The handsome and remarkable variety of Papilio Aglaia 

 represented in the plate, is well deserving the first place in a 

 new volume, especially as it is a great rarity and does not 

 ajipear to be figured in any other work. Two specimens (one 

 of which I purchased) were taken by Mr. John Seaman in the 

 parish of Nacton, near Ipswich, the 7th of July 1827. For 

 an intermediate variet}' which was captured at Dover, I am 

 indebted to Mr. W. Christy: it is singular that these spe- 

 cimens vary from the type no less in form than in colour, 

 which is not the case I believe with A. Carole tta. The cater- 

 pillar and chrysalis are copied from H'ubner. 



The genus Argynnis is at oncis distinguished from Melitasa 

 by its very ample wings, broad head and large eyes, and con- 

 tains the following British species. 



1. A. Paphia Linn. — Don. Brit. Ins. v. I.pl. 247, male. 

 The end of May and beginning of July, borders of woods 



and in meadows, on brambles and thistles. — The caterpillar 

 feeds on the dog's violet, raspberry and nettle. 



2. A. Aglaia Linn. — Don. 9. 302, male — var. (3. Charlotta 



So-iSoerhy Brit. Mis. tab. 11. — Caroletta Jerm. — var.l 



Curtis Brit. But. pi. 290. 

 July and August, woods, meadows, heaths and downs, upon 

 brambles and thistles. The A. Charlotta was first taken the 

 beginning of July in Bedfordshire, by Dr. Abbott. — The ca- 

 terpillar feeds on the dog's violet. 



3. A. Adippe Linn. ?—Esper. — Do7i. 13. 448. 



End of June and July. Heaths and borders of woods. — 

 The caterpillar feeds on the sweet violet and the heart's-ease. 



4. A. Niobe Linn. — Godart v. 2. pi. l.f. 3, 4, 5. 



Godart thinks this is the P. Adippe of Linnseus ; and the 

 same opinion might lead Stewart to record it as a British in- 

 sect. Dr. Abbott's English collection contained a specimen, 

 which Mr. Dale now possesses; and as it is found in Sweden 

 and the South of France, there is nothing unreasonable in 

 believing that it may occasionally make its appearance in this 

 Island. — The caterpillar feeds on the violet and plantain. 



5. A. Lathonia Linn. — Doti. 3. 73. — Scpp. v. 2. pL 2. 

 May: Gamlingay Wood, Cambridgeshire. Aug.: Halver- 



gate, Norfolk ; Battersea-fields ; Castle Meadow and Shak- 

 speare Cliff, Dover. Sept.: Birchwood, Kent; Hertford and 

 Colchester. — This papilio is fond of the dandelion ; but the 

 caterpillar feeds on heart's-ease, sainfoin and borage. In En- 

 gland it is a rare insect, and is sometimes not seen for many 

 successive seasons.
