LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 325 



mistaken for 1st A, which is absent. Hind wing normal; Cu x and Cu 2 somewhat 

 approximate. The European species (Sorhagenia Spuler) has apparently lost Cu 2 

 completely, and is a twig-miner and later a leaf-roller on Rhamnus. 



1. W. amorphella Clemens. Head, thorax, and basal third of wing smoky black- 

 ish, somewhat mottled. Antennae and palpi nearly concolorous. Fore wing with 

 outer boundary of the dark area oblique outward, with a moderate blackish tuft in 

 the cell and a very large one on the fold, just before it (unlike Laverna). Outer 

 ] art of wing paler, mottled clay -color and light brown, with some black scaling, 

 tending to leave a somewhat paler, outwardly oblique median fascia, and a vague 

 broken angulate subterminal one. Median fascia with a large transverse tuft across 

 the cell, and a small one below the fold; a black dash in the fold just beyond them. 

 A small tuft at end of cell. Terminal dots black. Many^of the scales white-tipped, 

 most strikingly at the margin. 15 mm. (miscecolorella Chambers.) 



Mav; July. The caterpillar forms a gall on Amorpha fruticosa, pupating in the 

 gall. (H. p. 430, f. 249.) 



New Jersey to Minnesota and Missouri. New York: Ithaca. 



4. STILBOSIS Clemens 



Xo pecten, scape rather long and slender. Palpi long, smooth, and slender; third 

 segment as long as second. Fore wing heavily tufted, in our species with strongly 

 metallic vestiture, the tufts as in Walshia but larger, and tending to fuse in pairs. 

 Fore wing narrow (fig. 188) four times as long as wide; costa slightly concave; 

 M, stalked with R 5 nearly to apex; Cu 2 obsolescent at base, but not approximate to 

 CUjj 1st A lost. Hind wing a third as wide as fore wing, linear, with concave 

 costa; R obsolescent, apparently long stalked with Mjj the remaining veins sepa- 

 rate; fringe five to six times as wide as membrane. 



1. S. tesquella Clemens. Shining dark lead-color; antemedial tufts black; median 

 and discal tufts in large straw-yellow patches, the latter connected with a straw- 

 yellow costo-apical spot. 9 mm. ( quinquecrist at ella 'Chambers. ) 



May to July; August. Caterpillar between leaflets of Amphicarpa monoica and 

 Lespedeza; light yellow, with concolorous head, black shields, tubercles and true 

 legs. July. 



New York and North Carolina to Minnesota. New York: Ithaca; Sea Cliff, 

 Long Island. 



5. LOPHOPTILUS Sireom 



(Cyphophora Herrich-Schseffer ; Leucophryne Chambers; Laverna, 



Mompha, in part) 



Palpus nearly smooth, third segment three-fifths as long as second. Similar to 

 Laverna. No pecten; 1st A of fore wing (fig. 183) stalked or free, well developed; 

 hind wing three-fifths as wide as fore wing; R running to costa a short distance 

 before apex; Mj and M 3 stalked, widely separated from M 3 ; upper and lower dis- 

 cocelhriar veins transverse. Tufts on fore wing normally heavy; fringe normally 

 even. 



L. eloisella and passerella are strongly aberrant in having minute raised tufts 

 and a strongly caudate apex, and perhaps should be separated generically. The 

 larvae, so far as known, feed on Onagrace*. 



Key to the species 



1 . Ground white, apex caudate. 



2. An antemedial fascia ; smaller 3. passerella,. 



2. Two antemedian black dots; larger 2. eloisella. 



1 . Ground gray, apex not caudate 1. tricristatella.
