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



marginal band.

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 2| — 3| 



lines long; wings 8 — 10 lines. 



Walker. 



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^ — 4 lines ; of the wings 10 — 11 lines. 



Hudson's Bay. 



Walker. 



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

 hare 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 tonxjiie is 

 rudimentary ; fore icings xoilh a second marginal branch in the 

 middle of the ctpical 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.
