316 Catalogue of North American Sphinges. 
This insect appears to be the same as the one figured in Gué- 
rin’s Iconographie and in Griffith’s Cuvier, under the name of 
Aglaope Americana, Boisduval; but it is not an Aglaope, for it 
has a distinct, spirally-rolled tongue. 
Genus XVI. Guavcopis. F. 
The insects which, at present, I refer to this genus, belong to 
Zyzgena of the Entomologia Systematica of Fabricius ; whose 
Z. Glaucopis, if it was not actually the type, furnished the ge- 
nerical name which this author gave, in his last work, the Sys- 
tema Glossatorum, to this group of his former Zygene. Sev- 
eral of the insects, which Mr. Westwood, in his edition of Drury’s 
Illustrations, refers to the genus Callimorpha, without doubt be- 
long to the family Glaucopidide. Mr. Kirby has placed one spe- 
cies, after Lithosia, in a family which he names Ciéenuchide. 
ese insects seem to me much more nearly allied to the Sphin- 
ges adscite than to the Phalene of Liunzeus, with which also 
they agree in their diurnal flight, and in their transformations, so 
far as the latter are known. Although they do not appear to be 
strictly congenerical, I prefer to arrange them, for the preset, Un- 
der the genus Gilaucopis, in groups or subgenera, which, when 
the larvee and their transformations are better known, it may be 
proper to raise to the rank of independent genera. 
Subgenus Syntomeida. H. 
Antenne bipectinated, tapering at each end. Tongue moderate, spirally rolled. 
Palpi short, not extending beyond the clypeus, slightly curved and hairy at base, 
ed with short close seales; terminal joint somewhat acuminated. , 
near the tip of the wing. Body cylindrical, rounded and not tufted behind, and 
with a rounded tubercle on each side of the first abdominal segment. Spurs of the 
posterior tibiz four, small, and approximated. 
1. G. (S.) Ipomee. = Sesia Ipomea. Gmler, in letters. 
Fore-wings greenish black, with three yellowish white dots 
near the front margin and two others close together beyond the 
middle ; hind-wings violet-black, with a transparent colorless spot 
at base ; body tawny orange ; antenne and head black, the latter 
spotted with orange; a broad stripe on the shoulder-covers, a. 
transverse spot on the thorax behind, and the incisures of the ab- 
domen, black; legs violet-black; coxze beneath, and a spot on 
the thighs, orange-colored. Expands one inch and three quarters.
