Tliis species measures 1 • inch in the expanse of the fore wing.s, which are varied with brown and ashy, and 

 marked with a somewhat silvery mark, which extends from the base nearly to the middle of the wincr resemblina 

 a letter V as written rather than printed ; before and within the letter, the wings are ashy towards the costa ; 

 the two terminal strigaj are slender and jiale, but distinct ; and the stigmata have a very pale edging. Very rare ; 

 taken in Essex by Drury, and near Hull by Mr. Hewitson. The caterpillar is green, with a white lateral line 

 edged above with brown, and with curved brown dorsal stripes.

 pi. 54, fig. 52. 



This species has the wings finely varied with purple, rich brown, and golden yellow ; a broad oblique central 



brown band, on which .are i>Iaced two white or pale buff spots ; behind which is a golden patch extending to the 



anal margin, and divided by the slender pale striga following the stigmata, whicli are not very distinct ; the 



subapical striga is much anguhated, and preceded by an irregular brown bar. This species is a native of Italy 



and the South of France ; and the only authority we have for its having occurred in this country, is a specimen 



found by the late Sir. Standish, in an old frame containing moths arranged ornamentally. 



SPECIES !).— PLUSIA BILOBA, Stephens. 

 Synonvmf.. — Plusia biloha, Stephens' Illustrations, Hanst. 3, 104. 

 Expansion of the fore wings 1 inch and 5 lines. " Fuscous tinged with purplish ; anterior wings of a rich 

 purplish brown, with darker undtilated strigre, nearly as in PL Gamma ; at the base are several ficxuous golden 

 striga^, and towards the costa, near the apex, is a mark of a similar hue resembling a reversed Q ; in the centre 

 of the winof is a laro-e brilliant .silvery patch, producing two lobes towards the costa ; the rest of the wing and 

 the posterior wings resemble those of PI. Gamma," Steph. op. cit. A single specimen, now in jMr. Stephens's 

 collection (from that of Mr. Swainson), of which the locality is unknown, is the only authority for this species, 

 of which no figure has been yet published. Jlr. H. Doubleday considers it to be North American. 



SPECIES 10.— PLUSIA AURIFERA. Plate LIL, Fig. .5. 

 SvNONVME.— A'oc/uu atirifcra, Iliibner ; Tieitsclikc ; Duponchel ; Stephens ; Wood, lud. Eut. pi. 10, fig. 403. 

 This species measures IV inch in the expanse of the fore wings, which are of a pale brown colour, with the 

 stigmata and two basal strigie slightly indicated, with a greenish gold patch in the middle of the wing somewhat 

 lozenge-shaped, and which is dilated beyond the middle into a broad bar extending from the costa almost to the 

 anal angle, followed by a slender yellowish subapical striga. Very rare, if indeed the true PI. Aurifera be really 

 indigenous ; as the specimen in the British Museum, taken near Dover by the Rev. G. Lyon, has been 

 considered as a singular variety of PI. chrysitis, PI. aurifera being described as a native of Spain, Portugal, the 

 South of France, Tenerifie. &c. Another specimen, supposed to have been taken near London, was formerly in 



Mr. Ingpen's collection.
