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 Linnseus, Plate III, Fig. 1, $. (The Vine 
Sphinx.) 
Syn. hornbeckiana 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 Drary (non Linnseus); jussience Hiibner; strigilis Vogel. 
The caterpillar is reported as feeding upon Jussieua in the 
tropics. In our territory it feeds upon various species of Viiacece. 
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. 11, $. (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 7 the south to the banks of the 
St. Lawrence, a thousand leagues, across rivers, plains, and 
mountains.
