on costa beyond middle, white along costa outwardly and at apex, with a brown 

 costo-apical spot. Fringe pale. 12 mm. (rar/atioella Chambers.) 



May. Caterpillar in a brownish frass-tube 1 mm. in diameter and 1 centimeter 

 long, along a vein on under side of leaf of sweet gum, skeletonizing leaf about the 

 ends of the tube. Tube with somewhat valvular openings at the ends, which are 

 closed before pupation. September. 



13. R. cristatella Chambers. Rather heavily powdered with black and white, 

 more evenly than usual, leaving a broad, oblique, clear white, antemedial fascia 

 from costa to fold, where it fills the spa.ce between the first two tufts; a blackish 

 shade before it; three black tufts in fold; postmedial line pale, distinct, angulate. 

 7 mm. 



Kentucky. Type only known. 



14. R. nigra Busck. Black with a silvery glance; darker than obscureUa; head 

 dark, antennae obscurely annulate. Fore wing with traces of the silvery- white 

 ground color, and a V-shaped fascia at three-fourths way to apex, its two limbs 

 paralleled by a fine line beyond. Tufts black. Hind wings blackish. Legs with 

 white annulations and tufts. 11 mm. 



May. Larva on Hypericum. 



15. R. alnifructella Busck. Purple-black; the first two fasciae from costa absent, 

 or represented by a few white scales; inner margin below fold nearly white, con- 

 trasting; the outer margin as far as the apex also strongly mottled with white. 

 Fold defined with black; the iisual tufts black and white, the outer one showing 

 as a distinct pale spot. Postmedial line whitish, irregular and broken, the upper 

 half in part parallel to costa and outlining a pale patch, the lower half often lost. 

 Head and thorax contrasting, nearly white. 10 mm. 



Caterpillar in catkins of alder in late fall, emerging in the spring. Pale; head 

 brownish yellow; cervical shield and anal plate dark brown; each segment with 

 a transverse pink band on dorsum and mottling below; abdomen with pink incisures. 



25. EUCORDTLEA Dietz 



Palpi with a dense expansible tuft on upper side of second segment; third shorter. 

 Fore wings slightly concave at Cu 2 , sinuate, apex rather obtuse, with all veins 

 preserved. Mj stalked beyond origin of R^ M 2 , M 3 , and Cu t approximate, Cu 4 dis- 

 tant, running to concavity ol inner margin. Hind wings about as wide as fore 

 wings, trapezoidal, with all veins preserved. R and M t connate, M 2 and M 3 approxi- 

 mate, M 3 and CUj nearly connate. A slight modification of Recurvaria. 



1. E. atrupictella Dietz. Pale creamy yellow, palpi with dark base and two 

 bands each on second and third segments (as often in Recurvaria). Antennae 

 annulate. Fore wing blackish-marked, an oblique band one-fourth way out, shaded 

 inwardly; a heavy oblique band from middle of costa about to fold; and a thinner 

 erect one beyond, connected to it by a bar on disc. A series of small black dots 

 around apex. Hind wings cinereous. 12 mm.

26. EPITHECTIS Meyrick 

 (Taygete Chambers; Parasia, in part)

 parallel to it; M 3 , Cu 1; and Cu., evenly spaced at origin. Hind wing with R and M t 

 stalked, R running to costa before apex, M t usually to outer margin, rarely also 

 running to costa; M 3 and CUj connate or short -stalked.
