444 William T. M. Forbes 



Caterpillar on chestnut, rolling the tip of the leaf. Moth in early spring, locally 

 very common. 



Xortheastern States : exact distribution uncertain. 



4. E. haracana Kearfott. R, and R not stalked. Head and thorax blackish. 

 Fore wing blackish with obscure coarse violet -gray striae: becoming finer paired 

 whitish ones at costa. An irregular black line from outer part of cell to apex, 

 evanescent under high magnification. Speculum composed of two long lead-gray 

 bars, the outer one broken: filled with clay-colored powdering, which also covers 

 the region above it. below the dash. Three or four black bars in speculum. Fringe 

 with faint longitudinal lines; the dash in the apex obscure. Hind wing rather 

 pale. 15 mm. {faracana Kearfott?) 



I have seen no decent material of this species; some specimens determined as 

 faracana appear to show the longitudinal black streak in the axis of the wing. 

 Xew Jersey; Pennsylvania; Missouri? 



5. E. costomaculana Clemens. Fore wing light pinkish ochreous or cream color, 

 paler about the edge of the dark patch; a few scattered black scales. A large 

 rounded brown patch, extending down from middle of costa, sharply defined below, 

 but somewhat diffuse above and shading into the pale ground. Patch shaded 

 with black. Fringe grayer than ground, dark at apex. 16 mm. 



This species and the next differ from the similarly marked Epinotias in the 

 pale base of the fore wing. 



Common and general in distribution, April and May. 



Xew York: Gowanda, Rock City (Cattaraugus County), Portage. Crosby (Yates 

 County), Ithaca. 



6. E. virginiana Clemens. Closely similar to E. costomaculana but averaging 

 a little larger; ground light violet-gray, shaded with brown, especially below 

 apex; not paler than hind wing. Patch rather darker brown than in E. costo- 

 maculana. Speculum indicated by well-marked black dots in the brown outer 

 shade. IS mm. 



April and May. 



Pennsylvania. Xew York: Ithaca, Pearl River, Albany. 



24. GYP80N0MA Meyrick 

 (Epinotia, Hedya, in part) 



Fore wing with apex rather marked, but not distinctly falcate, usually marked 

 by an ocellate apical spot; outer margin concave, but more broadly than in the 

 preceding genera: in H. haimbachiana. suggesting Anchylopera : M, to M 3 slightly 

 approximate at margin ; R arising from cell at middle ; R halfway between Rj 

 and R; accessory cell short, commencing before the point of separation . of R; 

 Cu, straight; no costal fold. Hind wing with R and M, stalked. (Fig. 274). 



Valve club-shaped: cucullus moderate: clasper rudimentary; anal indentation 

 smooth; sacculus sparsely hairy. Uncus wanting: socii as in Charlotta, articu- 

 lated on a stem, the gnathos partly fused with them. 



1. G. fasciolana Clemens. White, shaded with gray toward outer margin; a 

 few black scales in position of speculum. Outer part of costa dark gray, crossed 

 by paired white striae. Base blackish, the outer boundary oblique outward and 

 a little convex; a broad fascia of the same color from middle of costa to before 

 anal angle. 15 mm. This is very similar in markings to some species of Exartema 

 and Olethreutes, but may be distinguished by the stalked M 3 and Cu a of the 

 hind wing as well as by the lack of the fold on the inner margin in the male. 

 There is a good deal of variation in the details of- markings and the species 

 should probably be divided. This species and the next represent Meyrick's genus 

 Gypsonoma, but there do not seem to be any really tangible characters. (Epinotia 

 auct., Anchylopera Clemens; blakeana Grote. ) 



July.
