SPH1NGIDES. 347 



In 1805, Latreille gave {Hist. Nat. Crust. Ins., xiv., pp. 126 

 et sea.) a more extended view of the contents of the genera Sphinx, 

 Smerinthus and Sesia as follows : 



Sphinx. — Antennes en massue prism atique, terminees par un petit lilet 

 simple ; palpes fort larges ; une langue — Atropos, ligustri, convolvuli, elpenor, 

 porcellus, euphorbiae, gall Li, lineata, celerio, vespertilio, oenotherae, stellar urn (sic), 

 fuciforme, bombyliforme. 



Smerinthus. — Antennes prismatiques, pectinees ou en scie, crochues a leur 

 extremite ; langue tres-courte ou presque nulle — Tiliae, ocellata, populi. 



Sesia. — Antennes en fuseau et peu contournees, terminees par un petit 

 faisceau d'ecailles ; palpes presque coniques ; le second article plus fourni d'ecailles 

 ou de poils - Ap if or me, tipuliforme, culiciforme, chrysidiforme. 



The year 1806 saw the determination of the types of several genera. 



Hiibner, in his Tentameu, p. 1, gives the following types of stirpes 



relating to the groups under discussion : 



Phalanx ii : Sphinges. 



Tribus i : Papilionides : 



1 . Zygaenae — Zygaena filipendulae.* 



2. Chrysaores — Chrysaor statices.f 



3 . Glaucopes — Glaucopis phegea. 

 Tribus ii : Hymenopteroides : 



1. Sphecomorphae — Sphecomorpha incendaria. 



2. Sesiae — Sesia culiciformis. 



3 . Jhy rides — Thy r is pyralidiformis. 

 Tribus iii : Legitime : 



1. Bombyliae — Bombylia stellatarum \. 



2. Eumorphae — Eumorpha elpenor. 



3. Mandncae — Manduca atropos. 



4 . A morphae — A morpha populi. 



The selection of culiciformis as the type of Sesia, must be con- 

 sidered in the light of Cuvier's restriction of 1797. Otherwise 

 it would appear to have left the residuary and not congeneric 

 species of the " apiformis " group to represent Trochilium (a 

 view taken by Oken in 181 5), whilst atropos being selected 

 as the type of Manduca, elpenor as the type of Eumorpha, and 

 populi as the type of Amorpha, determined once for all the generic 

 appellations of these species. 



In 1807, Fabricius makes a personal advance, but goes back on 

 much of the work of his immediate predecessors, and practically 

 reaches Scopoli's position of 1777. He gives us (Illig. Mag., vi., pp. 287 

 — 288) the following groupings, which do not much influence the 

 synonymy : 



Laothoe §. — Taster zwei, rauh, sehr stumpf, zweigliedrig. Rollzunge sehr 

 kurz, hautig, fast undeutlich. Fuhler fadenformig ; Glieder unten schuppig. 

 — Sphinx ocellata, quercus, tiliae, populi. 21 Art. 



Sphinx. — Taster dikk, rauh, sehr stumpf, zweigliedrig. Fuhler fadenformig, 

 unten schuppig. (1) Gezahnte Flugel. — Sphinx ello, tetrio. (2) Gauzraudige 

 Fliigel. — Sphinx nerii, atropos, euphorbiae, ligustri. 74 Art. 



Sesia || .—Taster zwei, kurz, dikk, rauh, sehr stumpf, zweigliedrig. Fuhler 

 nach aussen dikker mit einem kleinen Haken an der Spitze. (1) Flugel ausgenagt. 

 — Sphinx oenotherae. (2) Flugel ganzrandig. — Sphinx stellatarum, fuciformis. 

 18 Art. 



* Cotypical with Scopoli's Anthrocera, fixed in 1777. 



t Cotypical with Adscita, Retzius, 1783. 



X Cotypical with Scopoli's Macroglossum, fixed in 1777; and Fabricius' Sesia, 

 fixed in 1797. 



\ Grote, in 1874, pronounced [Bull. Buff. Soc, i., p. 24) populi to be the 

 type of Laothoe, which may be considered as making it synonymous with Amorpha. 

 We have hitherto been inclined, however, to look upon quercus as the residuary type 

 of the genus Laothoe. 



|| Already restricted (1797) by Cuvier with stellatarum as type.
