AGRIADES CORIDON. 51 



At Ste. Maxime and Draguignan, therefore, the forms appear to over- 

 lap, or to contain the elements from which may be developed the pale- 

 underside rezniceki, the dark-underside constant!, or something much 

 darker than the latter. We would note that Bartel does not appear to 

 say, as stated above, that rezniceki is " whiter beneath than the type," 

 this must be considered simply as Reverdin's rendering of Barrel's 

 " tolerably pale," etc.

 cinereo albidis, margine externo punctato apiceque nervorum fuscis (<?); 

 anticis puncto medio nigro, posticis lunulis fulvis-obsoletis ( ? ); subtus albido- 

 luteis lineis duabus e punctis ocellaribus punctoque medio nigris, lunulis fulvis, 

 obsoletis, anticis fimbria nigro-maculata. This species exhibits the same 

 peculiarity as dorylas, but in a less pronounced manner ; there are some examples 

 quite whitish with the spots of the hindwings almost entirely effaced ; the form is 

 not rare on the hills in the neighbourhood of Granada (Kambur). 



This is the beautiful large white local race of Andalusia, named 

 albicans, in 1840, by Boisduval, but described at length the preceding 

 year by his friend Rambur. There is an excellent series of S s in the 

 British Museum coll., labelled " Granada (Ribbe)," " Spain, Leech 

 coll." 5 $ s, "Andalusia, Zell. coll.," and we have 1 $ and 3 £ s also 

 from " Granada." These are true albicans, whiter than any other 

 known form of the species, with long, silky hair-scales, resulting in 

 the almost entire absence of any metallic scaling or sheen ; the margins 

 weakly-spotted exactly as Rambur describes and Gerhard figures them; 

 the undersides also most obsoletely marked on pale creamy- white ground 

 colour and obsolete orange chevrons. Gerhard's is, indeed, a good 

 figure of this race, except that it does not show its usual large size. 

 Besides Rambur's description, quoted supra, he notes (Cat. Syst. Lep. 

 de VAndal.,^. 42) that "similarly to that of dorylas, the, colour of 

 corydon is modified by the heat in Andalusia, and produces a variety 

 albicans, i.e., a greyish-white form, scarcely at all bluish, and with the 

 black portion of the margin of the forewings tending to disappear, the 

 form being common throughout Andalusia." Milliere states (Icon., 

 p. 84) that " albicans is peculiar in being generally a third larger than 

 ordinary corydon, the usual silvery shiny- blue only indicated on the 

 upperside at the base of the wings, whilst the marginal ocellated spots, 

 without fulvous lunules, are less marked on all the wings than in the 

 type form ; beneath it is very pale, and the fulvous lunules so well- 



* Although on the title-page of Gerhard's work the date is given as 1853, 

 Heft 1-3 were published in 1850, Heft 4-5 in 1851, Heft 6-10 in 1852. His vars. 

 of A. coridon are quoted by Meyer-Dur, whose work was published both in the 

 Ziirich Magazine and separately in 1852, not in 1851, as erroneously noted in the 

 Nat. Hist. Museum copy of the work from which our previous dates have been 

 taken.
