Sphingidae 



The larva of this hawkmoth feeds upon various rosaceous 

 plants, as the wild rose and the crab-apple. It ranges over the 

 Atlantic region from southern Canada and New England to 

 Georgia, and westward to Colorado. 



(n) Hyloicus luscitiosa Clemens, Plate V, Fig. i, $. 

 (Clemens' Hawkmoth.) 



The caterpillar feeds upon various species of willow. The 

 insect occurs from Canada to the Carolinas, and westward 

 through the eastern portion of the valley of the Mississippi. 



(12) Hyloicus drupiferarum Abbot & Smith, Plate VII, 

 Fig. 7, $ . (The Wild-Cherry Sphinx.) 



This common and easily recognizable species ranges over the 

 whole of temperate North America from the Atlantic to the 

 Pacific. The caterpillar feeds upon various trees and shrubs, but 

 seems in the Middle Atlantic States to prefer the wild-cherry as 

 a food-plant. 



(13) Hyloicus dolli Neumcegen. 



Form coloradus Smith, Plate IV, Fig. 3, ? . (The Colorado 

 Sphinx.) 



Rothschild & Jordan recognize two forms of this species, H. 

 dolli dolli Neumcegen, and H. dolli coloradus Smith. The 

 latter we figure. The former is prevalently lighter in color than 

 the form coloradus. The insect ranges from Colorado to 

 Arizona. 



(14) Hyloicus sequoiae Boisduva'l, Plate V, Fig. 8, $ . 

 (The Sequoia Sphinx.) 



Syn. coniferarum Walker (partim). 



The early stages of this insect we do not remember to have 

 seen described. It occurs on the Pacific coast. Boisduval's type 

 was found sitting on the trunk of a red-wood tree (Sequoia}. 



(15) Hyloicus pinastri Linnaeus. (The Pine Sphinx.) 



Syn. saniptri Strecker. 



The late Dr. Strecker reported this species as having been 

 found by him in the vicinity of Reading, Pennsylvania, on one or 

 two occasions. No one else has taken it, so far as is known. 

 It is common in Europe, and has often been figured by European 

 writers. 



Besides the species above given, there are one or two other 

 species of the genus found in our territory.
