AGRIADES CORIDON. 57 



3rd ed., p. 86, " caerulea ; Armenia, Pontus orientalis." Oberthiir 

 notes (Etudes, xx., p. 20) that the form known as caucasica, Led., is 

 of a more unpolished and less brilliant blue than that of adonis, and is 

 distributed in Syria and Transcaucasia. :;: The Borjom examples in the 

 British Museum coll. are very large, and much nearer tlietis (bellargus) 

 in tint than any other examples of A. coridon examined. Eiihl 

 notes (Pal. Gross- Schmett., p. 278) " the $ as being of a more sky- 

 blue ground colour, with very narrow black border, which almost 

 always has the appearance of a line only. The spots at the border of 

 the hindwing much smaller than in the type. The rings, which on 

 the underside surround the discoidal lunule and the eye-spots, are on 

 the average larger, and the red bordering of the hindwings lighter. 

 Locality — the Caucasus, Armenia." Neustetter notes (Int. Ent. Zeits. 

 Guben, iii., p. 198) under the name corydonius, an Armenian ? with 

 the violet-blue colour of the g (parallel, therefore, one supposes with 

 tithonus, Me-ig.) which he names caerulea.

 Seitz, "Gross-Schmett.," i., 315, pi. (1909).— Var. ossmar, Bischoff. Turkey. 

 This variety, occurring likewise only very rarely, I received through Bischoff, who 

 took it in Turkey (Gerhard). 



This is a mere aberration of $ caucasica, noted in Lederer's original 

 description of that form (antea, p. 56) as " having the marginal border 

 of the fore wings indicated merely by some black scales." These are 

 usually in the form of intemeural dots, as in the hindwings, but the 

 dots take rather a blotched form by union with the outer marginal 

 line, although in some quite distinct and separate from the margin. 

 The hindwings are exactly as in var. caucasica. The $ ossiuar as 

 figured by Gerhard, is brown with discoidal spots, but no fulvous 

 lunular markings on forewings ; orange-coloured lunular markings 

 appear, however, on hindwings.

 "111. Zeits. fiir Ent.," ii., p. 47 (1897).— Corydonius, Kef., suppl. figs. 595-6, from 

 Turkey, must be as good a species as polonus. The blue differs from that of both 

 (corydon and^oZonzts); the black border of the forewings is as wide as in polonus, 

 but carries large black spots between the nervures on the hindwings ; the spots are 

 as in this species, but the marginal line forms a more noticeable angle at the 2nd 

 nervure, and does not enter in such sharp points between the interneural spots. 

 The fringes of the forewings are very strongly chequered with black. The under- 

 side agrees entirely with my fig. 353,+ except that the forewings are more whitish, 

 and the marginal spots of the hindwings larger, whilst the black pointed hooks 



* There is no doubt that the J noted (p. 20) as being captured at Vernet-les- 

 Bains, and figured pi. iii., fig. 29, and the other taken at Cauterets in July, 1882, 

 are two more examples of true A. hybr. polonus, Zell. 



f Heydenreich's work (dated 1851) quotes the name ossmar as Kindermann's, 

 while Gerhard, writing in 1852, gives it as Bischoff 's (Wheeler). These are, of 

 course, MS. names. 



I Fig. 353 represents a <? A. coridon, underside with dark forewing and yellow- 

 brown hindwing. Forewing with three basal spots. All the spots rather small, no 

 black centre to the discoidal of the hindwing, the lower corner of which joins the 

 white streak (Wheeler).
