instead of rolling the leaf up as practiised by the genuine Tor- 

 tricidae. 



Although there are only 3 British species, they vary con- 

 siderably in their form, &c., and by the following divisions it 

 will be seen that if the last be established as a genus, the other 

 two have equal claims to the same distinction. It is remark- 

 able that all English writers, until the error was corrected in 

 my Guide, had misnamed the two first species. The mistake 

 originated in Fabricius; but it is singular, after the observation 

 made by Donovan, and the clear description of Linnaeus in his 

 Faun. Suec, that Haworth and other writers should not have 

 seen their error. 



* Antenna2 tapering to the base and apex. Palpi slightly 

 hairy. 



1. H. prasina Linn. — Fragana Fab. — Don. 8. 281. — Sylvana 



Fab. 



White, head and thorax green, lateral lobes margined with white : 

 superior wings pea-green, with 3 oblique white lines, that reach- 

 ing the apex curved ; cilia, costa, outside of legs and antennre 

 bright red in the male : expansion of wings 18 lines. 

 From the end of May to end of July, paths in woods round 

 London, also in Durham, Bedford, Kent, and Devon. Pen- 

 wood, Hants; near Newbury; New Forest and Glanville's 

 Wootton ; Mr. Dale. 

 Larva in Aug. and Sept. on Beech, Birch, Alder, and Oak. 



** Antennae setaceous. Palpi clothed with short scales. 



2. Quercana Hiib. — Curt. Brit. Ent. pi. 575. — prasinana Fab. 



White ; clypeus, outside of palpi, antennae and anterior legs bright 

 red, crown of head, thorax (except the anterior margin), and su- 

 perior wings of a fine uniform grass green, 2 fine ohlique white 

 lines across the centre, the costa and cilia white also. Seldom so 

 large as the figure. 

 From middle of June to middle of July, Coomb, Birch, and 

 Darent Woods; once found in Durham. Glanville's Wootton 

 and Middle Marsh ; Mr. Dale. 



Larva on Oaks and Alders, in May and September. 



*** Palpi rather stouter, 2nd joint more scaly. 



3. Clorana Li7in. — Hiib. 25. 160. 



White; thorax, excepting the collar, green; superior wings of 



the same colour, with a broad space on the costa at the base and 



the cilia white : expansion 1 1 lines. 



Beginning of June, Willow-beds, near Norwich and Parley 



Heath, Hants; 19th July, Whittlesea Mere, J. C. Battersea 



Fields, and the banks of the Thames at Woolwicli, Plumstead

From M. Duponchel we learn that the larva is found in 

 France, the end of July and beginning of August, on various 

 Sallows, feeding amongst the leaves at the extremity of a twig 

 or branch, which it unites with threads. 



Obs. The larva, pupa, and oak-leaves are copied from 

 Hlibner ; the moth and cocoon are from nature.
