AMERICAN TORTRICIDAE. 27o 



Under surface of both pairs pale straw color, the anterior pair slightly 

 reflecting the hue and markings of the upper surface. 



Krpause, % 17—19 mil.; 9 20—22 mil. 



naOifaf.—Vntnum Co. N. Y., West Va. (Ridings), Pa. 



This species varies greatly, the reticulations being sometimes obso- 

 lete and the ordinary markings partially so. I consider the specimens 

 tigured and nuujbered 35 and 36 to be varieties of this spei'ies.

 Conchi/Iis grata)ia, Walker, Brit. Mus. List, part 28, p. 359, 1863. 



Palpi long, exceeding the head, yellow above, deep red laterally and 

 beneath. Head and thorax yellow above tinged with red or purple at 

 the sides. Patagia red in front, yellow beyond. 



Anterior wings golden-yellow finely reticulated with red or purplish. 

 Sometimes the reticulations are wanting (fig. 40). Costa tinged with 

 purple at base. A purple spot on the middle of internal margin throws 

 out two diverging lines, one of which attains the costa at basal third 

 the other ending just below a similarly colored subapical costal spot. 

 A broad purple stripe along external margin. Fringes yellow. 



Posterior wings above and beneath varying from pale yellowish fus- 

 cous to dark fuscous or blackish. 



Under surface of anterior wings clouded centrally with fuscous; the 

 margins paler, sometimes yellow. 



Expanse, % 14 — 17 mil. 9 17 — 19 mil. 



Habitat. — Mass., N. Y., Pa., West Va., Ohio, Illinois, Florida, Texas. 



Dr. Clemens, (Proc. Ent. Soc, p. 518, 1867,) after describing some of 

 the forms which I have united above, says : " I have described these 

 various forms as distinct for the reason that the eye detects differences 

 in them, without however believing that they are all specifically distinct." 



An examination of Dr. Clemens' original types and of nearly one 

 hundred specimens from the localities cited above, would seem to prove 

 that this is a very variable species and that the intermediate forms are 

 so graduated that it is not possible to limit the varieties. 



Tortrix albicomana. (Plate v, figs. 41 — 42.) 



Xanthosctia albicomana, Clemens, Proc. Ent. Soc. Phil., v, p. 137, 1865. 



Palpi, head and thorax pale yellow. 



Anterior wings bright lemon-yellow, all the central portions clouded 

 vith purple, the ground color being only exposed at base below costa,
