NATURAL SCIENCES OF PHILADELPHIA. 548 



Hind wings much broader than the fore wings ; with the costal and subcostal 

 veins from a common stalk, the latter bifid beyond the disk, which is closed 

 by a faint vein. Median vein 3-branched. the two superior on a common 

 stalk, which becomes bifid opposite the fork of the subcostal. 



Head rather small, free, smooth ; without ocelli. Face moderate, flat, 

 smooth. Eyes moderate, prominent. Antenna? simple, setose in both sexes ? 

 Palpi moderate, recurved, but little exceeding the clypeus. squamose ; the 

 basal joint tumid, and about equal to the middle joint, which is cylindric ; the 

 terminal joint slender and nearly equal to the middle joint. Tongue slightly 

 more than one half us long as the thorax beneath. 



Body moderately thick, rather less than the length of the hind wings. Pa- 

 tagia small, nearly cylindrical. Abdomen beneath one half the length of the 

 body. Legs rather stout ; fore tibiae with a short spur at the base ; hind 

 tibiae with four moderate spurs. 



A.? miniata. Lithosia miniata, Kirby, Faun. Bor. Am. iv. 305, 1. Gnopria 

 vittata, Harris, Ins. Mas. 2d ed. 262. Scarlet or yellow tinged with scarlet. 

 Antennae black. Palpi tipped with black. Fore wings with three broad slate 

 colored or lead colored stripes, the first near the costa ; the third near inner 

 margin ; the second short in the middle of the wing posteriorly. Hind wings 

 blackish slate colored, scarlet or pinkish at the base. Abdomen black with a 

 broad scarlet stripe beneath.

Wings rather broad, semi-diaphanous, rounded. In the fore wings the sub- 

 costal vein forms a large subcostal cell over the discal vein, giving rise about 

 the middle of the cell above to a marginal nervule, and beneath to the sub- 

 costo- inferior and discal vein, the latter having a disco-central nervule. At 

 the apex of the cell behind, the vein becomes trifid, dividing into a marginal, 

 post-apical and apical nervules, the latter with a nervulet from its middle. 

 Hind wings about equal to the body in length ; without costal vein ; subcostal 

 vein with a marginal nervule arising from the disk near the discal vein, and 

 becoming bifid exteriorly at a point remote from the discal vein ; with a disco- 

 central nervule. Median 3-branched, with the posterior nervule somewhat 

 interior to the origin of the marginal nervule. 



Head free, rather small, smooth ; without ocelli. Face smooth, rather nar- 

 row, clypeus prominent. Antennas setiform, moderately long, scarcely ciliated 

 in the males. Palpi slender, slightly curved, but little exceeding the clypeus, 

 slightly hairy at the base ; the basal joint twice larger than the middle ; ter- 

 minal joint minute, ovate. Tongue as long as the thorax beneath. 



Body slender. Patagia nearly obsolete. Legs rather long and slender ; 

 fore tibiae unarmed ; hind tibiae with four spurs, the middle pair short. 



Eggs globular, pale yellow ; producing larvae one week after deposition. The 

 larva in escaping from the egg is geometriform, with ten legs. This refers to 

 the species described below which differs sufficiently in structure from the 

 European N. m u n d a n a , it appears to me to authorise the separation of our 

 species from the group containing the European species. It may belong to the 

 Geomettina. 



N. men die a, Walker, 576. Pale yellowish. Fore wings with the costa 

 at the base frequently touched with ochreous, with two irregular oblique 

 blackish, sometimes pale grey, bands, composed of large spots ; one on the 

 middle of the disk, and the other crossing the nervules, and a single spot of 

 the same hue near the hind margin in the medio-central interspace, sometimes 

 connected with the posterior band.
