Sphingidae 



Professor C. V. Riley, "Missouri Reports," Vol. Ill, p. 75, is most 

 excellent. The figure which we give is taken from that Report. 

 The insect ranges over the entire United States from the 

 Atlantic to the Pacific, and from southern Canada to northern 

 Mexico. 



(3) Pholus vitis Linnaeus, Plate III, Fig. 1, $ . (The Vine 

 Sphinx.) 



Syn. hombeckiana Harris; linnei Grote & Robinson; fasciatus Grote 

 (partim). 



The true Pholus vitis, which we figure in our plate, may 

 easily be distinguished from its near ally, Pholus fasciatus 

 Sulzer, by the absence of the pink outer marginal area on the 

 upper two-thirds of the secondaries, by the inward prolongation 

 of the large black spot near the inner margin of the secondaries 

 into a well marked mesial band, and by its larger size. It 

 occurs in Florida and in southern Texas and Arizona, whence it 

 ranges southward over wide areas. 



(4) Pholus fasciatus Sulzer, Plate III, Fig. 2, $ . (The 

 Lesser Vine Sphinx.) 



Syn. vitis Drury (non Linnaeus); jussteiice Hubner; strigilis Vogel. 



The caterpillar is reported as feeding upon Jussieua in the 

 tropics. In our territory it feeds upon various species of Vitacex. 

 It is quite common in the region of the Gulf States and south- 

 ward, and sometimes is even taken as a straggler as far north as 

 Massachusetts. 



(5) Pholus labruscae Linnaeus, Plate III, Fig. II, $. (The 

 Gaudy Sphinx.) 



Syn. clotho Fabricius. 



This beautiful creature is characteristic of the tropics, where 

 it is not uncommon. It occurs quite abundantly in southern 

 Florida and along the borders of the Gulf, and throughout the 

 Antilles, Central, and South America. Specimens, in spite of 

 the subtropical habitat of the species, have been taken in Canada, 

 illustrating the wonderful power of flight which is possessed by 

 these insects, the frail wings of which bear them in the dusk 

 of evening, during the few days of their existence in the winged 

 form, from the orange-groves of the south to the banks of the 

 St. Lawrence, a thousand leagues, across rivers, plains, and 

 mountains.
