Sphingidae 
SUBFAMILY CH^ROCAMPIN/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. 
(1) Xylophanes pluto Fabricius, Plate IV, Fig. 9, $ . (The 
Pluto Sphinx.) 
Syn. bosrhavice 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 Bouvardia , Spermacoce , and 
Manetta . 
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/ore 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.
