contiguous to subterminal band, bent before anal angle ; a broad, sub- 

 teruiinal black baud, widest at costa, narrowing to anal angle, before 

 which it is suddenly constricted; terminal space narrow, nowhere 

 pinkish, obscure brownish; external margin more rounded than in P, 

 vitis. 



As regards Philampelus Ilornheclciana, we are indebted to Dr. 

 Packard and Mr. Sanborn for the information that a thorough search 

 into Dr. Harris' collection, kindly undertaken at our request, has failed 

 to detect any specimen resembling Dr. Harris' description of this spe- 

 cies, or so labelled. While Dr. Harris' description would seem to imply 

 that P. Linncl nob. is intended, the description of the anterior wings 

 does not correspond, while that of the posterior wings must be incom- 

 plete, if it is to be taken literally. The description of the corporal parts 

 quite nearly correspond with our specimens of P. Liiinei, but these 

 have great coincidence in the present genus. Warned by the disco- 

 very of P. afi-i'mius, that there pi'obably exist more species belonging 

 to this genus than at present known, we conclude that perhaps Dr. 

 Harris' species may be re-discovered at some future day, while this has 

 been an incentive to us to endeavor to fix the limits of P. vitis since 

 that species has been so often mistaken by authors, as will be seen by 

 the digest of our synonymy, that we know of no case in this Family where 

 the opinions are so conflicting and the matter of references so intricate. 

 We trust that we have shed some light on a subject, which, adopting 

 the synonymy of Mr. Walker and Dr. Clemens, is simply incomprehen- 

 sible, and could hardly lead any Entomologist into ought but error. 

 All the descriptions and figures we quote in the synonymy of these 

 species have been critically examined, and, since in this case the ac- 

 knowledged insufficiency of the earlier Latin diagnosis is strengthened 

 by a figure, which, however gross, bears a distinctive coloring which 

 appears to us to afford a strong specific character, we can come to no 

 other conclusions than those we have here presented, independent of 

 the concurrent te.stimony of so many of the earlier authorities on Ame- 

 rican Lepidoptera. 



Philampelus lycaon. (Plate .3, fig. 4, 9-) 



We refer to Mr. Grote's paper for remarks on this species as well as 

 on P. satellitia. Although Cramer's fi<2;ure of .S*. licaon wants the anal 

 roseate patch, still this is vaguely indicated in the description, which 

 is short, and reads as follows: " Ce Sphinx Entier tres rare (Sphinx 

 Legitima) est en-dessous de couleur minime et vers les pointes des 

 ailes iuferieures de couleur rousse." There is, perhaps, a third species
