Swainson, in 182 1 — 22 (Zool. Ilhis., ii., pi. 81 expl.), gave 

 convolvuli as "generic type" for Sphinx, but this was ultra vires, as 

 ligustri was already type of Sphinx. Curtis, in 1824 (expl. pi. iii), 

 specified elpenor as the type of Deilephila, but Hiibner had already, 

 in 1806 (anted, p. 347), specified elpenor as the type of Eumorpka, 

 so that Deilephila falls as a synonym of the latter. Stephens, 

 in 1828, divided flllus. Haust., i., p. in) the Sphingids into four 

 genera : 



1. Smerinthus, Latr. — Ocellatits, populi\ tiliae. 



2. Acherontia, Ochs. — Atropos. 



3. Sphinx, Auct. — Convolvuli, ligustri, pinastri. 



4. DEILEPHILA, Ochs. — Euphorbiae, galii, lineata, celerio, elpenor. 



This author united (loc. cit., pp. 132 — 136) Macroglossa, Ochs. 

 (with stellatarum as the type) and Sesia, Fab. (with fuciformis 

 and bombyliformis) as the Sesiidae, and referred the true "clearwings" 

 to the family sEgeriidae (loc. cit., pp. 136 ct sea.). Humphreys and 

 Westwood {Brit. Moths, i., p. 5) also place the Macroglossids in 

 Sesia, referring this genus to the Sfhi/tgidae.
