In 1835, Duponchel published [Hist. Nat. Left., supp. ii., pp. 

 155 et sea.) the Sphingid section of his "Catalogue Methodique des 

 Lepidopteres d'Europe." Tabulated, his results work out as follows : 



1. Sphinx, L. — Ligustri, L., and var. spireae, Hb., convolvuli, L., pinastri, L. 



2. Deilephila, Ochs. — Nicaea, de Prun., euphorbiae, L., galii, F., dahlii, Tr., 



epilobii, Bdv., esulae, Bdv., tithyniali, Bdv., zygophylli, Ochs.,

In 1836, Duncan created {Brit. Mofhs, p. 154) the heterotypical 

 genus Metopsilus for »*r» (type of Daphnis\, Hb.), celerio (type of 

 Hippotion, Hb.), elpenor (type of Eumorpha, Hb.), and porcellus (type 

 of Theretra, Hb., and Choerocatnpa, Dup.), whilst Westwood, in 1840, 

 gives (Genet: Synops., pp. 88 — 89) the following summary of the 

 Sphingid genera : 



Family 1 : Sphingid^e, Leach. 



Smerinthus, Latr. (Laothoe, Fb.). — 3 spp. S^M. ocellata, L. — Wings 

 angulated ; spiral tongue short. 



ACHERONT1A, Ochs. (Brachyglossa, Bdv.).-^i sp. -S^//. atropos, L. — Wings 

 entire, acute, spiral tongue short. 



Sphinx, Linn. (Ewnorphae, Hb.). — 6 spp. Sph. ligustri, L. — Wings entire, 

 acute, spiral tongue very long ; antennae not clavate ; labial palpi robust. 



Deilephila, Ochs. (Spectrum, p., Scop.). — 3 spp. Sph. euphorbiae, L. — Wings 

 entire, not subfalcate ; spiral tongue long ; labial palpi robust ; antenna? clavate; neck 

 of larva not retractile. 



Daphnis, Hb. (Sphinx, L.). — 1 sp. Sph. nerii, L. — Wings entire, acute, 

 posterior slightly lobed ; spiral tongue long ; antennas and labial palpi slender ; cater- 

 pillar with the neck retractile. 



Metopsilus, Duncan (Eumorphae, Hb.).— 3 spp. Sph. elpenor, L. — Forewings 

 subfalcate ; antennas obscurely clavate ; spiral tongue long ; neck of caterpillar 

 retractile. 



Macroglossa, Ochs. (Sesia, p., Fb.).— 1 sp. Sph. stellatarum, L. — Wings 

 squamose; apex of abdomen strongly tufted. 



SESIA, Fb. (Macroglossa, p., Ochs.).— 2 spp. Sph. fusifor/nis, L. — Wings 

 partially hyaline ; abdomen tufted at the extremity. 



Westwood's determinations are correct for Smerinthus, Sphinx, 

 Daphnis and Macroglossum, but the latter under existing rules 

 falls before Sesia, Fab. By fixing elpenor as the type of 

 Metopsilus, the latter becomes a synonym of EittnotpJia, Hb., 

 whilst his Sesia is, of course, synonymous with Honoris, Dalm. We 

 have already noted (anted, pp. 348, 352) that Curtis' action in fixing 

 elpenor as the type of Deilephila makes the latter genus synonymous 



* In D'Orbigny's Diet. Univ. Hist. Nat., iii., p. 613 (1843), Duponchel fixed 

 on porcellus as the type of this genus. 



t Curtis, Brit. Ent., xiv., fol. 626 (January, 1 S 3 7 ) , figured nerii, and declared 

 it to be the type of the genus Daphnis.
