what resembles, in form and color, the Thetis of Linnseus and 

 Drury. 



5. G. (C.) Latreillana. = Ctenucha Latreillana. Kirby. 

 Fore-wings dusky drab, with a silky lustre, and the anterior 



edge clay-colored ; hind-wings rusty black ; fringes of all the 

 wings white, interrupted with black in the middle ; top of the 

 head, orbits behind, base of the palpi, front of the breast, and a 

 spot on the fore-part of each shoulder-cover orange-colored ; tho- 

 rax, abdomen, and coxas, glaucous or greenish blue with a silky 

 lustre ; belly and legs light brown. Expands almost two inches. 

 Inhabits New-Hampshire and Maine, and, according to Mr. Kirby, 

 Canada and Nova-Scotia. 



I am indebted to the Rev. L. W. Leonard for one specimen, 

 taken by him in New-Hampshire, and to Dr. J. W. Randall for 

 another from Maine. Although they are rather smaller than Mr. 

 Kirby's Latreillana, and do not exactly agree with the descrip- 

 tion in the Fauna Bor. Amer. Vol. IV, p. 305, I think that they 

 must be referred to his species. This insect has precisely the 

 same antennae and nearly the same form as the Glaucopis of 

 Drury and Fabricius, stated by the latter author to be a native of 

 Carolina, and is, without doubt, generically allied to it, and prob- 

 ably also to several other American species, such as the Pylotis 

 and collaris of Drury. The following species, from the figures 

 given of them, seem also to belong to the same generical group ; 

 viz, Glauca, Celadon, Circe, Cmlestina, Asterea, Cephise, Alec- 

 ton, Cassand?^a, and Porphyria of Cramer. 



Subgenus PsycJiomorpha. H. (Catalogue) = Callimorpha. Westwood. 



Antennae in the males pectinated on both sides, the pectinations rather short, 

 setaceous in the female, according to Drury. Tongue moderate, spirally rolled. 

 Palpi slender, nearly horizontal, extending a little beyond the clypeus, covered 

 with loose hairs so as to conceal the joints. Wings short, somewhat triangular, 

 with the outer margins rounded ; discoidal cell of the hind pair short, closed by a 

 sinuous nervure. Body slender, hairy at tip. I-egs short, hairy ; spurs of the hind 

 tibise three, slender, nearly concealed by the hairs. 



6. G. {P.) Epimenis. Drury. = Psychomorpha maculata. 

 H. (Catalogue.) 



Brownish black ; fore-wings sprinkled in spots with light blue 

 scales, which form a narrow band near the hinder margin, and 

 marked with a large yellowish white patch beyond the middle ,• 

 hind-wings with a broad dark orange-red band behind the mid- 

 dle. The white spot of the fore-wings is indented towards the
