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 

 subsequent page the systems of Schrank and Latreille are compared 

 with the Fabrician scheme, principally in the RhopaJocera. 



The term i^esia is here used to express the idea fixed by Sco[)o!i 

 for Maerofflossa, while JEgeria is perfectly synonymous with Sesia, as 

 that term is restricted by Laspeyres and Latreille. 



Latreille, in 1809, used Scopoli's term Macroglomi, considering it, 

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

 divides the Lepidoptera into Diurna, Crepuscularia and Xocturna. 

 The Crepusculaires form two families : Sph'nigldes, with j)rismatic 

 antenme, tufted at i\\^, and Zygcenides, with fusiform antenna-, not 

 tufted at tip. 



The Sphingides here include the genera Caxfiiia (antenme clavate), 

 Smerintlnis, Sphinx and Macroglossum. The Zygcenidxc are here foi- 

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

 in the same group. 



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

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

 glossa and Smerlnthtis under the same term, Sesia is used in the 



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