AMERICAN LEPIDOPTERA. 95 



in C. obscura and C. simulatilis, which agree in the general smoki/ ashen primaries 

 and the white fringes to the hind wings, but may be separated by the course of 

 the t. p. line. This, in C simulatilis, is much as in C. residua and the other species, 

 with two very prominent teeth and wide open subreniform, whereas, in C. ob- 

 scura the line is more perpendicular and presents a series of fine teeth. The 

 resemblance is otherwise so great between the two that other comparison or 

 description seems unnecessary. Since I only know males of C. obscura and 

 females of C. simulatilis, I thought that my specimens of the latter might 

 belong, as the opposite sex, to C obscura. Such a sexual difference would be 

 quite new and unusual, and I cannot now be blamed for not adopting such a 

 determination. Expanse 65 mm. 



Ohio, Dr. Hodge, two specimens. 



Dr. Hodge has kindly communicated to me a specimen of C. reudua 

 taken in the same locality, and this species has also been taken in con- 

 siderable numbers in Chatauqua County, New York, during the present 

 summer. 



Catocala L<evettei, Grote. — %9- — Forewings pale smooth greenish 

 gray, with very fine black transverse lines; the t. a. notched on s. c. vein, 

 thrice rather deeply waved. T. p. line exserted opposite the cell, with a more 

 prominent tooth, edged outwardly with white, the narrow open subreniform 

 white filled. Subterminal line dentate, whitish filled between fuscous shades, 

 from vein six a fuscous shading crosses the terminal space obliquely to below the 

 apices. Terminal black interspaceal marks, followed by white, very distinct. 

 Thorax like forewings, with mixed black scales on the collar and tegulee. 

 Hind wings black with blackish fringes. Abdomen above with a blackish shade. 

 Beneath, the body parts are white; second joint of palpi black. The wings are 

 white at base, with narrow pale interspaces between the bands, and resemble 

 generally the other species. Expanse 45 to 50 mm. 



Indianapolis, Mr. J. W. Byrkit. 



The smallest species of black winged Catocala, except C. tristis, yet 

 discovered. Smaller than 0. fiehilis, and with paler forewings, appear- 

 ing like a minature C. Rohinsoni. 



I name this species with great pleasure after my kind friend, Dr. 

 Levette, of the State Survey of Indiana. 



Catocala innubeus, var. flavidalis. 



I have received from Prof. S. A. Forbes, Xorraal, Illinois, a specimen 

 with the number " 2" attached to it, which resembles C. innubens in 

 evert/ respect, except that the hind wings are dark yellow instead of 

 orange. The condition of the specimen does not allow of the sugges- 

 tion, that this change of color is owing to etiolation.
