308 LEPIDOPTERA OF NORTH AMERICA. 



wings with a discal dot and rather broad, distinct dark brown 



marginal band. 



Pennsylvania. 



Clemens. 



2. C. brevicornis Walker, 536. See p. 255. 



Fawn color or luteous fawn color. Antennas black, short. 



Abdomen rose color. Fore wings rosy beneath. Hind wings rose 



color, with an indistinct and sometimes quite obsolete brown stripe 



in the hind border, and a brown dot in the disk. Body 2J — 3^ 



lines long ; wings 8 — 10 lines. 



Walkee. 



I have specimens which correspond very nearly to the above 

 description. The anterior portion of the body is luteous, as are 

 the fore wings, but combined with a reddish hue. Hind wings 

 cinnabar red, without marginal band or discal spot, and in one 

 specimen the terminal joint of the palpi is blackish. 



Illinois, Mr. Kennicott. 



Clemens. 



3. C. ferruginosa Walker, 535. See p. 255. 



Ferruginous. Abdomen pale ferruginous, with a row of dorsal 



black dots. Hind wings pale ferruginous, with a blackish dot in 



the disk, and two or three blackish spots along the border. Length 



of the body 3 J — 4 lines ; of the wings 10 — 11 lines. 



Hudson's Bay. 



Walker. 



It is possible this insect may be the ruhricosa of Harris. I 

 have specimens which agree in general with Mr. Walker's descrip- 

 tion, but they possess noticeable differences in structure as com- 

 pared with the others described previously. In these the tongue is 

 rudimentary ; fore wings with a second marginal branch in the 

 middle of the apical nervule. In every other particular the struc- 

 ture conforms to that of the genus. These differences may be 

 sexual. In ornamentation they are reddish-brown, scarcely ferru- 

 ginous, and in addition to the discal dot, have a rather faint dark 

 brownish band crossing the nervules. Hind wings rather paler 

 than the fore wings, one specimen with a blackish discal spot, the 

 other without it, and faint blackish spots along the margin near 

 the inner angle.
