The remaining genera, being doubtful Sphingide, need not be considered. 
The species which has the greatest range is Cherocampa 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.
