Sphingidae 
(2) Ceratomia undulosa Walker, Plate VI, Fig. 7, ? . (The 
Waved Sphinx.) 
Syn. repentinus Clemens; brontes Boisduval (non Drury). 
This hawkmoth, which may easily be separated from its 
congeners by its lighter color and the distinct wavy maculation 
of the. fore wings, lives in the larval stage upon the ash and the 
privet. It ranges from Maine and Canada to the Carolinas and 
westward into the trans-Mississippi region east of the great plains. 
(3) Ceratomia catalpae Boisduval, Plate IV, Fig. 7, $ . 
(The Catalpa Sphinx.) 
The larva feeds upon various species of catalpa, and has in 
recent years been charged with doing considerable damage to 
these trees by denuding them of their foliage. The insect ranges 
from New Jersey and southern Pennsylvania southward to 
Florida and westward through the Mississippi Valley, wherever 
its food-plant occurs. 
Genus ISOPARCE Rothschild & Jordan 
Tongue short and weak. Palpi small. Tibiae without spines. 
The first protarsal segment is short. Hind tibia armed with long 
spurs. Comb on mid tarsus wanting; pulvillus wanting. 
Paronychium without lobes. Veins 6 and 7 of the hind wing on 
a long stalk. 
(1) Isoparce cupressi Boisduval. 
(The Cypress Sphinx.) 
The insect is of an almost uniform 
brown color on the upper surface of 
the wings, and may be distinguished 
from other species by the two con¬ 
spicuous parallel dark markings on 
the limbal area of the fore wings. It 
is extremely rare in collections, only 
three or four specimens being as yet 
known. It has been reported from Georgia and Florida. 
Genus DICTYOSOMA Rothschild & Jordan 
This genus has been erected by Messrs. Rothschild & Jordan 
for the reception of the single species originally described by 
Strecker as Sphinx elsa.
