Female. — The wings are nearly as minute as in Anisopteryx ; the legs are 

 larger than in either of the other two genera, and the head is a little fuller 

 in front. 



Larva. — "Caterpillars more or less elongated, cylindrical, a little carin- 

 ated laterally, with a spherical head; living exposed on trees and bushes. 

 ( ihrysalids subterranean." — Guenee. 



This genus differs from the American species of the two previously 

 mentioned in the much rounded lore wings, the smaller, fuller front of the 

 head, the long hind wings, and the ochreous color of the single species known. 



Hybernia tiliaria Harris. 



Hybernia iiliaria Harris, Inj. Ins. Mass., 341, 1841 ; 3d ed. 472, i\g. 236, £ , 1862. 



6 £ . — Pale ochreous, with light-brown specks and bands. Head, body, 



costa, and transverse band on the wings concolorous, being pale brown. Fore 



wings with a faint, curved, sinuate, diffuse inner line ; outer line dark brown, 



slightly sinuate, with a large obtuse angle on the independent vein. It is 



shaded externally with a broad pale-brown band, which breaks up into flecks 



on the outer edge; on the costa, the outer edge is directed obliquely toward 



the apex. Outer edge of wing as within the band. A well-marked discal 



dot. Hind wings without any markings, somewhat paler than the anterior 



pair. Beneath, of the same color as above, the outer dark line appearing; 



discal dots very faint on the fore wings and distinct on the hind wings, where 



they do not appear above. 



Length of body, 0.60 ; fore wing, 0.90-0.95 ; expanse of wings, 2.00 



inches.

Mass. (Sanborn); Albany, X. Y. (Lintner and Meske) ; Philadelphia, Pa. 



(Ent. Soc). 



It differs from H. progemmaria of Europe, to which it is closely allied, 



by wanting the marginal row of black dots and the line on the hind wings, 



while the outer line on the fore wings is more angulated than in the European 



species ; and in wanting the discal dot on the hind wings, though in additional 



specimens this may occur. Occasionally a specimen is much suffused, the 



lines, forming a broad shade. 



Female (four examples). — The female of this species differs from any 



other of our wingless species by its much larger size, the white ground-color
