Notes on GRAPTAS C AUREUM and INTERROGATIONIS.-Fab. 



By WM. II. EDWARDS. 



Until the publication of Mr. Lintner's paper in Trans. Amer. Ent. 

 Soc, 18G!3, these two species had been treated by late authors as 

 identical, some describing one and some the other, or sexes of 

 either, under the names C-aureum and Interrogationis indififcrently. 

 Our collectors had accepted without much question, the statement of 

 Boisduval and Leconte, which is in effect, that although there would 

 seem to be more than one species, yet as the caterpillars are the same, 

 the butterflies must be the same also. 



The first mention of a Papilio G-aurcum is in Linnaeus, Syst. Nat, 

 1760, I, p. 477, as follows; "C-aureum. P. N. alis angulatis fulvis ni- 

 gro maculatis; posticis subtus C-aureo notatis. Habitat in Asia." 



This species is now recognized as equivalent to Angelica, Cramer, 

 pi. 388, an Asiatic species found in India and Japan, materially and 

 unmistakably differing from any American Grapta. Though, be it 

 noted that the above indefinite description applies to either of our 

 large species, or indeed, excepting the silver mark, to any Grapta then 

 or now known. 



In 1775, Fabricius, Syst. Ent. page 500, describes C-aureum nearly 

 in same words; viz, "P. alis dentato-caudatis, fulvis, nigro-maculatis; 

 posticis subtus C-aureo notatis. Habitat in Asia.'' and refers to Linnaeus. 



In 1781, Fabricius, Sp. Ins. 11, p. 94, again describes G-aureum in 

 same words, with same reference to Linnaeus and habitat, but refers 

 also to Cramer, 11, pi. 19, fig. E, F. Cramers figures purport to repre- 

 sent an American species, which may properly be considered as the one 

 had in view by Fabricius, althoiigli tliere was error in his reference to 

 Linnaeus and in his habitat, caused naturally by the vague description 

 of Linnaeus.
