This seems to be as far as the first volume carried the classification, 

 at all events the article in question leaves that impression. On a 

 subse(juent page the systems of Schrank and Latr-eille are comj^ared 

 with the Fabrician scheme, principally in the Rhopalocera. 



The term Sesia is here used to express the idea fixed by Scopoli 

 for Macroglossa, while jEgeria is perfectly synonymous with Sesia, as 

 that term is restricted by Laspeyres and Latreille. 



Latreille, in 1809, used Scopoli's term Macroglossa, consideiing it, 

 however, not sufficiently distinct from Sphinx. In that year, too, he 

 divides the Lepidoptera into Diurna, Crepuscularia and Nocturna. 

 The Crepusculaires form two families : Sphln.gides, with ])rismatic 

 antennae, tufted at tip, and Zxjgwnides, with fusiform antenuie, not 

 tufted at tip. 



The Sphingides here include the genera Castnia (antennte clavate), 

 Smerinthus, Sphinx and Macroglossum. The Zt/gteaidce are here for 

 the first time excluded from the Sphiiigidxr, while they are retained 

 in the same group. 



Ochsenheinier, in the second volume of the " Schmetterlinge Eu- 

 ropa's" uses the term Sphinx in its widest sense, including Macro- 

 glossa and Svierinihus under the same term. Sesia is used in the 



TEANS. AMER. KNT. SOC. XV. (8) MAY, 1888.
