color than the rest of the wing and not sharply defined, rather 

 indistinct. The outer line is but slightly sinuous. An obsolete 

 discal spot on the cross vein, hardly apparent. Secondaries resem- 

 bling primaries, crossed by a median shade line corresponding to 

 the transverse posterior line of anterior wings. The external mar- 

 gin improminently produced. Under surface resembling upper, 

 and without markings, except that the ornamentation of the upper 

 surface is reflected owing to the thinness of the wings. 



Expanse, & , 1.60 inch. Length of body, 0.50 inch. 



2 . Resembles the male, but is a little darker ; the ordinary lines 

 on the primaries are visibly more approximate ; this is caused by 

 the removal of the transverse anterior line nearer to the extremity 

 of the discal cell. The angulations of the external margin are, as 

 usual, more evident than in the opposite sex. The irrorations are 

 rather more apparent along the external margin than in the male. 

 Antennae simple.

Habitat. — Atlantic District. (Penna. !) 



Closely allied to E. bibularia, nob., but distinguishable by 

 the less prominent irrorations, the darker color, the more dif- 

 fuse and improminent transverse lines, the different position 

 of the first transverse line of the 2 primaries, and by the pecu- 

 liar pellucid appearance of the wings, which, while it has 

 prompted the specific name, has reminded us of the Bombycid 

 Anisota pellucida. 



EUopia cndropiaria, n. s. 



(Plate 15 A, fig. 10, £ .) 



2 . Head, thorax, and abdomen, pale whitish ochreous. Above, 

 the thorax a little darker than elsewhere. Antennae, simple, and, 

 with the legs, nearly concolorous with the body. 



Wings, whitish ochreous, evenly sprinkled with pale ochreous 

 irrorations. Anterior wings, produced at the apices and promi-
