AND THEIR TRANSFORMATIONS. H; 



Like several of the allied species, this insect is duuble-brooded, appearing in Juno and August. Fabricius, by 

 whom the species was first described, gave it as a native of Fjii/land, from the drawings of Mr. Jones. It appears, 

 however, to be e.xclusively an inhabitant of Scotland, and was, until lately, supposed to be only found on Arthur's 

 Seat, Edinburgh, being of such rarity, tliat scarcely a singli; caliinet jiossessed a specimen, the owners endeavouring, 

 according to the bad taste of the day, to sup]dy its place with a drawing of the insect stuck in their cabinets. 

 More recently, however, it has occurred in considerable plenty, not only in the locality above mentioned, but 

 also on Salisbury Craigs, King's Park, and near Duddingston Loch, Pentland Hills, near Qucensferry and 

 Rosslyn Castle, Jardine Hall, Dumfriesshire, and Flisk, in Fifeshire. The other localities mentioned by Mr. 

 Stephens appear to belong to Salraacis, except the last, " Dartmoor, 23 August, 1823, Dr. Leacli," which is 

 probably erroneous. 



In addition to what has been already observed under P. Agestis, relative to tlie specific rank of this and tlie 

 two preceding species, it must bo stated, that althougli Agestis is very abundant on tlie Continent, the Continental 

 Entomologists have never met with a single specimen of Artaxerxes, their cabinets being entirely furnished with 

 Scotch specimens. 



PoLYOMMATUS TiTDS (Ilcsperia T., Fabrieius ; Turton; Donovan in Recs'' Encyel. art. Pai)ilio, Jermvn ; 

 Stephens,) was described by the first-named author as a native of England, on tiie autliority of .Air. Drurv 

 and Mr. Jones's collection of drawings of Lepidoptera *. Mr. Haworth, however, who was personally well 

 acquainted with the latter gentleman, states that the inforuiatlon given to Fabrieius was incorrect, the insect not 

 being a native of this country. The following is a translation of his character : — Stature quite like Artaxerxes, 

 &c. ; all the wings above, brown, unspotted ; beneath, also brown ; the anterior, with a posterior, or submarginal, 

 row of short white and black lines, and the posterior, with a central short line, and a row of black dots, edged 

 with white ; near the margin is a row of red sjjots, each marked with a black dot. 



FAMILY V. 

 HESPERIIU/E. 



This family, which is the sixth in the arrangement of the diurnal Lepidoptera in general, was well indicated 

 by Linnaeus, nnder the title of Papiliones Plebeii Urbicoli, and is composed of a very distinct tribe of butterflies, 

 constituting, indeed, a primary division amongst them, which Boisduval has termed Involuti, from tlie circumstance 

 of the caterpillars inclosing themselves in a curled-up leaf; and thus, as well as in several other important 



characters, approaching the moths. 



The six feet arc of uniform size in both sexes ; the hind tibi;e have a pair of spurs at the apex, and generally 

 another pair near the middle of the limb, a character found in none of the preceding butterflies ; the hind wings arc 

 generally horizontal during repose, and in some species all the wings are placed in this manner (Tamyris Zeieucus,
