Species peculiar to California 



so far as known to me. 



Hemaris palpalis. 



thetis. 



Euproserpinus phaeton. 

 Arctonotus Incidus. 



Lepisesia darltiae. 

 Smerinthus ophthalmicus. 

 Hyloicus sequoiae. 

 Sphinx perelegans. 



These concluding geographical lists will at least give a 

 general idea of the distribution of certain forms of North 

 American Hawk Moths. 



The Spliingidae are probably not represented in Labrador. 

 In Newfoundland S. canadensis occurs; the species of the 

 highest range to the north are probably Hemaris uniformis, 

 Deilephila cliamaenerii and lineata, Smerinthus cerisii, JEUenia 

 bombycoides, together with this species of Sphinx. No Hawk 

 Moths fly in Iceland ; the family ceases to exist, probably 

 before any other of the larger families of Moths, on the way 

 to the Pole. In Upper Canada most of the species of the 

 Middle States may be found. It is in the tropics, under a 

 warm sun and surrounded by a various flora, that the Hawk 

 Moths reach their highest development in kinds and numbers. 

 Our largest species is Ampltouyx antaeus, the smallest, 

 Euproserpinus phaeton. Our finest northern form (with a 

 wide range) is Triptogon modesta, somewhat inappositely 

 named, but varying greatly in size and depth of color. 



Besides the special Authors cited, we are indebted to 

 Prof. C. V. Eiley for some exquisite drawings of larvae, to 

 Prof. Saunders and Roland Thaxter for descriptions of larvae, 

 while Mr. W m - Beutenmiiller jr., has largely added to our 

 knowledge of their food plants. The Rev. Mr. Hulst, Prof. 

 Lintner, Mr. S. Lowell Elliot and Mr. S. H. Scudder have also 

 made valuable observations on their transformations and 

 immature stages, while Prof. Alex. Agassiz and D r - Wittfeld 

 have encreased our information as to the species inhabiting 

 the Florida Peninsula.
