we agree with that eminent Entomologist that the two species are quite 

 distinct. Prof. Burmeister confounds the two as sexes of one species, 

 adopting Cramer's error. Mr. Grote's doubtful citation of Westwood's 

 Ed. Drury is incorrect, and, so far as we are aware, the name of Grameri 

 is first proposed by ^Menetries, whose remarks we cite : " Cramer a figure 

 PI. 394, D, le Ficm male, et il y rapporte comme la femelle la figure 

 246. E, Cest a tort je crois qu'on a adopte son opinion ; I'Academie 

 possMe les deux sexes de chacun de ces papillons, qui m'ont paru con- 

 stituer deux especes difFerentes. Ainsi pour nous, la figure de Cr. 394, 

 T>, represente le veritable Firm Cr., tandis que la figure 246, E, ap- 

 partient a une autre espece que nous avons nomm^e Crameri." 



Smerinthus geminatus. 



The synonymy of this species, as given by Mr. "Walker and Dr. Cle- 

 mens, seems to us quite erroneous. We find no description of this 

 species as " Sphinx geminata" by Say, Avho, so far as we are aware, 

 does not mention the species except in the first volume of the " Ame- 

 rican Entomology." Smcrinthus Jamnicmsis Drury sp. seems to us, 

 judging from Drury's figure and description, quite distinct from the 

 northern species from the Atlantic District, while we have satisfied 

 ourselves that S. a-rlsii Kirby is also distinct from its near ally — S. 

 gemiiKitus. 



Smerinthus pavoninas. 



A hitherto unidentified, and, since Greyer wrote, unnoticed species of 

 Smpriiit/iHs.vfh'ich the author mentions having received from Penn.syl- 

 vania. It seems allied to S. excaratus, while Greyer compares it with 

 the European S. occllufus; compared with the former, Geyer's figures 

 offer too many points of distinctiveness to allow us to consider it as the 

 species intended. 



Smerinthus modestus. 



The genus Po/j/jjtj/chus was erected by Hiibner in his "Verzeich- 

 ni-ss," for thoj-e species of ASmcrinthua which may be shortly character- 

 ized as possessing unocellated and differently shaped secondaries. 

 As it stands, it contains dissonant material and cannot be accepted. 

 Since we are disposed, generally, to regard the species first cited under 

 Hiibner's genera, as typically intended, we find in the present instance, 

 that the Asiatic Sj^hinx dmfatus Cramer, offers structural features 

 which seem to authorize its generic separation from Smerinthus Latr. 

 as typically intended, (with which latter, Faonlas Hiibner is syno- 

 nymous) and that to this species, Hiibner's genus may be restricted. 

 On comparing ^S". modvaius Harris with the European S. pojjuli, we
