LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 137 



11. CHOROPLECA Walsingham and Durrani 



(Cyane Chambers, not Felder) 



Similar to Tinea (fig. 89, antenna). Fore wing ample (fig. 86), with Cu arising 

 out on the cell not unlike Incurvaria; all veins separate. Hind wing trapezoidal, 

 broad; one vein wanting, all veins separate. 



1. C. vesaliella Chambers. Whitish, dusted, striate and mottled with blackish. 

 Head dirty white, mixed with brown behind. Antennae annulate, with groups of 

 darker segments near base, half, three-fourths, and seven-eighths way out. Fore 

 wing with costal area and base dark brown; black in patches, the dark area extend- 

 ing halfway across the wing at its middle as a large spot, and cut by several 

 white bars. Inner margin with a couple of brown spots, and smaller ones on the 

 disc. Apical fringe with white bars, dorsal fringe pale. 8.5-11 mm. 



This species looks rather like a Tinea. It flies in June. 



Parry Sound, Ontario; south to Florida and Louisiana. "New York" (Dietz). 



12. HYBROMA Clemens 

 (With Isocorypha Dietz, in part) 



Antennae rather more than half as long as fore wing; fore wing normal, typically 

 with all veins free (fig. 85) in E. (?) chrysocomella (fig. 83) with R 4 and R B 

 stalked and Cu, lost. (H. servulella shows a^ trace of the basal fork of A.) Hind 

 wing with costa arched, Sc extending well beyond middle, R straight, running to 

 costa, M primitive, forking well before middle of wing, M 1+2 connected by a trans- 

 verse vein to R but M 3 free; M running to apex. Cu forked, free. 



In placing chrysocomella in this genus rather than in Isocorypha, I have put 

 more weight on the unique venation of the hind wing than on the fore wing, which 

 agrees with that of mediostriatella. 



1. H. sen'ulella Clemens. Bright light yellow; antennae fuscous. Fore wing 

 with costal edge brown from base, widening into a patch beyond middle, which 

 may rarely extend across the wing; a second patch two-thirds way out; basal half 

 of inner margin with an irregular brown patch. Yellow ground when least 

 extended, appearing as four, partly confluent, rounded spots, besides the yellow 

 apex. 11 mm. 



June and July. 



Cohasset, Massachusetts, to western Pennsylvania, northern New Jersey, and 

 Missouri. 'New York: Ithaca. 



2. H. (?) chrysocomella Dietz. Closely similar to H. servulella, but with brown 

 markings more extensive, usually cutting off a rounded yellow spot at the anal 

 angle. Ground rather darker, the markings more purplish. 7 mm. 



Kansas and westward. 



13. LEUCOMELE Dietz 



Similar to typical Hybroma; wings (fig. 81) much narrower, hind wing with 

 sinuate costa, Sc extending less than half the length of the wing, with all three 

 branches of M connected to R by a short cross-vein, and base of M lost. Ovipositor 

 extensile, membranous. 



1. L. miriamella Dietz. White; vertex and thorax dark purplish brown; fore 

 wing dusted with blackish, gathering to form streaks along costa and base of inner 

 margin; a couple of bars in fold, and several lesser spots. Apex darker. Fringe 

 checkered at base, outer part whitish with a dark dividing line. 9.5-14 mm. 



The types were taken on the trunk of a cherry tree in June. The apical third 

 of the fore wing may be suffused with black except for the barred fringes; and the 

 bars in the cell may fuse into a heavy oblique fascia.
