LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 235 



costal edge somewhat dusted with fuscous; two obliquely placed dark dots at 

 one -third, and a series of three at end of cell, the discal largest; sometimes the 

 three fused into an oblique band. A strongly bent subterminal band parallel to tip 

 of costa and outer margin. Apex infuscated. Markings tending to disappear in 

 rubbed specimens. Hind wing whitish, abdomen and fringes straw. 13 mm. 



The moth occurs in July and August. 



Southern Massachusetts to Ohio, Maryland, and Texas. New York: Ithaca. 



4. CRYPTOLECHIA Zeller 

 (In part; Machimia Clemens) 



Similar to Gerdana; palpi much longer, second joint reaching vertex; wings 

 in our species more ample. This genus also occurs in Africa and Australia (figs. 

 138, 147). 



1. C. tentoriferella Clemens. Light ochreous; when fresh, more or less shaded 

 with reddish and dusted with black; two contrasting discal dots, and a blackish 

 spot in fold halfway between them; a broken punctiform postmedial line parallel 

 to outer margin and a series of black terminal dots. Head pale, palpi nearly white, 

 with basal half contrasting blackish. Hind wing lightly infuscated. 22 mm. 

 (fernaldella Chambers). 



General in distribution ; common in late August to October on trunks of trees. 

 Caterpillar in August on oak, cherry, maple ( ? ) , chestnut, etc., in a flat tent on 

 under side of leaf at one side of midrib, bending the leaf; feeding outside the tent. 

 Caterpillar dark green. Cocoon under a folded edge of the leaf; of dense silk except 

 at the point where the moth emerges. 



New York: Potsdam, Ithaca, Big Indian Valley, Schenectady, Karner, Rhinebeck, 

 New Windsor, New York City; Moravian Cemetery, Staten Island. 



5. PSILOCORSIS Clemens 

 (Cryptolechia, in part) 



No pecten. Palpus very long and slender; third joint nearly as long as second 

 (fig. 148). Fore wing with squarish apex and more vertical outer margin than 

 in Cryptolechia; R 5 rarely running to the apex, as in some Depressarias, from 

 which the, genus is distinguished by the lack of pecten, and by its smoother palpi. 

 Ground color luteous to light brown. Second joint of palpus with a black ventral 

 line edged on both sides with white; third joint white with three black lines, the 

 middle one continuous with the line on the second joint. Scape of antennae with 

 two black lines with a white one between them; shaft on upper surface normally 

 with two longitudinal black lines toward base, with white between them, becoming 

 transversely barred with brown outwardly; the under side evenly pale. Fore 

 wing transversely strigose with darker brown or black, usually with a black 

 terminal line and sometimes with a dark fringe, but without other sharply defined 

 markings. 



All the species are very similar and are practically impossible to determine 

 without a knowledge of the larva. 



The larva lives in a slight web between two leaves of the food plant, skeleton- 

 izing the leaves, which turn brown. It has rather distinct tubercles; on the eighth 

 segment of the abdomen, iii is directly in front of the spiracle, and iv and v, below 

 it. . Pupation takes place in the web. 



1. P. quercicella Clemens. Luteous, strigoso with brown. Terminal line black, 

 broken, contrasting, variable in length; fringe lead gray. A dark shade across
