316 Catalogue of North American Sphinges. 



This insect appears to be the same as the one figured in Gne- 

 rin's Iconographie and in Griffith's Cuvier, under the name of 

 Aglaope America7ia, Boisduval ; but it is not an Aglaope, for it 

 has a distinct, spirally-rolled tongue. 



Genus XVI. Glaucopis. F. 

 The insects which, at present, I refer to this genus, belong to 

 Zygaiia of the Entomologia Systematica of Fabric] us ; 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 Glossaiorum, to this group of his former Zyganoi. Sev- 

 eral of the insects, which Mr. Westwood, in his edition of Drury's 

 Illustrations, refers to the geims Callimorpha, without doubt be- 

 long to the family Glaucopididce. Mr. Kirby has placed one spe- 

 cies, after Lithosia, in a family which he names Ctennchidoi. 

 These insects seem to me much more nearly allied to the Sphin- 

 ges adscita tlian to the PhahmtB of Linnajus, 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 present, un- 

 der the genus Glaucopis, in groups or subgenera, which, when 

 the larvas and their transformations are better known, it may be 

 proper to raise to the rank of independent genera. 



Subgenus Sijntomtida. 11. 

 Antennae hipeclinated, tapering ut each end. Tongue moderate, spirally rolled. 

 Palpi short, not extending beyond the clypeus, slightly curved and hairy at base, 

 covered with short close scales ; terminal joint somewhat aouminated. Wings 

 elongated, hind-pair small, with the discoidal cell closed behind by an acute-an- 

 gled nervurc, the anterior branch of which crosses the subcostal nervure and ends 

 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 tibia four, small, and approximated. 



1. G. (S.) Ipomxcc. = Sesia Ipomace. (Emler, 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 ; antennae and head black, the latter 

 spotted with orange ; a broad stripe on the shoulder-covers, a 

 transverse spot on the thorax behind, and the incisiues of the ab- 

 domen, black ; legs violet-black ; coxa; beneath, and a spot on
