138 , ADDENDA AND CORRIGENDA. 
In addition to the species described in the preceding pages, the following have also been incautiously introduced into the lists of 
British species, but upon such slight authority that it has not been deemed necessary to figure them in this work. 
Parnassius Mnemosyne, Latreille (Papilio Mn. Linneus). Itis smaller than Apollo, from which it is at once distinguished 
by wanting the ocelli. The veins are slender and blackish, the fore wings with two black spots in the discoidal cell. 
It inhabits the Alps, Pyrenees, Switzerland, Sicily, Sweden, Hungary, and Russia. It may therefore possibly still 
be found in England. It was introduced by Turton and Jermyn, and is figured in Wood’s Ind. Entomol. pl. 53. f. 4, 
amongst the doubtful British species. 
Prerts Frronia (Pontia F. Stephens, Il. Haust, 1, 149; Ernst, Papillons d’Europe, vi. p. 209). ‘‘ Wings above white, the 
anterior with a single row of triangular brown spots touching the hinder margin, and terminating in a point on each 
nervure internally ; beneath immaculate, the anterior white, with a yellowish tint on the outer angle; the posterior 
entirely of the latter colour irrorated with dusky.” Ernst, by whom alone this species appears to have been noticed 
and figured amongst Continental authors, says of it that it was “prise en Angleterre.” No other authority exists for 
its being an indigenous species; and Mr. Stephens suggests that it may be a native of New England, in America. 
Metitaa Tuaros (Papilio Dan. Fest. Tharos, Drury, App. v. 2; Cramer, pl. 169, fig. e. r.; Argynnis Tharossa, Enc. Méth. 
9 289; Melitea Tharos, Westw. in Drury, 2nd Edit. 1, p. 39). The wings are black-brown, with many orange 
marks, some of which form an irregular bar beyond the middle of the fore wings, the tips and margins being dark. 
There is also a row of black round spots in orange spaces beyond the middle of the hind wings. This is a common 
? 
North American insect ; but Cramer, in figuring it, stated it was “recu d Angleterre ;” whence it has been inferred 
that it was regarded by him as an English species. 
Limenitis Poputt, Fabr. (Papilio P. Linn. Stewart ; Wood, Ind. Ent. t. 53, fig. 10). The wings above brown, fasciated 
and spotted with white; beneath, luteous, fasciated with white, and ornamented with blue spots. This tine species, 
which is nearly three inches in expanse, appears to have been introduced in the English lists in consequence of Lin- 
neus having erroneously referred to Ray’s description of Camilla, amongst his synonyms of Populi. 
Livenitis Sterna, (Papilio 8. Linn. Stewart; Wood, Ind. Ent. t. 53, fig. 11, L. Camilla Fabricius), is closely allied to L. 
Camilla, with which it has been confounded by Fabricius. Stewart, who followed the nomenclature of the latter 
author, accordingly gave Sibilla as a native species. The true Sibilla is nearly two inches and a half in expanse ; the 
wings above, dark brown, with a white fascia, without any red spot at the anal angle; beneath, orange-tawny, spotted 
as above. No authentic instance is recorded of its capture in this country. 
Potyommatus Trrus (Hesperia Titus, Fabricius, Ent. Syst. 3, a. p. 297; Turton: Pol. Titus, Jermyn, Stephens). Habit of 
Argus and Artaxerxes. All the wings above brown, unspotted. Beneath also brown, the anterior with a hinder row 
of white and black lines, the posterior with a short central line, and a row of black spots ocellated with white. Near 
the margin are a row of red spots, each marked with a black dot. “Habitat in Anglia. Dom. Drury. Jones, fig. 
pict. 6, t. 44, t. 2.” It appears that Fabricius derived his knowledge of this species from the same source, whence he 
also described Artaxerxes, namely, Jones’s Collection of Drawings. Beyond this we have no information respecting 
the species.
