AGRIADES CORIDON. 47 



somewhat mottled appearance ; the fulvous crescents, too, are somewhat brighter ; 

 in others, again, the ground colour of the forewings is almost blackish-grey, the 

 hindwings with a considerable amount of brown in the ground tint ; a few are 

 paler grey, and both in tint and spotting very like typical Central European 

 A. coridon ; only some 6 s s out of 60 <T s are of the whitish, mottled form 

 described above, although others are near enough to be difficult to determine as to 

 whether they should be placed here or not. The spotting of the underside 

 comprises examples of cinnus, Gerh. , juncta (via addenda), semiarcuata, etc. The 

 ? s are deep fuscous-brown in colour, resembling in their browrmess ? s from Susa 

 (Piedmont), the ? s of var. hispana, and being decidedly less blackish-fuscous than 

 the usual Central European ? forms ; they vary much in the development of the 

 marginal lunules, and include the forms subaurantia, peraurantia, and aurantia. 

 The short black discoidal of the forewings is well-marked, there is often not one notice- 

 able on the hindwings, and there is no blue scaling. The underside of the ? s is 

 very dark grey- brown, the hindwings scarcely, if any, browner than the forewings ; 

 the spots well-developed and clearly ringed with white; one exhibits well the 

 characters of ab. externa, the 2nd-4th submedian spots elongated, the lower half of 

 the discoidal and the upper basal lengthened, whilst the lower basal and the 7th 

 and 8th subrrredian spots unite into the biarcuata form ; two others are of the 

 parisiensis form, four of the ab. addenda in varying degrees, one being well towards 

 the antico-juncta form ; it is to be further noted that occasionally they bear the 

 complete row of eight submedian spots on the forewings ; the marginal ocellations 

 are well-developed, the orange lunules bright on the hindwings, weak on the fore- 

 wings, in which, however, the grey chevrons are sometimes very strongly developed. 

 The metallic scaling on the underside is well-developed at the base of the hind- 

 wings, blue in the <$ s and golden in the ? s. 



It appears that our meridionalis comprises examples that are refer- 

 able to rezniceki and others to constanti, whilst others seem to fall quite 

 outside either. Most of the specimens from Ste. Maxime and 

 Draguignan agree with those described by Reverdin, but both these 

 places also give examples that correspond with rezniceki in the 

 particular pale ground colour of the underside, which forms the 

 essential distinction between the latter form and constanti (teste 

 Reverdin); in addition meridionalis includes $ s which have the under- 

 side ground colour much darker, and the hindwings much browner 

 than that mentioned in either of the other descriptions. Whether, 

 therefore, these various Rivieran forms are really racial or overlap, is 

 a matter for future enquiry. Our remarks on meridionalis are based 

 on a series of 60 $ s and 17 $ s taken at Ste. Maxime, Draguignan, 

 and Hyeres. In no way does Bartel's colour-description of $ rezniceki 

 agree with that of var. meridionalis, which is pale silvery-blue in tint, 

 nor is his reference to var. apennina understandable, as there is no 

 special Apennine race of A. coridon (see antea, pp. 22-23); the forms 

 agree on the whole in having a broad marginal border, but meridionalis 

 by no means has this in every case, that of some specimens being very 

 narrow ; nor is it, in the latter, bounded by a conspicuous row of 

 whitish arcuate spots as described in rezniceki ; these frequently, when 

 present at all, divide the broad margin lengthwise, whilst in others 

 they are quite absent. The darkening of the discoidals is far from uni- 

 versal in meridionalis, and even when marked they are often very incon- 

 spicuous. The marginal spots on the hindwings are large in meridio- 

 nalis, but not so amazingly so as Bartel's description suggests in 

 rezniceki. The underside of the $ s of meridionalis is very variable, 

 the colour is occasionally as light as described by Bartel for rezniceki, 

 more often like that noted by Reverdin for constanti, but frequently 

 much darker than in the latter ; the forms agree in the strong develop- 

 ment of the metallic blue scaling at the base of the hindwings, and by
