Differs from the foregoing in that the squammation of the anterior 

 wings, on the upper surface, is largely greenish. Compared with A. 

 Antseiis, this smaller species has quite a distinctive appearance, while 

 my examinations have afforded me but the green powdery scales which 

 cover the anterior wings on their upper surface, as well as the head, 

 thoracic region and abdomen, as a strong specific character, the orna- 

 mentation being remarkably similar in both species.

Amphonyx cluentius, Poey, (Sphinx cluentius. Cramer), is not in- 

 cluded in the present collection, while Dr. Gundlach appears to have 

 sent it from Cuba to Dr. Herrich-Schseffer. 



SPHINX, Linnaeus. 

 While the European Sphinx convolruli, and Sphinx ligustri, must 

 be considered the more typical forms of this genus, I am aware that 

 the material T here include under Sphinx, appears susceptible of dis- 

 tinctive generic separation. The generic term Man'osila Boisd.. used 

 by Mr. Walker and Dr. Clemens for certain of the species, should have 

 the preference over Protoparce Burm., already mentioned in this No- 

 tice, and which contains such discordant material and seems so poorly 

 conceived that it is better entirely neglected. The generically per- 

 fectly distinct species composing the genera Pseud oqyhinx Burm.. and 

 Amphonyx Poey, have, however, been confounded by both Mr. Walker 

 and Dr. Clemens, as congenerical with Sphinx rustica and allies, while 

 the species composing the two former genera, are apparently regarded 

 by these authors as typical of the genus Macrosila. Amphonyx Poey, 

 erected in 1832, has priority over any of Boisduval's MSS. genera 

 made public by Mr. Walker in the Catalogue of the British Museum, 

 and contains perfectly homogenous material, and is, moi'eover. more 

 scientifically correct and better conceived than Macrosila. By amend- 

 in"; Macrosihi, and includintr under that ueneric name, the first three 

 species of Sphinx here enumerated, adding Sphinx quinquemaculata
