12. Corrections and Addenda to certain Papers on Lepidoptera 

 published during the years 1865-66; with Additional 

 Notes on some of the Species described. By Arthur 

 G. Butler, F.Z.S., Assistant, Zoological Department, 

 British Museum. 



I regret to find that, having relied too much upon the complete- 

 ness of a recently published list of Diurnal Lepidoptera, I have, in 

 several of my papers, overlooked species. This error has in some 

 cases been the means of leading me to redescribe insects ; and to 

 these I propose in the present paper to restore their rightful names. 



As I have lately had the advantage of seeing several types, and 

 additional specimens, of insects which I have mentioned, I am now 

 enabled to correct or add to any remarks which I may have made 

 with regard to them. 



Papilio. 



In a paper published in the 'Annals and Magazine of Natural 

 History,' June, 1866, "On the Identity of certain Species of Lepi- 

 doptera," I supposed that P. caudius might possibly be an Ama- 

 zonian form of P. aryentus. However, I have since detected a male 

 of P. caudius amongst our specimens of P. torquatus : it differs from 

 the P. torquatus of Brazil in having a broader subapical band on the 

 front wings, and greenish instead of yellow submarginal spots on the 

 hind wings ; the outline of the wings, too, with the exception of the 

 tails, exactly corresponds to the outline of the wings of P. caudius ; 

 therefore, although very closely allied, I think these two species may 

 stand. Although the sexes in this group differ considerably in colo- 

 ration, the outline of the wings is almost identical. 



Hesperocharis. 



I have seen the type specimen of Hesperocharis graphites. Bates, 

 in Mr. Salvin's collection, and I must confess that it seems to me
