning at costa extends downward half and then at right angles to hind 

 angle. On the lower end of this band is the usual velvety black patch ; in this species 

 it is large and almost rectangular, cut near its lower end by a double line of dark 

 brown ; between this dark band and basal area as well as the balance of fore wing is 

 of ground color heavily overlaid with whitish. 



Metallic scales occur : a line on costa near base, a short line below on median 

 line and a few scales below this near hind margin ; on first white band, a line of 

 scales extending from costa nearly to hind margin just beyond first third, this line 

 interrupted twice and curving slightly outward at lower end ; three small spots in 

 oblique line from costa on dark brown patch, below this is short horizontal line ; a 

 line of scales beginning at costa outer third and following margin around apex and 

 outer margin to hind angle, interrupted once above and once below apex. Fringe 

 brown. 



Hind wings grayish-brown, a short curved line of whitish scales about center of 

 outer margin and a few scattered whitish scales at apex. Fringe brown. 



Under side fore wings immaculate, fuscous. Under side hind wings fuscous, nar- 

 row band whitish, parallel to outer margin, a shorter whitish line within this, and a 

 short dash about center of wing. 



Abdomen brown, under side whitish. Under side thorax white. Legs brown, 

 sprinkled with white. Expanse, 12 to 13 mm. 



Three specimens, Hastings, Florida. (A. J. Brown), March 15 

 and 16.
