224 BEUTENMULLER, MONOGRAPH OF THE SESIID^E. 



pointues. Quelques unes des ailes souvent vitrees abdomen presque cylindrique, 

 garni dune espece de brosse a l'extremite." No particular species is mentioned, 

 but the description may very well be applied to the Sesiidse. 



In 1798 (51) Cuvier made Sphinx stellatarum the type of the genus Sesia, 

 but this restriction renders Sesia synonymous with Macroglossum of Scopoli. 



Laspeyres in 1801 (52) published a monograph of the European Sesiidse, 

 using the name Sesia in a restricted sense. He excludes all the species not 

 properly belonging to this family. 



During the same year Lamarck (53) restricted the genus Sesia to Sphinx 

 (— Hemaris) fuciformis, and Schrank (54) used the name Sesia in the same 

 sense as Laspeyres, but included under it Thyris fenestrina. 



In 1805 (62) Latreille adopted the name Sesia in the same sense as Laspeyres, 

 or used the name to indicate the species intended to be included in this genus as 

 described by him in 1796. 



Hiibner in 1806 (65) restricted the name Sesia to 5. culiciformis of Clerck. 

 This is apparently the first restriction, and this species should be considered as 

 the type of the genus, unless we can find another author mentioning a type 

 before this. 



Fabricius in 1807 (66) proposed the name Algeria for apiformis, ichneumoni- 

 f or mis, and vespiformis, and Sesia for Sphinx oenotherce, S. stellatarum, and ,S. 

 fuciformis. The name Algeria as here used is synonymous with Sesia of Las- 

 peyres (1801), and Sesia stellatarum with Macroglossum of Scopoli (1777), while 

 Oenothera and fucifownis must be referred back to the Sphingidae. If we reject 

 the term Trochilium, as proposed, Algeria should be used for apiformis. In 

 1809, Latreille (72) again uses the name Sesia in the same way as in 1805. 



In 1816 (yy) Hiibner proposed an entirely new classification of the Lepi- 

 doptera, and erected for the Sesiidae the following genera : Sphecia for apiformis 

 and bembeciformis ; Melittia for bombiliformis Cramer. Bembecia is used for 

 hylcsiformis, empiformis, tenthrediniformis, scoliczformis, tipuliformis, and a num- 

 ber of other congeneric species. Synanthedon and Conopia are used for species 

 referable to his genus Bembecia and which are all congeneric with the name Sesia 

 as used by Laspeyres ; hylceiformis is the only species not belonging in the 

 series, and Sphecia is equivalent to Algeria Fabricius (1807), as used by New- 

 man in 1832. 



Leach in 18 16 (75) uses the name Algeria for the species referred to it by 

 Fabricius in 1807. 



In 1825 Olivier (92) restricted the name Sesia to crabronifoi'mis (= api- 

 formis), but this restriction comes in conflict with that of Hiibner (1806), and 

 consequently renders it untenable. 



Stephens in 1828 (102) restricted Scopoli's name Trochilium to apiformis, 

 and gave a good diagnosis of the genus, which, however, does not agree with 

 that of Scopoli, and the restriction comes in conflict with y^geria of Fabricius
