Fagina is ii most interesting species, for it seems to combine in 

 itself the clnmicters of several genera. The fine hair-like black 

 marking over hlui.sh-gray ground are very similar to the lucAfufja 

 section of CuculUa, but the struct ui-:i I characters are not of this 

 genus, and seem to be on the line between Calocampa and Lilltophane. 

 The subobsolescencc of the tufts, the almost rounded front and the 

 short pali)i connect it with Calocampa,\i\\\\Q the shape of the wings, 

 the presence of the thoracic crest, and the fact that the frontal tufts 

 are present, though improminent, Avould show that its affinities are 

 with the section Grai)toUtha of JAtliopliane, where I have placed it. 

 Fagina is so different from the known species that the student will 

 find no difficulty in naming it ; it seems to be, however, of very 

 rare occurrence. 



Lithophanc disposita (nov. sp.). 



Expanse, 37 m. m. Length of hody, 14 m. m. 



Antennae setiform. Palpi light gray, whitish on the inside, with a clear 

 black line on the outside extending from the first to the third joint. Front 

 and vertex with the two pair of sharply projecting tufts peculiar to LithopTiane. 

 Beneath the upper tuft a black line extending across the front. Collar with a 

 transverse ■{ -shaped black line. The usual longitudinally furrowed crest be- 

 hind the collar, in this species tipped with ferruginous. Thorax light gray 

 concolorous with the anterior wings. Abdomen with a single, slight, black 

 tipped tuft. Anterior wings light gray with ferruginous stains. The spots 

 very clearly outlined in black, the ordinary lines nearly obsolete. A slightly 

 curved, black, conspicuous, longitudinal line extending from the base to just 

 before the interior line ; and a more or less distinct ferruginous patch at and 

 above its termination. Interior line indistinctly geminate. Its outer line some- 

 times well marked on the costa, beneath the subcostal nervure and opposite 

 the orbicular forming a tooth and joining below the very distinct, elongated 

 claviform spot. The latter is outlined in black, concolorous; its apex rounded 

 and most strongly marked. Exterior line obsolete except directly opposite 

 to the claviform spot, Avhere it is distinct and black. Through the narrow
