114 CLARK — SOME UNDESCRIBED SPHINGIDAE [PB Z.C- 
in phaeton, being 9 mm. in length; they are more slender, and very slightly 
clubbed, while those of the female of phaeton are strongly clubbed, as in the 
male. 
The marginal band of the hind wing in the female of euterpe is less mark- 
edly convex than in the male. 
This sphingid is evidently very rare. Several collectors 
searching for a number of years have failed to rediscover it.
