AGRIADES CORIDON. 27 



Specimens in the British Museum coll. from Florence (May 3rd, 

 Stefanelli), Saas-Thal (Godman), are similarly marked ; the most 

 strongly marked is one labelled, " Mutzell coll. Berlin," and corre- 

 sponding otherwise with ab. margmata, Tutt ; others more slightly 

 marked are labelled Eggenthal (Sampson), Esino (Elwes), Britain 

 (Stevens), Pegli and Kokaleny. Aigner-Abafi reports it from Buda- 

 pest and Isaszegh. Neustadt and Kornatzki, in tbeir Schwetterlinge 

 Sc/desims, figure what they evidently regard as typical $ coridon, 

 with very strongly marked orange chevrons, pi. xxi., figs. 69a and c. 



\. ab. (? et var.) graeca, Buhl, "Pal. Gross-Schmett.," p. 763 (1895); Courv., 

 " Soc. Ent.," xii., p. 26(1897); Lamb., "Pap. Belg.," p. 239(1902); Bartel, 

 "Ent. Zeits. Gub.," xviii., p. 117 (1904); Seitz, " Gross-Schmett.," i., p. 315 

 (1909). — Allied very closely to var. apennina. <s with paler uppersicle and strong 

 greenish-silver gloss; forewings with blackish-grey border without white spots. 

 Underside very washed out, even more so than in var. apennina (Biihl). 



This seems a most unfortunate cognomen, and apparently Riihl has 

 given a racial name to an odd $ in his possession, for in no particular 

 does his description show any approach to Zeller's apennina. These 

 latter are silvery-blue, not " silvery-green," their chief character is the 

 pale, spotted margin of forewings, not " blackish-grey unspotted," 

 whilst the underside spotting in apennina is almost typical, and not 

 " washed-out." [Zeller, by-the-bye, must have had some remarkably 

 strongly-spotted specimens with which to compare when he was writing 

 his description of apennina.] Strangely, the only two $ specimens in the 

 British Museum coll. from Greece, labelled " Merlin coll.," are almost 

 identical with Zeller's apennina, and disagree in almost every particular 

 with Buhl's description of graeca. In the present state of our ignorance, 

 Buhl's description is not applicable racially to the known Greek 

 examples. Courvoisier notes taking an example on the Simplon Pass, 

 in 1895, that came near graeca. Bartel mentions a £ in his collection 

 belonging to graeca, the underside being of the parisiensis form. 



ju. ab. glabrata, n. ab. — All the wings pale blue, but with a peculiar smooth 

 appearance [almost as if slightly greased] ; this appearance being due to the 

 absence of the long white hair-scales which characterise the species. 



Two striking $ s in the British Museum coll. are of this form — 

 (1) Blue-grey in tint, very smooth in appearance, strong marginal 

 border to forewings ; the hindwings also with a strong border, showing 

 traces only of the three lower interneural spots, labelled " Spain, 

 Leech coll." It is very different from any of the Spanish local forms 

 described (postea) and one suspects that it must have come from northern 

 Spain where the species is more typical in appearance. (2) A slightly 

 larger example, labelled " Eggenthal, July, 1906, Hampson," only 

 differs in having traces of the whole row of interneural spots on the 

 outer margin of the hindwings. We have very similar examples in 

 our own collection. 



v. ab. transparens, Eebel, " Berge's Schmett.," 9th ed., p. 72(1909). — The 

 spots of the underside showing through on the upperside. Both sexes. 



£. ab. metagrapha, Spannert, "Wiss. Benen. Eur. Gross-Schmett.," p. 29 

 (1888). — Distinguished by its aberrant colouring and marking (Spannert). 



This name comes from a book which is merely a list of names with 

 their weaning, and does not originate any names at all, nor give the 

 authors from whom they are taken. We have so far been quite unable 

 to trace its origin.
