CENOPIS. 19 



Cenopis niveana. (Plate LXIV. fig. 7.) 



Palpi about twice the length of the head, reddish brown beneath, pale greenish yellow 

 above; the second joint depressed, exposed: head and thorax pale greenish yellow. Fore 

 wings bright shining white, suffused with reddish brown, shot with bright purple over two 

 thirds of their surface, leaving only a conspicuous costal spot, a short basal patch, with a 

 projecting angle at the upper edge of the cell, and a wide band over the cilia and apical 

 margin ; the suffused portion of the wing has a mottled appearance on the dorsal half as of 

 the white ground-colour partly appearing through the shading ; two small reddish-brown 

 spots on the costa near the base of the wing. Hind wings suffused with very pale ochreous 

 brown over all their surface, except the shining Avhite margins and cilia ; underside white, 

 the red markings showing through the wing over the whole middle surface. Expanse of 

 wings 23 millims. 



Canada. 



I have not had an opportunity of comparing this species with Tortrix alisellana, Rob. 

 (Trans. Ent. Soc. Phil. ii. p. 265, pi. i. fig. 15), to which it is nearly allied. That species, 

 however, has not been described as being variable; and the Canadian form figured in this 

 volume differs decidedly from Robinson's figure in the extent and arrangement of the white 

 spaces on the fore wings ; but it is possible that it may prove to be only a variety of Robinson^'s 

 species, which is from Ohio. 



Cenopis pulcherrimana. (Plate LXIV. fig. 8.) Q^aJuMa^^ 



Palpi scarcely twice as long as the head; both pale yellow straw-colour; antennae tinged 

 with chestnut-brown. Fore wings — with the costa abruptly arched at the base, nearly straight 

 beyond, slightly rounded at the apex; the apical margin convex; the dorsal margin bulged at 

 the base, straight beyond — pale yellow straw-colour, suffused over a great part of their surface 

 with pale chestnut-brown, such parts having a slightly mottled appearance. The pure ground- 

 colour of the wing appears only in a large triangular costal spot extending from near the base 

 to beyond the middle, in a smaller spot near the base of the dorsal margin, and on the apical 

 margin, where it forms an ovate blotch. Hind wings shining white. 1 ?. Expanse of 

 wings 17 millims.

Cenopis demissana. (Plate LXIV. fig. 9.) ^JicJU£i''<K 



Palpi, head, and antennae ochreous, more or less shaded with fuscous. Fore wings twice 



as long as wide — with the costa abruptly arched near the base ; the apical margin oblique, not 



indented; the dorsal margin rounded — ochreous straw-colour, with a faintly reticulated 



appearance, having an indistinct ochreous spot at the end of the cell. Hind wings very pale 



straw-colour, tinged along the apical margin with ochreous. 1 $ ,% ? . Expanse of wings 



7-8 1 lines.
