in our opinion, sufficiently with Drury's figure and description to war- 

 runt the assumption that it is the species intended. A comparison of 

 Drury's description will disclose the fact, that the differences presented 

 between the secondaries in Drury's figure and our species can be recon- 

 ciled; there remain, then, but the differing habitat given by Drury and 

 the superior size of his figure. When we remember the frequent errors of 

 the older authorities ;is to the locality of the species they illustrate, we 

 shall err if we accord too much weight to such references. Mr. Grote has 

 commented sufficiently upon the characters of ornamentation which 

 unite the Cuban species and Drury's figure, and we opine, that the 

 name of Sphinx cube7isis, proposed by Mr. Grote for the present spe- 

 cies in the case that Drury's species were eventually more satisfactorily 

 discovered, will not be available. 



SYZYGIA, nov. gen. 



Differing from Diludia, in the shape of the wings and proportions of 

 the corporate parts, the present genus contains apparently two charac- 

 teristic species of the present Family, which have hitherto been referred 

 by authors to Hijloicus and Sphinx. The antennae are very long and 

 massive, and are characteristic. The head is large, as are the eyes, but 

 not so salient as in Diludia and Macrosila ; the prothoras is rather 

 square in front, moderately advanced before the insertion of the prima- 

 ries. These latter are much rounded along external margin ; apices 

 depressed. The posterior tibiae are strongly spurred. The species 

 composing this genus are characterized by their yellowish-cinereous 

 squammation, which readily distinguishes them from the species of 

 Dilndia. 



Our material is too scanty to allow us to eliminate the dissectional 

 characters of this Southern genus, which, as intended here, will be rea- 

 dily recognized. The species are Sphinx Pamphilius Cramer. PI. 394, 

 fig. E, from Surinam, and Sjthinx ufflirtaGvoteSrom Cuba. We give 

 a figure of this latter species, already described by Mr. Grote in his 

 paper on the Cuban Sphingidse, and which will be found to differ suffi- 

 ciently from Cramer's representation of S. pamphilius, as to render the 

 supposition of their distinctiveness a tenable one. 



Daremma repentinas. 



We are indebted to the kindness of Mr. J. W. Weidemeyer for the 

 information that Mr. Walker writes thus concerning Daremma undu- 

 losa, Walk. C. B. M. "This species is a mistake; it has been newly 

 identified as a dwarfed and slightly aberrant specimen of Sphinx 

 Brontes." Since we regard the ^'Macrosila Brontes?" Walker as
