Lithophane cinerosa u. s. 



3 2 . Antennae white at base ; facial liairs mixed "^itli wMte. Eobust 

 and liairy; color dark blackisli gray, relieved by tlie white shading of 

 the orbicular, which is either double or extends below the median vein ; 

 figure of 8-shaped. Lines denticulate, more or less distinctly filled in 

 with whitish gray. Hind wings blackish fuscous, with concolorous, 

 white-tipped fringes. Beneath pale gray, with disc of primaries fuscous, 

 finely irrorate, with an irregular extramesial line, and half-open discal 

 spot on secondaries. Uxpanse, 42-44 mil. 



Ilab. — New York State, in September. 



This form is more strikingly blackish and grayish white than the rest, 

 with a darker background of primaries. The ground-color of cinerea 

 and laticinerea is the same ; the latter is larger, without ferruginous 

 tintings 5 unimoda has obliterate markings and a darker, slightly purx5lish 

 or bluish tint ; cinerosa is the most distinctly marked and striking of 

 these forms, which may all, in reality, be found to be still genetically 

 connected. Of cinerosa, I have examined a very large series in the col- 

 lections of Messrs. Lintner, Hill, and Dr. Bailey. 



Lithophane hemina u. s. 



$. Allied to disposita, petulca, signosa, etc. Darker than disposita, 

 longer-winged, and allied to that species in having a black basal dash, 

 but more obscurely colored — dirty wood-brown — resembling Hadena vul- 

 garis in this respect, but less warmly tinted. A black stain on submedian 

 fold, where the median lines approximate, as in signosa. Terminally, 

 the wing is twice stained with blackish. Spots and lines less distinctly 

 limited than in disposita, and more as in petulca; orbicular irregular, 

 oblique; reniform wide above. Hind wings fuscous, with fine black ter- 

 minal line and i3aler fringes. Beneath, the wings are paler, with dis- 

 tinct black discal spots, subkrorate; the under surface is much like dis- 

 posita; there is a faint irregular line on secondaries, and the discal field 

 of primaries is shaded with fuscous. Thorax a little darker than fore 

 wings; abdomen dusky, with reduced tufts on the dorsum. Ilxpanse,4:0 

 mil. 



I have seen specimens in Mr. Hill's collection, collected in Lewis 

 County, ]^ew York, in September. I am indebted to Mr. Hill's kindness 

 for the type. The species seems to me to stand between disposita and 

 petulca. There is a curious general resemblance in ornamentation and 

 color between this species and the wider-winged Hadena vulgaris, while 

 they are structurally easily distinguished. 



Perigrapha praeses n. s. 



^ . This form has haiiy eyes, a broad, flat, straight-haired thorax with 

 a tuft behind the collar, a flattened abdomen (like Glcea), a discolorous, 

 slightly excavate collar (somewhat like Metalepsis cormita), and unarmed 

 tibite. Head and pectus puri)lish black, reddish on the hairy front. 

 The tuft behind the collar prevents a reference to GrapMpliora, and
