EVERES ARGIADES.

Pyrenees — Guethary (Sheldon), Biarritz (HinchlirT) ; Charente-Infe- 

 rieure — St. Mariens, similar to the vernal form from Rennes 

 (Oberthur) ; Ille-et-Vilaine — Forest of Rennes, Monterfil, Montfort 

 (Oberthiir) ; Indre — Forest of Amboise (Lelievre) ; Var — near Cannes 

 (Chapman), are to be referred here ; whilst other less certain records 

 are : Allier (Peyerimhoff) ; Doubs (Bruand) ; Dordogne (Tarel) ; Loire- 

 Inferieure — Nozay (Doherman-Rey) ; Cher, Indre, Puy-de-D6me 

 (Sand). In Switzerland it is recorded from Vaud — Crassier, at the 

 foot of the Jura, in May (de Loriol), whilst in the Brit. Mus. Coll. are 

 several examples from the Zurich district (Frey). This form is the 

 amyntas of Borkhausen (and, as Bergstrasser himself notes (antea p. 61), 

 the Papilio amyntas of Schiffermuller is his insect, the latter name being 

 dropped because the earlier Papilio amyntas of Poda and Scopoli has been 

 referred to Coenonympha arcania). Borkhausen separated it as an aberra- 

 tion of the larger form (uniting them, however, specifically under the 

 name tiresias) on the following grounds : " (1) Half the size. (2) Flies in 

 spring when tiresias does not occur. (3) The female always mixed 

 with blue above without orange spots at the anal angle. (4) The 

 antennal club not white apically, but quite black, obtuse, and some- 

 what indented." Illiger, in 1801 (Schmett. Wien., 2nd ed., p. 274), 

 suspected these were merely small examples of the larger species occurr- 

 ing throughout the summer. Ochsenheimer mentions it (Die Schmett., 

 i., pt. 2, p. 62) as flying in the Leipzig district in April and May, 

 two months earlier than amyntas, and adds that, in Schiffermuller 's 

 collection, it stood as a variety of amyntas. We have already noted the 

 references in the German and Austro-Hungarian literature to this 

 name (antea p. 62), where it is clear that the authors are using the 

 name for the smaller first-, as compared with the larger second-, brood. 

 We have also already suggested that some of the references to polysperchon 

 in the French entomological literature possibly refer to the same form, 

 but others (possibly many) refer to Everes alcetas, to which species 

 some authors certainly misapplied the name. In view of this general 

 consensus of opinion, and of the fact that Bergstrasser's description 

 given above is obviously not altogether in harmony with his figure of 

 the 2 > it will perhaps be best to retain his name polysperchon for the 

 small spring brood and to name the form as figured, but not as described, 

 by him — 



/3. ab. bergstrasseri, n. ab. Polijsperchon, Bergstr., " Nomen.," ii., pi. xliv., fig. 

 5, ? (1779); H.-Sch.,"Sys.Bearb.,"i., p. 129 (1843).— This is a very small ? form, 

 of the same tint, and almost as blue, as the S polysperchon figured by Bergstrasser 

 (Nom., ii., pi. xliv., fig. 3), with broad, rather broken, dark, marginal band to the 

 forewings shading off internally, almost to the middle of the wing ; the submarginal 

 band of the hindwings, broken on the margin by a series of pale bluish crescents, 

 outlining the usual outermarginal series of dots, which are thus rendered somewhat 

 conspicuous. 



This 2 aberration appears only to occur with the spring form, but 

 is rare, very few of the 2 s of the spring race being as extreme as 

 Bergstrasser's figure. 



y. ab. jodina, Aign.-Abafi, "Ann. Mus. Nat. Hung.," iv., p. 515 (1906).— Tn 

 the ? gen. vern. polysperchon, the forewings at the base and on the discal area, 

 nearly to the outer margin, as well as a weak marginal stripe, are tinged with blue ; 

 the hindwings, on the contrary, only at the base, and towards the margin ; the 

 marginal dots very weak. But, in an example, taken May 14th, 1891, at Eperjes, 

 by Dahltsrorn, also a ? , the wings are wholly tinged with blue, the costa of the
