brown, and with stronger blue suffusion at the base. The 3 then is specially- 

 distinguished by the unusual colouring of the wings, the very large, strikingly 

 broad, light-bordered, marginal spots of the hindwing, and still more by the 

 different underside of the wings, which approaches so closely to A. bellarpus that 

 one can easily mistake an unset specimen, whose upperside has not been seen, for 

 the latter species. In its colouring, the <? inclines towards var. hispana, H.-S., 

 but the blue of the upperside is different, the border is darker, and the black 

 discoidal spot wanting, the hindwing on the underside is of a darker ground colour ; 

 in the 2 of var. hispana, the discoidal spot on the hindwing does not stand out so 

 strongly ; the row of red spots is much stronger, the underside of the forewings 

 darker. The ? of var. albicans, H.-Sch., is of one shade, much more thickly 

 scaled, and the brown sheen entirely absent ; the discoidal spot of the forewing is 

 darker and thicker, but does not stand out so strongly; it has only very weak red 

 spots or none at all ; on the other hand, the ? of var. albicans has a more con- 

 spicuous marginal row of black spots than the new form ; the underside is equally 

 brownish, the light margin of the spots more indistinct, less conspicuous, the 

 spotting itself is weaker ; this is most conspicuously so with the marginal row ; the 

 greenish suffusion at the base and on the inner margin of the hindwings beneath, 

 is not perceptible in var. albicans. The ? s of var. corydonius, H.-Sch., and var. 

 caucasica, Led., have no antemarginal red spots on the forewing, the latter form is 

 also much darker, without discoidal spot on the hindwings. and only very weak 

 dark red spots on this wing : the discoidal spot on the forewing is also much 

 smaller ; the underside of the forewing is darker, the spotting conspicuously 

 weaker, most strikingly at the margin. Expanse: s 29mm. -30mm., 2 29mm.- 

 31mm. Locality: Rapallo (Italian Riviera), June Ist-lOth, 1904 ; Monte Carlo, 

 June 10th-13th, 1904; also from Bordighera and Xice. Taken by Herr von 

 Reznicek (Bartel). 



This description of Barter s is most confusing owing to what appears 

 to be an entire misapplication of names to the forms with which he 

 attempts to institute a comparison. He certainly fails to recognise ab. 

 apennina, Zeller, hispana, H.-Sch., albicans, H.-Sch., and corydonius, 

 H.-Sch., and his references thereto make his comparison worse than 

 useless. His eorydonius appears to be a mixture of the true hispana, 

 H.-Sch., and ohjmpica, Led., his hispana our caerulescens, his albicans 

 our arragonemis, Gerh., etc. Apart from all these probably erroneous 

 references to races as widely different from the Bivieran specimens as 

 is possible within the species, one wonders what purpose is served by 

 a comparison of forms so utterly unlike. In its broad outlines, one 

 assumes from the description that rezniceki is like the other Rivieran 

 forms, yet there is hardly a point laid down as diagnostic, in which 

 meridionalis, at least, does not differ. We have already discussed 

 (antea, pp. 46-48) most of these points, as far as our material allows. A 

 •careful diagnostic description of rezniceki, stripped of unnecessary 

 verbiage, is still a desideratum. 



y. var. vern. constanti, Reverdin, " Ent. Rec," xxii., p. 60 (1910). — Agriad.es 

 coridon var. constanti, gen. preecox. — Upperside : General ground tint less vivid 

 and brilliant than in typical A. coridon, this tint is slightly greyish; if one places 

 side by side two series of A, coridon, the one of the ordinary form, the second of 

 those from Pardigon, those of the latter appear noticeably duller and more greyish. 

 The forewing generally shows a small black line, more or less well-marked, at the 

 ■extremity of the discoidal cell ; the grey marginal border is broad, and often shows 

 a series of dirty white lunules in its centre. The hindwing is ornamented along 

 its outer margin with eye-spots, which are generally complete, i.e., formed by a 

 large black point surrounded by a whitish ring, which is whiter in the part border- 

 ing the black point externally, and is generally blackish-grey internally. Under- 

 side : The ground colour, instead of being whitish as in the type, is grey, and of a 

 very marked grey, scarcely at ail browner on the hindwings, whilst in the type the 

 two wings differ much from one another as a rule, the hindwing being yellowish, 

 the forewing whitish. The margin of all the wings presents a complete series of 

 black points encircled by white, these eye-spots are on the hindwings surmounted 

 by orange lunules, bordered in turn internally with little black chevrons; on the
