dark, slightly oblique sinuate lines ; the outer side of the band is very 

 irregular, consisting of two large, unequal, subacute teeth, the lower 

 larger and double ; below, the band contracts, being bidentate on the 

 outer edge, which is black. Beyond is a row of nervular dots ; the 

 usual submarginal whitish zigzag line, with the edge black between 

 the nervules ; fringe dusky. Hind wings with indistinct dusky zigzag 

 lines. 



Beneath, the outer side of the mesial line is partially reproduced, 

 especially on the costa. Discal dot distinct, especially on the hind 

 wings, which are crossed by two outer black irregular lines. 



Length of the body .40 ; fore wing .55 inch. 



This species is a transitional form to Cidaria ; its essential charac- 

 ters closely allying it to Cidaria, while the style of coloration is that 

 of Coremia, though we should scarcely feel justified in uniting the 

 two genera. 



It differs greatly from C.propugnata, in the dull brown middle por- 

 tion of the middle band ; and in its very irregular and quite different 

 outer edge, with its mottled and strigated outer border. Like that 

 species, however, it wants the geminate dark spots on the outer mar- 

 gin of the fore wings. 



Caribou Island, Labrador. 



Cidaria russata W. Verz. 



Specimens not differing from those inhabiting New England, espe- 

 cially Maine and the White Mountains, occurred not unfrequently at 

 Caribou Island, August 19. 



Cidaria brunneata n. sp. 



This fine species in its long, slender, acute wings, with the outer 

 margin unusually oblique, and in its style of marking, is related to C. 

 russata, though very much smaller. It may be readily recognized by 

 the two broad brown bands, which are irregular on the edges. 



$ . Antennae filiform, long and slender, minutely ciliated beneath, 

 basal joint white. Palpi short and small, rather hairy, a little up- 

 curved, scarcely passing beyond the front, which is cinereous, with 

 dark scales. 



Thorax cinereous, with dark scales, abdomen paler cinereous. 

 Wings quite uniformly dark ashen ; a sub-basal irregular brown band, 

 whitish on the costa, and edged with whitish below ; a broad, mesial, 

 dark cinereous band, three times as broad on the costa as on the inner 

 edge, with each side irregular dentate ; on the inner side a large tooth 

 near the inner edge of the wing ; on the outer edge, a large tooth sit- 

 uated on the first median nervure. Beyond, is a broad brown band,
