208 THIETIETH REPORT ON THE STATE MUSEUM. [%] 



Expanse of wings from 1.50 to 1.56 inch. 



Habitat. New York ; Maine. 



Described from 2 $ 's and 3 ? 's, taken, at sugar, at Center, 

 N. Y., on October 1st, 8th, 9th 12th and 15th, by Mr. W. 

 W. Hill. The types are in Mr. Hill's cabinet. 



This species has more resemblance to X. Thaxteri, than 

 to any other of our known species. It lacks, however, the 

 marked contrasts presented in paler ground color, the heavier 

 black markings and the red dashed reniform of that species. 

 The black line on the submedian fold is not so long or so 

 heavy, and its posterior wings are not so dark. 



It resembles more closely the X. conformis of Europe, but 

 it has not the distinct basilar line, the claviform spot, or the 

 broad reniform of that species. Its transverse lines are also 

 more sharply angulated, and it is apparently a shorter- 

 winged species: 



Xylina unimoda n. sp. 



Head and thorax cinereous. Abdomen above brownish, 

 darker than the posterior wings. 



Primaries glossy, bluish-cinereous, slightly paler at the 

 costo-basal space, and with a few white scales on costal and 

 basal regions. Transverse lines inconspicuous, scarcely visible 

 without a magnifier, pale gray, faintly bordered by a darker 

 shade. Median band faintly visible, angulated on the lower 

 portion of the reniform. Anterior transverse band prominently 

 toothed ; the cellular teeth separated from the orbicular ; the 

 two small teeth inclosing the submedian fold, with some 

 whitish scales interiorly, and outwardly continued in an acute 

 claviform mark. Posterior transverse line dentate, removed 

 from the reniform. The obsolete subterminal line preceded by 

 intranervular fuscous sagittate spots. Orbicular spot pale 

 gray, darker scaled interiorly, either connected with or 

 detached from the suborbicular, which is gray-bordered 

 above. Reniform inconspicuous, cinereous, with a black 

 border more heavily marked below, and edged within by 

 gray. 



Secondaries pallid, slightly darker along the margin, with 

 paler fringes, which are almost white near the anal angle, a 

 distinct cellular spot, and faint median line. 



Beneath, secondaries paler than in X. laticinerea and less 

 thickly sprinkled with fuscous scales.
