In 1797, Abbot (Insects Georgia), figured without description as 

 C-aureum the species before given by Cramer. 



Mr. Lintner determines that both Cramer's and Abbot's figures rep- 

 resent the male of that one of these two species which has a red upper 

 surface and much falcated forewings, in contradistinction to that with 

 black hind wings, and slightly or not at all falcated forewings, which 

 he calls Umbrosa. To avoid confusion, I will, for the present, speak 

 of these as C-aureum (Fab.) and Umhrosa. 



At first glance Abbot's figures seem to represent Umhrosa. But 

 after careful comparisons with many individuals of both species, I think 

 Mr. Lintner's conclusions correct. There is a great variation. Some 

 Interrofjationh have very dark brown hind wings, and may well have 

 stood for Abbot's figures, which are coarsely executed. The outlines 

 of both wings and falcation of fore wings, as Mr. Lintner points out, 

 are those of C-aiirenm, not Umhrosa. On the under side the coloring 

 is faithful to neither but nearest C-aureum. The same remarks will 

 apply to Cramer, whose figures, also, are very coarse. In fact, nothing 

 would be lost by rejecting all these figures. 



In 1798, Fabricius (Supp't. p. 421), for the first time mentions and 

 describes P. Iiiferrogatlonis, viz; "alis caudatis fulvis nigro maculatis, 

 suhtus (jhi\icis: striga punctorum nigrorum, posticis C-aureo notatis. 



Habitat in America boreali. 



Nimis afiinis P. C-aureo at pauUo major et alae suhtus glaucse striga 

 punctorum n igrorum.^' 



Wings tailed, fulvous, spotted with black, beneath glaucous (i. e. a blue or green 

 inclining to grey or white) with a transverse band {striga) of black points.* ••■■ * * 

 Extremely like P. C-aureum but a little larger and the wings beneath glaucous 

 with a transverse band of black points. 



Now Fabricius could not have said that his Interrogationis was "ex- 

 tremely like" Angelica Cramer, (that is, C-aureum, Linnaeus,) for as 

 stated, the two difi"er materially and unmistakably. 



But the words gJaucse, striga punctorum nlgrorum, twice repeated, 

 mark the importance attached to those characters. They were in fact 

 the characters relied on as at once determining the new species from his 

 C-aureum, thereby also determining this C-aureum itself, and with the 

 words jMiuUo major apply completely to the female of Umhrosa. This 

 alone of the males and females of the two species can be called glau- 

 cous, that word well expressing the color by which the wings are suf- 

 fused. To either sex of C-aureum the worxl is wholly inapplicable, 

 the male bein"; brown in varied shades and the female brown sufi'used
