288 WILLIAM T. M. FORBES 



trapezoidal, without decided produced apex; hardly as wide as fore wing; R and 

 M! connate. Fore wing with metallic markings. 



An exotic species has been bred from a fungus bed in a termite nest. 



Key to the species 



Narrow blue dots and dashes irridipennella. 



Broad spots, and bands emblemella. 



1. S. emblemella Clemens. Fore wing brown-black, with steel-blue markings: 

 a basal band, and antemedial band from costa across cell, a very irregular, narrower 

 medial band, partly fused with the discal dot and forked toward inner margin, a 

 costal spot four-fifths way out to apex, and a subterminal band reaching two- 

 thirds way to costa and very irregular on outer side. The bands easily become dulled 

 in old specimens. 9 mm. 



June and early July. Caterpillar possibly on buckeye. 



Western New York to District of Columbia, southern Ohio, and Kentucky. New 

 York: Rock City (Cattaraugus County), Taughannock Falls (Ithaca). 



2. S. irridipennella Clemens. Shining deep brown. Fore wing marked with bright 

 iridescent blue. A strongly oblique line from costa a fourth way out across cell 

 and fold; a slightly more erect median line running into cell, and a longer one, 

 almost three-fourths way to apex. A short bar four-fifths way out and a bar 

 on inner edge near middle; the longer lines sometimes broken into dots (about 

 10 in all). 10 mm. (aphroditeella Chambers, proserpinella Frey. ) 



June to August. 



District of Columbia to Missouri. New York: Robinson Collection (presumably 

 from New York). 



13. DUVITA Busck 



(Anacampsis, Aprocerema, Untomia, in part; with Battaristis Meyrick) 



Similar to Stomopteryx and Anacampsis. Palpus with second joint smoothly 

 thickened and abruptly cut off, third slightly thickened. Fore wing normal, M! 

 not stalked, M, and Ctlj sometimes stalked, typically free. Hind wing about as 

 wide as fore wing, trapezoidal, with somewhat produced apex; R and Mj stalked, 

 M a and CUi connate, discocellular vein imperfect. Palpus shorter and hind wing 

 less produced than in Stomopteryx. Fore wing in all our species with a black 

 dot immediately below the apex as in Epitheotis subsimella. 



Key to the species 



Deep rust-red, banded with gray 1. vittella. 



White shaded with luteous 2. nigratomeUa. 



Light fuscous. 



A straight, oblique, white postmedial line 3. concinusella. 



A curved, and often obscure, postmedial line 5. oonclusella. 



Dark smoky gray 4. taha-vusella. 



I. Ape of hind wing strongly produced (Duvita). 



1. D. vittella Busck. Palpus with second joint black-brown outwardly, tipped 

 with white; third whitish with broad black annulus; head and thorax whitish 

 fuscous; face pale. Fore wing bright brown with white bands, strongly dusted 

 with steel gray, much as in Paralechia pinifoliella, but without tufts; basal half 

 of costal edge dark brown; two transverse gray and white fasciae, the median 

 one strong, denned on basal side; outer margin and apex also gray and white,
