posterior wings are paler, the yellow band not so distinct and macular 

 as in that species. 



From a figure of C. falro Walk., executed under the superintendence 

 of Mr. Walker, and for permission to examine which I am indebted to 

 Mr. S. Calverley, the present species widely diifers. In the Mexican 

 species the anterior wings are more falcate, the external margin greatly 

 straighter, while the terminal space is much paler, enclosing a very dis- 

 tinct black band, which dilates triangularly on internal margin ; the 

 external margin of posterior wings is also much straighter. the yellow 

 color more largely predominates, the black space in the centre of the 

 wing being reduced to a narrow band ; the abdominal ornamentation 

 also differs, while the species is much larger than its Cuban ally, the 

 latter more nearly allied to C. tersa.* 



I dedicate this species to the Entomologist and my kind friend, Cole- 

 man T. Robinson, of New York City. •

DEILEPHILA, Ochsenheimer. 

 Deilephila Calverleyi, u. s. (Plate 1, fig. 4, % .) 



Allied to Di'dcpli'da. lineata, and with a certain resemblance to Deile- 

 phila chamsenerii. Anterior wings dull brownish, very faintly olivaceous. 



*"Dass die von mir beschriebene Art (Corr. Bl. 1863, p. 148) als Varietat 

 hieher gehoren solle, wie H. G. raeint, kann ich nieht glauben, obgleich ieh die 

 richtige Bestimniung nach Walker nieht verbiirgen kann." H-S. C. B. 1865, p. 

 58. Mr. Gundlaeh's supposition I regard, with Dr. Herrich-Schreffer. as deci- 

 dedly erroneous.
