dots on the nervules representing tlie subterminal line, and from this point 

 outwards the nervules are narrow, marked in black. Posterior wings whitish- 

 gray, with faint discal dot and exterior line, no terminal dark band. Fringe 

 white. Beneath, the wings are whitish-gray, the anteriors rather the darker, 

 with a yellow spot at the base. Posterior with discal dot and exterior line. 



Hah., Cambridge, Mass., April 15, 1874. From my collection. 



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

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

 marking over bluish-gray ground are very similar to the lucifuga 

 section of OuculUa, but the structural characters are not of this 

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

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

 short palpi connect it with Calocampa, while the shape of the wings, 

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

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

 with the section Graptolitha of LWiophane, 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. 



Lithopliane disposita (nov. sp.). 

 Expanse, 37 m. m. Length of body, 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 LitJiophane. 

 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, where it is distinct and black. Through the narrow
