This is 0. tracta Grote. Not having seen Hiibner's figure, I am not perfectly- 

 clear as to the species he intends, but this agrees very well with Guenee's de- 

 scription, Noct. 1,221. The species has deep brown fore wings, sometimes 

 pale along costal region, the t. p. line followed by a white shade, the reniform 

 moderate. v, 



Oligia arua Guenee. March 25 to April 29. No. 103. 



This agrees with Guen6e's description, except that the large reniform can 

 hardly be called "oblique." The color is olive gray, tinted more or less obvi- 

 ously with ruddy, and having the reniform usually, but not invariably, picked 

 out by dark brown shades inferiorly. The species occurs likewise in the mid 

 die states, and is provisionally determined (with an ?) as chalcedonia in the col- 

 lection of the BuflFalo Society of Natural Sciences. 



Hadena patina n. s. 



5 . — Belongs to the section xylophasia. A species of moderate size, with a 

 pale, creamy brown, ground tint to the primaries which prevails but slightly, 

 most prominently on subterminal space, the wing being largely shaded and 

 marked with black. No basal dash. A distinct black dash on internal margin, 

 preceding the long final acute tooth of the t. a. line. T. a. line geminate, improm. 

 inent, and not acutely toothed superiorly, nearly even or a little waved to the 

 prominent acute inflection on internal margin. Claviform small and rounded. 

 Orbicular not very evident, rounded, rather large, pale ringed. Reniform 

 squarish, incompletely annulate, the ring marked laterally by black and white 

 points, the white points larger outwardly. Above the reniform, two more 

 prominent black marks, the inner indicating the median shade which appears 

 near the t. p. line below the median vein, as a rivulous line. T. p. line gemi- 

 nate, even, followed by a large black blotch before the subterminal line and 

 interrupting the pale subterminal ground color between veins 1 and 2. Black 

 points follow the t. p. line. Subterminal line vague, followed by minute white 

 points surrounded with black. The pale brown color forms the usual W mark , 

 interrupting the black terminal space. Hind wings shaded with fuscous out. 

 wardly, pale at base ; fringes pale. Beneath pale, irrorate, both wings darker 

 outwardly, with a common rivulous exterior line bending inwardly before 

 anal angle of hind wings which show a small discal dot. Collar with a vel- 

 vety black line ; thorax dead black, tegulae brownish. Expanse, 33 m. m. No. 

 485. March 23.
