Sphingidae 



specimens represent an extreme variation of the very variable 

 L. conifer arum. 



SUBFAMILY AMBULICIN/E 

 Genus PROTAMBULYX Rothschild & Jordan 

 This genus is represented in our fauna by a single species, 

 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. sirigilis 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 fiict that most of the 

 lines and markings on the 

 upper side of the wings and 

 all the markings en 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 oceUafa. 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, which have received names, and
