here continued. Beneath, with the lines repeated, on secondaries a discal dot. 
Aé primary wing measures 12 m. m, along costa. 
Habitat, Philadelphia; Buffalo, Olean, Albany, N. Y. (8629, 
coll. Lintner). 
The imago flies in June and July in company with Philometra 
on low grounds in herbage. Fresh specimens are deeper colored, as 
the active moth readily loses its scales by attrition. 
Litognatha litophora, Grote. 
é 9.—Of the usual pale gray color, but powdered with brown scales, not 
olivaceous, as in Pityolita or ochraceous as is more usual in Zanclognatha, 
The transverse posterior line has the same shape as in Pityolita, but it is 
dark brown, and is continued with nearly the same distinctness across the 
secondaries which are concolorous. Subterminal shade faint on both wings. 
Terminal line very distinct, dark brown, fine and subcontinuous. Fringes 
soiled with brownish. Beneath, the wings are darker than above. The t. p. 
line is reproduced with great distinctness acrcss both wings. <A primary 
wing measures 12 m. m. along the costal edge. 
Habitat, Philadelphia; Albany (2, 2535, Lintner legit). 
Meghypena, n. g. 
Ocelli. Labial palpi very long, as long as the thorax; third joint small, 
porrected, second very long, a little excavate beneath, projected straightly 
forwards. Primaries wide, swelled at the shoulder, depressed medially, rising 
to the acute apices below which the external margin recedes, rising again 
opposite the median nervules ; internal margin straight. 
This genus differs from Macrhypena in the much longer palpi 
and acute apices of the primaries. The wings are unusually ample 
yet proportionate, hence differing from Plathypena with its wide 
secondaries and narrow primaries. The propinquity of the median 
lines is noticeable. The species are recognisable from the irrorate 
character of the ornamentation. Beneath, on the secondaries, this 
is quite noticeable, the discontinued darker streaklets reminding us 
of some Geometridae quite strongly. My material is limited to 
single specimens of either species.
