AMERICAN LEPIDOPTERA. 317 



codeiicc in the tiiue of appsarauce of the summer brood of the former, 

 of not less than two weeks. Its rarity is shown by the above collections 

 made from different hop yards, as well as by the fact of its falling so 

 very seldom in the hands of the collector. Besides the above speci- 

 mens, but one other has ever been taken by me. 



vSince the precedinp; pages were written, it has been represented to 

 me that unihrosa is idoitical with the C aurawm of Fabricius. A care- 

 ful examination of the Fabrician descriptions of C. aureum and uiter- 

 ro'idtionh has shown me that neither can be regarded as synonymous 

 with iimJ>ri>xa; they are as follows:

From the citations by Fabricius of Linnreus and Cramer, it appears 

 that his C-aureiim was identical or supposed to be the same with the 

 Asiatic species (Chinese, Cramer). This species according to Godart 

 ''resembles strongly jjolychloros on the upper side. The underside of 

 its wings is obscure towards the base, yellowish towards the extremity, 

 with a golden C, or rather silver, on the disc of the inferiors. The up- 

 per side of most of the females, presents between the middle and the 

 posterior border, five bluish spots, of which three are on the superior 

 wings and two on the inferiors." To this species are referable, FaplUo 

 AiKj'Ura Cramer. Papil. pi. 388, figs. Gr, H, and Papilio Anjelica 

 Herb^t, Papil. tab. 100, figs. 3, 4. 



In elucidation of the error of Fabricius, Grodart's description and syn- 

 onymy of interrogationis, is herewith presented, from Encycl. Method.
