PLATE CCCCLXIX. 3 



from which it is to be inferred, that he confidered the firft. of thefe 

 infects as only a variety of S. Convolvuli, and the latter as a diftinct 

 fpecies. We mall not, however, adduce this as a pofitive teftimony 

 that they were in reality different : indeed we fufpect the contrary ; 

 but on a fubject fo ambiguous, we conceive it candid to ftate the ideas 

 of Mr. Driiry, as well as the opinion we ourfelves entertain. 



Since the production of the work to which we laft adverted, 

 Mr. Abbot, an affiduous entomological collector in the province of 

 New Georgia, North America, furnimed feveral of the Englifh cabi- 

 nets with fpecimens of the infects of that particular country where he 

 relided, and among the reft with fome few examples of the individual 

 kind of Sphinx to which our attention is now directed. A feries of 

 drawings by Mr. Abbot, explanatory of the various changes of a felect 

 number of the infects of that part of the globe, were likewife trans- 

 mitted to England about the fame period, one of which exhibited the 

 transformation of this very fpecies. Thefe drawings afterwards patting 

 into the hands of the London bookfellers, were engraven and pub- 

 liflied under the title of Abbot's Infects of Georgia, with obfervations 

 by Dr. Smith. 



Thus it appears, that of the two figures confidered as reprefentations 

 of our infect, one only is certain, and that is the figure included in the 

 laft mentioned publication. The latter we are affured of, not only 

 from an attentive infpection of the original drawings *, but alfo from 

 the individual example delineated in that work, and which differs in 

 no refpect from the infect now before us. This we mention in order 

 to Ihew that our comparifons are deduced with a fufficient degree of 

 certaintv. 



* Thefe original drawings were, in the firft inftance, configned from Georgia by Mr. 

 Abbot to Mr. G. Humphreys, in London, and remained in the poffeffion of the latter 

 fome time. They were executed by Mr. Abbot on coarfe wire-marked paper, and 

 were, more or lei's, dilcoloured and ftained with fea-water, an injury fuftained in the 

 pafiage between America and England, With the exception of tins circumftarice, we 

 have no reafon to diftruft their general accuracy, and that exhibiting the transformations 

 Of our prefect iilfctf had in particular efcaped without any material damage.
