Corrections and Addenda to certain Papers on Lepidoptera published during the years 1865-66; with Additional Notes on some of the Species described. By A R T H UR G.

I regret to find that, having relied too much upon the completeness 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 Lepidoptera," I supposed that P. caudius might possibly be an Amazonian form of P. argentus. 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 coloration, 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 |
