The remaining genera, being doubtful Sphingidce, need not be considered. 



The species which has the greatest range is Chcerocampa celerio. This insect is found 

 throughout the Old World ; it is very rapid and indefatigable on the wing, and is not 

 unfrequently caught on board ship out of sight of land. Its food-plant is the vine.
