last ranging through Mexico into Arizona certainly indicate their ancient 

 home and that they have come to us both from the south-east and south- 

 west, from the South American tropics. Ampelophaga comprises three 

 species ; one ranging from Florida to Canada and west to Iowa, and 

 another from Georgia to Canada and west to Missouri and Iowa, while 

 the third extends from Brazil throughout the Atlantic Coast States and 

 west to the Mississippi valley. Two genera, Cocytius and Pseudosphinx, 

 have one species each, the former occurring in the Antilles and Florida 

 and the latter extending from South America through the Antilles into 

 Florida. The genus Dilophoiiota, seven species, every one of which 

 occurs in South America and Florida, some occasionally farther to the 

 northward. The two genera, Catttethia and Di/ndia, containing respec- 

 tively one and two species, all three of which are found in the Antilles and 

 Southern Florida. Phlegethontiiis contains five species ; one ranging 

 over the United States and Canada, and another from South America, 

 Mexico and West Indies, northward over the entire United States into 

 Canada \ a third being found in South America and the West Indies, 

 northward as far as New York ; the fourth extending from Brazil to 

 Canada and over the United States to the Pacific coast aixi in Hawaii, 

 while the fifth is the cosmopolitan species, P. convolvuli, which ranges 

 over the British Islands, Europe, Asia, Africa, Australia, New Zealand 

 and the entire Southern States. Dr. Dyar considers the last two as one, 

 the latter species. The genus Sphinx has nineteen species and two 

 doubtful. Omitting these doubtful species, two cover the entire United 

 States from Florida to Canada and westward ; two from Georgia to 

 Canada and west to Mississippi River States ; one from Florida to Canada 

 and west to Mississippi River States ; two range over the Atlantic States 

 east of the Mississippi ; one is found from New England to Newfoundland 

 and west to Ohio; two cover the Southwestern States by their distribution; 

 one the Southern States ; one is known from Missouri only ; one each 

 occur in Texas and Colorado ; one in Arizona, and one extends from 

 Arizona to Utah ; two are confined to California, and the last ranges over 

 the Western and Rocky Mountain States, the genus together showing 

 about an equal number of species that can be accredited to the south-east 

 and south-western diffusion. Doiba, with one species, occurs from Florida 

 to Canada and west to Iowa, while Chlcenogramma., also with a single 

 species, is known from Georgia to Canada and west to States bordering the 

 Mississippi River ; Ceratomia has four species, two ranging from the 

 Carolinas to Canada and west to States bordering the Mississippi ; one
