H^MEROSIA. 



283 



a black dot, which represents the reniform stigma ; hind-wings pale grey. Expands about 

 half an inch. It inhabits South Europe and Western Asia in June, and specimens were taken 

 by Dr. Rattcrsby at Torquay in 1859, in company with Ostrina. Some doubt having been 

 expressed as to the British specimens being really Parva, I may add that having had an 

 opportunity of comparing Dr. Battersby's original specimens with Continental specimens and 

 descriptions, I have come to the conclusion that they really belong to that species. The larva 

 lives in the seed-capsules of Inula inontana, and becomes a pupa there. 



15. T. Paula (Hubn.).— Fore-wings olive-grey, whitish at the base, with a dark oblique 

 band in the middle, and a whitish transverse stripe in the marginal area, projecting in an obtuse 

 angle ; hind-wings pale grey, edged with darker. Size of Ostrina. Common in the southern 

 half of Central Europe from June to August. The larva is pale green, with a dark double 

 Ime on the back. It feeds on Gnapbalium arenariiini in June. 



16. T. Viridula (Guen.).— Fore-wings yellowish olive-green, with an oblique brownish stripe 

 before the middle ; hind margin grey, with rusty-brown spots at the tip and on the inner 

 margin, between which projects a tooth of the white ground-colour ; hind-wings whitish at the 

 base. Size of Ostrina. The variety Elychrysi, from Corsica, Sardinia, and Sicily, may be 

 distinguished by its dark greyish-green colour ; the true Viridula is common in South Europe 

 and Western Asia. 



17. T. Candidana (Fabr.).— Fore-wings white, with an oblique central band and the hind 

 margin rusty-red ; the latter is varied with white towards the extremity, and the intermediate 

 white band projects a tooth outwards in the middle ; hind-wings grey, whitish at the base. 

 Expands nearly three-quarters of an inch. Common in South Europe and Armenia in June and 

 July. The variety Impura (Staud.), from the south-west of France, is smaller and darker, and 

 varied with brownish instead of rust-colour. {T. HimmigJwffeni, Mill., has yellow, rather pointed 

 fore-wings ; the subterminal band is blackish, broad in the centre, and narrower at the extremities ; 

 the costa and a broad transverse central band are satiny white ; fringes dark grey ; hind-wings 

 white, with yellow fringes. T. Barcinonensis, Mill., has moderately pointed fore-wings; the costa 

 IS very little arched, and the hind margin quite straight, pale straw-colour, with a slightly 

 indicated brown subterminal band, and a very small black central dot ; between these is a 

 small oblong blackish spot. Hind-wings very pale straw-colour, almost white. Both these 

 species are about the size of Ostrina, and are found at Barcelona in June.) 



18. r. Pura (Hiibn.).— Fore-wings shining white, slightly washed with yellowish, with a 

 central curved band, and the hind margin yellowish-red. Stigmata replaced by two small black 

 dots ; fringes very long, and tinged with reddish at the extremities, as are also the white 

 hind-wings. Expands about three-quarters of an inch. Common in summer in South France 

 and Spain. 



GENUS VII. — H^MEROSIA (BOISD.). 

 Antenn^E pectinated in both sexes ; wings shaped nearly as in Trothisa, but with an 

 accessory cellule on the fore-wings, which is wanting in that genus. The only species, H. 

 Refiahs (Hiibn.), has flesh-coloured wings, the fore-wings with a white reniform stigma, placed 

 brownish elbowed line, which is bordered with whitish on the outside, and consists of slender 

 lunules ; the inner line is often indistinct ; the hind margin and fringes are suffused with brown, 

 and the hind-wings are without markings. Expands about i inch. It inhabits South France 

 in spring and autumn, and the larva feeds on the flowers of different species of Lactuca and 

 Chondrilla.
