Sphingidae 



SUBFAMILY CH/EROCAMPIN/E 

 Genus XYLOPHANES Hubner 



This genus, which is American, is very large, containing fifty 

 species and many subspecies. Of these species two only are 

 found, so far as is now known, within our territory, though it is 

 possible that a thorough exploration of southern Florida may 

 show that one or two of the species which are found in the 

 Antilles also occur in that State. The student will have no diffi- 

 culty in recognizing the species occurring within our borders by 

 means of the figures which are given upon our plates. 



(i) Xylophanes pluto Fabricius, Plate IV, Fig. 9, $ . (The 

 Pluto Sphinx.) 



Syn. bcerhavice Fabricius; crcesus Dalman; thorates Hubner; eson 

 Walker 



This beautiful hawkmoth, which is very common in the 

 Antilles, ranging southward to southern Brazil, occurs in 

 southern Florida. The larva feeds upon Erythroxylon. 



(2) Xylophanes tersa Linnaeus, Plate II, Fig. 13, & . (The 

 Tersa Sphinx.) 



This common and easily recognized species has a wide range, 

 occurring very rarely as far north as southern Canada, thence 

 southward to Texas and Mexico, and as far south as northern 

 Argentina. The larva feeds on Bonvardia, Spermacoce, and 

 Marietta. 



Genus CELERIO Oken 



Head of moderate size. Eyes hemispherical, not prominent. 

 Antennae distinctly clavate, and armed at the tip with a minute 

 hook. The thorax is stout, projecting for about one-third of its 

 length beyond the insertion of the fore wings. The abdomen 

 is conic, untufted, produced more or less at the tip, and project- 

 ing for half its length beyond the hind margins of the secondaries. 

 The fore wings, which have eleven veins, are produced at the 

 apex. Their outer margin is slightly and evenly bowed out- 

 wardly. Their inner margin is very slightly sinuate. The hind 

 wings have their outer margin evenly rounded, except at the 

 extremity of vein 1 b, where they are slightly produced. The 

 genus is well represented in the Old World, and there are several 

 South American species. Only two species occur in our territory.
