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. 
(11) 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 Neumoegen. 
Form coloradus Smith, Plate IV, Fig. 3, $ . (The Colorado 
Sphinx.) 
Rothschild & Jordan recognize two forms of this species, H. 
dolli dolli Neumoegen, 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 Boisduval, Plate V, Fig. 8, $ . 
(The Sequoia Sphinx.) 
Syn. conifer arum 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.
