Remarks on the Sphingidce of Cuba. 199 



of the authors above cited (Philampelus jussieuce Clem.),- is 

 described as belonging to the distinct species now named Phi- 

 lampelus linnei / nor are Cramer's two figures kept separate. 

 So that, in view of this confused synonymy, the observation of 

 Dr. Clemens, that he is disposed to place the true P. vitis 

 {P. jussieuce, "Walk. Clem,), as a " variety," is capable of an 

 explanation ; in reality, the two species are perfectly distinct 

 and readily distinguishable.

Differs from the typical species of the genus in the shape of 

 the wings ; the apices of the primaries are roundedly exserted, 

 external margin somewhat irregular. More olivaceous and 

 smaller than P. lusca. The paler transverse lines on the upper 

 surface of the anterior wings are straight ; a very prominent, 

 whitish, apical streak extends downwards, obliquely, to first 

 median nervule. Secondaries full ; external margin rounded, 

 excavate before anal angle, latter hardly so prominent as in P. 

 lusca. Above anal angle some paler scales, divided centrally 

 by a narrow' darker line ; internal margin clothed with yellow 

 scales. The yellow costal patch does not extend as a band 

 across the middle of the wing, but is spread somewhat dif- 

 fusedly, crossed by the darker clothed nervures, to the base of 

 the wing. Abdomen somewhat fusiform, with paler marginal 

 scales on the segments posteriorly. 



Expanse (female), 2.30 inch. Length of body, 1 inch. Num-
