Sphingidae 
(Chionanthus) and the jasmine. It is a common species in the 
southern States and Central America, but is only occasionally 
found in the northern States. I have not infrequently taken 
specimens in southern Indiana, and it is now and then 
captured in Pennsylvania and even in New England. 
Genus CHLiENOGRAMMA Smith 
This genus, which is very closely allied to the preceding, 
may be distinguished from it by the fact that the comb of long 
bristles of the mid tarsus, which is characteristic of Protoparce, 
is wanting or reduced to at most one or two bristles. Pulvillus 
and paronychium present. The eyes are smaller than in 
Protoparce, and are not lashed. There are two species in the 
genus, one South American, the other found in the eastern 
portion of the United States. 
(i) Chlaenogramma jasminearum Guerin, Plate VII, 
Fig. 6, $ . (The Ash Sphinx.) 
Syn. rotundata Rothschild. 
The larva of this hawkmoth feeds upon the various species 
of ash (Fraxinus). It is found in the middle Atlantic States 
and southward, and ranges as far west as the Mississippi. 
Genus DOLBA Walker 
Head small; eyes small and lashed. The antennae are 
fusiform with a short abrupt hook at the tip. The tibiae are not 
spinose. The mid tarsus has a comb. 
The genus, which contains but a single species, is differenti¬ 
ated from all those in which the eyes are lashed by the non- 
spinose tibiae. 
(i) Dolba hylaeus Drury, Plate VI, Fig. 4, ?. (The Papaw 
Sphinx.) 
This small, but neatly colored hawkmoth, may readily be 
distinguished by the figure given in our plate. Its larva, which 
is green, marked with lateral oblique red bands, commonly feeds 
upon the papaw, (Asimina triloba), and is generally abundant 
where that plant is common, as in the Valley of the Ohio. It 
is also said to feed upon Prinos. It ranges from Canada to the 
Gulf States and westward to Iowa and Missouri,
