323 TAXONOMIC NOTES ON THE ORDER EMBIOPTBRA. XVI-XVII. By CoNSETT Davis, M.Sc, Lecturer in Biology, New England University College. (One hundred and eighteen Text-figures.) [Read 31st July, 1940.] XVI.-THE GENUS EMBIA LATREILLE. (Seventy-seven Text-figures.) Genus Embia Latreille 1829. Le Regne animal distribue d'apres son organisation, par M. le Baron Cuvier, Nouvelle Edition, revue et augmentee; p. 257 (foot-note). No specific name given. Genotype, Emhia savignyi "Westwood, 1837, Trans. Linn. Soc. London, 17, p. 372. Savigny (1809-1813) figured (PL ii, figs. 9-10) a species of the Order from Egypt, but no name was applied. Latreille (1825, p. 437) used the name Embie, as vernacular, and without description or reference to a previous description or figure; this use has therefore no taxonomic standing. Audouin (1827) used Embie with reference to Savigny's figure, but the name is still vernacular, and no standing can be attributed. In the same year Berthold made use of the form Embium, the first Latinized form; this, however, receives no consideration, being a nomen nudum. Latreille (1829, p. 257), under the name Embia, gives a short description, together with a note that the insect to which he refers was figured by Savigny. Although EmMa is here used alone, that is, as a uninomial, the genus dates from this record (cf. Opinions rendered by the International Commission on Zoological Nomenclature, Opinion 54, wherein certain genera of Raflnesque 1820, an author who was accustomed to use binary nomenclature, are confirmed as dating from 1820, though used by Raflnesque uninomially, without designation of species). In 1832, Griffith and Pidgeon (ex Gray manuscript) described a Neotropical Embiopteron, Olyntha trasiliensis, Olyntlia being designated a subgenus of EmMa Latr. The plate illustrating this species, drawn by Westwood, was issued as by Griffith and Pidgeon in 1831, with the title 'Embius? Brasiliensis G. R. Gray'; the query applying, not to the identity of the species (as only one specimen was then known; see "Westwood, 1837, p. 369), but apparently to doubt, at the time the plate w^as prepared, of the Latin ending to apply to the vernacular 'Embie' of Latreille (1825) and Audouin (1827). The generic name EmMus, dating from 1831 (but corx'ected by its authors to EmMa in 1832), is a homonym of EmMa Latreille 1829, by application of Opinion 115 of the International Commission. The name Olyntha is also invalidated by Olynthiis Hiibner 1818 (Coleoptera), a member of the same Class. The Neotropical series is not congeneric with the North African series (EmMa Latreille), and a new name is required to replace the invalidated Olyntlia. In 1837 "Westwood described Emdia savignyi, his description being based, not on any actual specimen, but on Savigny's figure, the original of which is the type of the species. As Savigny's figure lacks certain essential details (e.g. of the 00
