542 PROCEEDINGS OF THE ACADEMY OP 



Arttia rubricosa : Harris, Ins. Mas. 2d ed. 274. Fulvous or reddish brown . 

 Antennae fulvous, blackish on the sides. Fore wing sometimes with a brown 

 discal spot. Hind wings more or less red, with a more or less distinct margi- 

 nal black band, sometimes absent, and sometimes with a dark brown discal 

 dot. 



Fore wings with a second marginal nervule on the middle of the apical. 

 Variety ? Yellowish. Fore wings without discal dot. Hind wings with a 

 discal dot and rather broad, distinct dark brown marginal band. 



C. brevicornis, Walker, 536. Fawn color or luteous fawn color. An- 

 tennae 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^ 3i lines long : 

 wings 8 10 lines. 



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 com- 

 bined 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. 



111., Mr. Kennicott. 



C. ferruginosa , Walker, 535. 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 3J 4 lines ; of the wings 1011 lines. 



It is possible this insect may be the rubricosa of Harris. I have specimens 

 which agree in general with Mr. Walker's description, but they possess 

 noticeable differences in structure as compared with the others described pre- 

 viously. 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 ferruginous, 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. 



My own impression is that rubicundaria of Hiibner and rubricosa of Harris 

 is a variable insect, and that ferruginosa of Walker, and perhaps brevicornis, are 

 not true species. I am much more uncertain, however, respecting the latter 

 than the former. 



*C. cupraria, Walker, 536. Testaceous. Fore legs mostly brown. 

 Wings slightly rosy testaceous, subhyaline, with a slight cupreous tinge 

 towards the tips. Length of the body 3 4 lines ; of the wings 9 11 lines. 



Jamaica ? S. America. 



*C. laeta. Lithosia laeta, Boisd. Guer. Icon. Reg. An. Ins. pi. 88, f. 6, 

 p. 519. C. laeta, Walker, 537. 



Grayish black. Tongue testaceous. Abdomen red, with a black stripe 

 which is broader beneath than above. Fore wings red along the costa. Hind 

 wings red, with a broad grayish black border. Length of the body 3 lines ; of 

 wings 9 lines. 



N. America ? 



Atolmis ? Hiibner. 



Fore wings rather elongated, subelliptico truncate. Disk rather narrow 

 closed by a very faint vein. Subcostal vein remote from the costa, with two 

 marginal nervules from near the middle of the disk rather erected, and another 

 exterior to the disk, between it and the furcate apical nervule. Thesubcosto- 

 inferior and discal from a short common stalk. Median 4-branched, the pos- 

 terior remote from the others, arising interiorly to the first marginal nervule.
