AGRIADES CORIDON. 23 



when we wrote our little volume on British Butterflies, in 1896, we 

 neither knew Zeller's description, nor had we examined his types. 

 Further, we had no knowledge of hispana, except from the erroneous 

 diagnosis in Staudinger's Catalog, 2nd ed., p. 12, and it happens that 

 the examples that we chose to represent our hispana, bear no resem- 

 blance to the true hispana, but are the picked examples of many British 

 captured individuals, that most closely resemble Zeller's types of ab. 

 apennina. They resemble them in the pale silvery-blue ground colour, 

 in the pale outer margins of the forewings, in the pale-edged, grey- 

 centred, interneural marginal spots in this pale marginal area, as well as 

 in the rather better denned marginal spots on the hindwincs. On the 

 underside, too, they are very similar, and when Zeller described his types 

 as pale, it was only by comparison with some much darker type that he 

 carried in his mind. As a matter of fact the undersides are not paler 

 than those from many other districts, not so pale, for example, as the 

 albescent forms from such distant localities as the Trafoi-thal and the 

 Ye neon Yalley (Bourg d'Oisans). This evidently misled Schultz who 

 states (Jahresb. Wien. Ent. Ver., xvi., p. 76) that his " limbomaculata 

 only differs from apennina in the fact that the underside agrees 

 entirely with the type," which is quite exactly what Zeller's 

 types of apennina do. It will be gathered from this, therefore, 

 that the name apennina is somewhat of a misnomer, inasmuch as 

 the types do not represent a varietal race, but merely two pale 

 examples, occurring on ground where more typical forms are also 

 found. It is merely an aberration, and may be taken occasionally 

 anywhere with other quite different forms. Weiler states (Schmett. 

 Innsb., p. 9) that specimens strongly approaching apennina are met 

 with in the Tirol, and Neustetter's description of altica {Int. Ent. 

 Zeits. Guben, iii., p. 19H) also appears to refer to specimens approaching 

 or agreeing with this form.

 interneural marginal spots to fore- and hindwings (Tutt). 



In our very bright blue $ s, it occasionally happens that the 

 margin of the forewing has no definite black border, but, instead, the 

 series of interneural spots, usually almost lost in the dark border, stands 

 out nearly as clearly as those of the hinclwing, with little or no failure 

 in the intensity of colour, and almost as strongly bordered ; specimens 

 of this form, with the margins of the forewings ornamented with 

 ocellated spots similar to those of the hindwings, comprise our punctata. 

 It is fairly abundant on the Kentish downs — Hailing, etc. — and South 

 notes it as frequent at Ventnor. Wheeler notes that Barrett gives (Lep. 

 Brit., i., pi. xii., fig. If) a $ with spots showing in the band, fore- and 

 hindwing. Aigner-Abafi reports it from Budapest and Isaszegh ; J 

 specimens in which the marginal bands of forewings are practically 

 obsolete and the marginal spots clearly distinct, occur at Digne 

 (Rowland -Brown) ; Haverkampf records it from Torgny in Belgium.
