NOCTUID.E. — LEUCANIA. 73 



advertently given the preceding as a desideratum to my cabinet, 

 instead of the present species. 



t Sp. 4. Cannae. Alis anticis Jlavo-rufescentihus serie unicd maculdque obsolehl 



in medio nigris. (Exp. alar. 1 unc. 8 lin.) 

 No. Cannae. Ochsenheimer. — Steph. Catal. part ii, p. 101. JVo. 6332. 



Head and thorax pale reddish, or yellowish-ash ; anterior wings the same, with 

 a few minute dusky atoms, with some larger spots at the base, and a row stiU 

 more distinct towards the hinder margin, and forming an arcuated striga : in 

 the middle of the disc is a single spot of similar hue : posterior wings reddish 

 or yellowish-ash. 



There is a single example of this species (which is much smaller 

 than either of the foregoing) in the collection of Mr. Stone, cap- 

 tured near Scarborough : and I believe there is a second in that of 

 Mr. Haworth, taken by him near Hull. 



Genus CXXXVII. — Leucania, Ochsenheimer. 



Palpi rather short, considerably bent upwards, approximating, the basal joints with 

 elongate compact scales, the terminal exposed and nearly denuded, obtuse; basal 

 joint slightly bent, horizontal, second vertical, as long again as the first, slightly 

 bent at the base, and a little attenuated at the apex ; terminal slender, elongate- 

 ovate : maxillw moderate. Antennas simple in both sexes, thickly cihated be- 

 neath, especially in the males : head small, subtrigonate : eyes globose, large, 

 pubescent, rarely naked : thorax rather stout, wooUy, not crested : abdomen 

 slightly elongate, carinated, rather slender in the males, with a large tuft at 

 the apex, stouter, and somewhat conic in the females : wings incumbent during 

 repose; anterior r&ther narrow, the hinder margin entire, the apex acute; 

 nervures distinct, apparently elevated. Larva slightly pilose: pupa fol- 

 liculated. 



Exclusively of other characters, Leucania may be known from 

 Nonagria, by the integrity of the hinder margin of the anterior 

 wings; the insects are generally of much smaller size; and their larva 

 are not internal feeders, but they are pilose, and subsist upon 

 leaves ; the pupa being folliculated.

Head and thorax pale fuscous-ash, with a rufescent tinge, the latter with a 

 transverse darker streak in front, and a few scattered black atoms : anterior 

 wings cinereous or pale fuscous, the costa whitish at its base nearly to the apex;
