Sphingidse 
specimens represent an extreme variation of the very variable 
L. coniferarum. 
SUBFAMILY AMBULICINAE 
Genus PROTAMBULYX Rothschild & Jordan 
This genus is represented in our fauna by a single specie^, 
which occurs as a straggler into the extreme southern limits of 
the United States, and is represented in Florida by a local race, 
to which Rothschild & Jordan have given the subspecific name 
of carteri in honor of Sir Gilbert T. Carter, the Governor of the 
Bahamas, an ardent lepidop- 
terist. From A. strigilis Lin¬ 
naeus, which is represented in 
the annexed cut, A. carteri 
may be distinguished by the 
fact that the fore wing is 
broader, less deeply excavated 
below the apex, and by the 
further fact that most of the 
lines and markings on the 
upper side of the wings and 
all the markings on the lower 
side of the wings are ob¬ 
solete. While strigilis has 
not yet been reported from 
our territory, except as represented by the form above men¬ 
tioned, it is highly probable that it will be found to occur in 
southern Florida. 
Genus SPHINX Linnaeus 
The type of the genus Sphinx of Linnaeus is unquestionably 
the well-known European species named by the immortal Swede 
Sphinx ocellata. With this species the following two species, 
which have for many years been referred to the genus Smerinthus 
Latreille, which sinks as a synonym, are strictly congeneric. 
(i) Sphinx cerisyi Kirby, Plate VII, Fig. 3, $. (Cerisy’s 
Sphinx.) 
The larva feeds upon different species of willows. There are 
several forms, or subspecies, whicn have received names, and
