AMERICAN LEPIDOPTERA. 107 



with the fore wings cleft in the male. And with four specimens of T. 

 bifidalis before me and eight of T. indivisalis, I cannot but be sure 

 that most, if not all, of my T. bifidalis are males, and of my T. indivi- 

 salis, females. The differences in the appearance of the two forms 

 seem after all to be merely owing to the cleft in the wings of one; 

 though the shade of color is not quite the same and the course of the 

 t. p. line constantly differs. The dark colored maculate legs seem to 

 be similar in appearance in both species while the armature seems 

 alike; both forms have a single long spur at the extremity of the 

 middle tibiae. I shall then not be disappointed that the two prove to 

 be sexual forms of one species. Guenee had only males before him 

 with cleft wings, and speaks doubtfully of the probable sexual peculi- 

 arities of the female. If T. bifidalis and T. indivisalis are £ and 9, 

 the sexual secondary characters will be confined to the primaries. 



CLANYMA, Guenee. 

 Two species of this genus are described by Guenee from our Terri- 

 tory and specimens are contained in the collection before me. These 

 are notable from exaggeration of the labial palpi, which, in the female, 

 are thickly scaled and extended forwards and are longer than the 

 head and thorax together ; the 3rd article is held at right angles with 

 the elongated second, small, distinct, subspatulate, porrect. In the 

 male they are thrown backwards over the head and thorax, closely ap- 

 plied and furnished with a large hidden tuft of light-colored hair 

 capable of expansion. 



Clanyma angulalis, Hubner, sp.— % £. — Primaries brownish frosted 

 with pale slightly purplish scales; colors bright. A narrow blackish half-line; 

 t. a. line similar, inwardly oblique, outwardly waved. A minute orbicular dot. 

 Median shade obsolete superiorly, forming an inwardly oblique very promi- 

 nent deep brown shade streak below the disc to internal margin. Eeniform 

 well sized, deep brown, approximate inferiorly to the linear t. p. line, which 

 latter resembles the t. a. line in appearance, a little irregular, projected oppo- 

 site the disc. Subterminal line diffuse, followed by a distinct whitish shade, 

 perpendicular, a little jagged or dentated. Costal region at apices with a brown 

 shade below which, on external margin, is a bright yellowish shade patch. A 

 narrow continued terminal line; the fringes are obsoletely spotted with brown- 

 ish. Secondaries pale ochreous, darker shaded inferiorly, the t. p. line of the 

 primaries continuous. A diffuse subterminal line followed by a whitish shade 

 at the angle. Beneath with powdered dark scales and double lines on both 

 wings; discal dot on secondaries evident. Expanse, 24 to 28 m. m. 



Habitat. — Massachusetts to Alabama.
