As we do not possess examples of Y. progenies fi'om the 

 West Indies to compare with the Amazonian specimen, 

 and as the latter is also a good deal rubbed, I cannot be 

 certain of the identification ; the markings are, hoAACA-er, 

 A-ery like those of the figure by ]M. Guenee. The species 

 has more the aspect of a Deltoid than of a true Xoctuid, still 

 (for couAcnience sake) I proA'isionally incorporate it in 

 this paper, folloAving the aiTangement of 5l. Guenee, 

 adopted by ]Mr. AValker.
