_M. alis supra fuscis; anticis fasciis duabus obsoletis, puncto nigrante terminali, posticis in medio, tribus maculisque lateralibus abdominis aurantiacis._ Wings brown; anterior with two darker obscure bands, and a terminal blackish dot; middle of the posterior wings, and three lateral spots on the body, orange. * * * * * This genus was instituted by Scopoli many years ago, and differs principally from _Sesia_ by having opaque wings, and from _Thyreus_ by the very great difference in the construction of their antennae. Many exotic species are known, but only one is found in Europe (_Sphinx stellatarum_ of Linn.), which likewise inhabits our own country, and to which this our insect is very nearly allied. Though by no means uncommon in collections, I cannot find this species either figured or described, nor indeed am acquainted with its locality. The under figure is of the male; the upper of the female; which differs only in the wings being rather broader, and in having one segment in the body less than in the other sex. * * * * * Pl. 65 [Illustration] CONUS Augur. _Girdled Cone._ * * * * * GENERIC CHARACTER. _Testa univalvis, turbinata, s. inverse conica, convoluta; apertura longitudinalis, angustata, edentata; basi effusa; spira brevissima._ Typus Genericus _Conus marmoratus_, &c. Linn. Shell univalve, turbinated, inversely conic, convolute; aperture longitudinal, narrow, not toothed; base effuse; spire very short. Generic Type _Conus marmoratus_, &c. * * * * * SPECIFIC CHARACTER. _C. testa glabra, fulvo-albida, fasciis latis nigro-castaneis, lineisque transversis punctatis; spira obtusa, convexa, striata, depressa._ Shell smooth, fulvous-white, with broad dark chesnut bands and transverse lines of dots; spire obtuse, convex, striated, depressed. C. augur. _Lamarck Annal. Mus._ xv. 277. _Encycl. Meth._ 333. 6. Conus magus. _Gmelin_ 3392. 57. _Martini_ ii. 58. 641. * * * * * The Girdled Cone is conspicuous among the beautiful shells of this extensive family, by the broad and rich chesnut bands, which are either two or three in number, and more or less broken into spots; in high-coloured shells the minute lines of dots between them are also of the same colour. It is not a common species, and inhabits the Asiatic ocean. This is the _Conus Magus_ of Gmelin and Martini, and of our sale catalogues: this error has originated from Gmelin having described two distinct shells, _C. Augur_ and _C. Magus_, under the latter name. I have not referred to Lister's figure 755. 7, being doubtful of its affinity; and those of Martini and Bruguieres are very bad. * * * * * Pl. 66 [Illustration] MITRA lugubris. _White-banded Mitre._ * * * * *
