AMERICAN LEPIDOPTERA. 199 



Third : " the words glauc-ce atriga punctorum in'grorum twice re- 

 peated ******* also determine this C-aureian." 

 To the above it may be answered : 



I. Fabricius has ia do instance given America as the habitat of his 

 insect, but distinctly says of it " habitat in Asia." Before charging 

 him with the grave error of assigning to one quarter of the globe 

 what really came from the very opposite, there certainly should be 

 stronger evidence of its American origin than a casual reference to 

 Cramer's figures. ThcvSe figures are so coarsely executed that it is 

 proposed by Mr. Edwards to reject them : the description (if the few 

 words relating thereto ujay be so called) is most indefinite; and the 

 author expresses a doubt whether, although sent to him from Jnmaica, 

 it may not be the same as another species "represented on Plate V, 

 fig. E, indicated as having come from China" (cited by Godart, p]nc. 

 Meth. p. o04, as Vanessa Progiie). Even if we were to assume with 

 3Ir. Edwards the identity of the C-aureum of Fab. and of Cramer, the 

 species of the former would not be determined thereby, for there is a 

 strong probability that the latter does not represent our interrogationis, 

 but will prove to be a southern form of Grapta, as yet unnamed.* 



II. The inference from "?H'??i.»s a^'/ijs * * * C-rt?<reMv?i" might have 

 been properly drawn, if it could be shown that there are only these 

 two Graptae closely resembling one another, either now known or here- 

 after to be discovered. On page 7 of his paper, Mr. Edwards notices 

 '• the remarkable resemblance between these species and G. comma." 

 On the same page, he indicates a fourth species, Drt/as, nearly allied. 



."Mr. Scudder, in the C-aurtum of Abb. Sm. and Cramer has detected 

 a fifth species. The careful study which our Diurnals have of late 

 years received, has in several instances revealed undoubted specific 

 characters, v.'here formerly only varietal difi'erences were thought to 

 exist. Thus in (irapta, during the last eight years, from three old 

 species, five others have been educed, while the same number of spe- 

 cies of Nisoniades, have rewarded rigid scrutiny with an addition of 

 six new forms. 



In view, therefore, of the new species recently described, and the 

 probability of other Nurth American ones yet undetected, it must be 



.*Since the above was written, it appears from a notice in the Proceedings of 

 the l^oston Society of Natural History, vol. xiii, p. 27fi, that Mr. ScucWor, from 

 material recently obtained, has determined this species to be identical with 

 thatof Abb. Sm., aud proposes for these forms the name of G. Crameri. Speci- 

 mens of tiie species have bean received by Mr. S. from Texas and other south- 

 ern districts. If Fabricius is correct in his reference to Cramer's figures, then 

 it appears that his C-aurcic-n is e^uivaleut to this newly detected species.
