"beneath, at the external angle are live silver marginal triangles surmounted udth 

 black r secondaries iinderneath "have a pale tcnrny mar(/inal hand, a marginal series 

 of seven triangular sjxjts cdijcd irlfh Mack.'" ^'^one of these characters l)eLjng to 

 Aphrodite, and unless it be the color — "tawny orange" "and the tawny marginal 

 band" — none belong to C'ybele. 



]\Ir. A. R. (Injte, who spent several months the past year (1807) in examin- 

 ing the 2)rinci])al entomological collections of Europe, informs me that in none of 

 them are these two species separated, sometimes being labeled by one name, some- 

 times ])y the other. 



The description of Cybele by Fabricius is as follows : — 

 "Alls dentatis i'ulvis nipro niiiculatis: subtus niaculis 34 argentcis. 

 Paj)ilio Daphnis. Cram. Ins. 5, fab. 57, fii.'. E. F. 

 Habitat in America. 



Statura praecedentiiim [i. c. Ajjlaja. Aiihrodite, etc.]. Alao omnos dcntatao, lutcae, nigro maculatae. 

 Subtus puncta octo in alis aQti(;i.s et 20 in posticis argentca. Fascia flava in alis postieis ante warginem." 

 This description is correct in the essential particulars, color hdeous, second- 

 aries with a yellow band. The exact number of silver spots is immaterial, as in 

 both S2>ecies they vary. 



The descri2ition of .Vphrodite is as follows : — 

 "Alis dentatis i'ulvis nigro niaculatis: posticis subtus fuscis : inaculis 24 argenteis. 

 Habitat in America nieridionali. 



Medius. Antennae ferrugineae clava nigra, apiee ferruginea. Alae supra fulvae. nigro maculatae. 

 Subtus anticae fulvao, nigro maculatae puncti.«quc quatuor apicis argenteis. Posticae fuscae fascia apicis 

 fiavescente maculisque 24 argenteis." 



Colov fulvous ; fore wing benealh falroiis; hind wings beneath fuscous, that is, 

 black and red. 



This description applies particularly to Aphrodite female. 



I therefore present, for the fir.st time, descriptions and figures of the males and 

 females of both S2)ecies. Cybele is the larger, and the difference in color between 

 the sexes is much less than in A2)hrodite. In the latter tlie male is much smaller 

 in proportion to the female, is brighter colored than Cj'bele, and has very little 

 brown at base of wings. The black markings are noticeably more delicate, the 

 marginal lines on primaries nearer together, more or less excluding the fulvous 

 sjjots Avliich, in Cybele, are distinct along the whole margin. The margin of 

 secondaries also has an edge line like the primaries; the median baml is formed 

 of small crescents, separated by wide spaces and obsolete on costal margin ; and 

 there is no black sj^ace between the costal and subcostal as in Cybele. On the un- 

 der side the silver marginal and costal spots are decided, while in Cybele they are 

 usually wanting, or indicated by a few scales only; the basal C(jlor of secondaries 

 is cinnamon-brown, and the band is more or less encroached on by the ground 

 color ; the pyriform spot of third row is cut by the arc as in Cybele, but the smaller
