SEASONAL POLYMORPHISM. 15 



the Valdieri race. The females differ still more from each other 

 and resemblance never occurs : at Klausen their black markings are 

 more extensive than in the male ; in the other race they are, if 

 anything, less extensive. This, of course, is due to the usual rule in 

 all the Arminniili races of the Alps, as compared with those of Central 

 Italy. In this case, as in the others, a striking feature is the total or 

 nearly total absence in the latter region of the dark basal suffusion on 

 all the wings in both sexes. Other features of my new race, besides 

 the notable further accentuation of the characters given by Friihstorfer, 

 are its larger size than nikator and the particularly pale, dull ochreous 

 yellow of the female, which increases the sexual dimorphism. What 

 is surprising is that daplnie at the Baths of Valdieri should be the 

 same as in Central Italy, whereas niobe, L., and atjlaja, L., produce in 

 that locality their Alpine characteristics to a high degree and differ 

 most markedly from the races of Central Italy by the extent of their 

 dark markings. Friihstorfer was right in saying the Valais race is 

 still more striking than the one of Klausen. Judging from specimens 

 collected by Wullschlegel at Martigny, it is intermediate between the 

 two races described, but it comes nearer to my new, culminating one 

 than to the Klausen nikator. I propose restricting this name to the 

 latter and calling the other teniiitenimcHlona, taking as " typical " my 

 series from the neighbourhood of Florence. The Martigny race could 

 be designated as teimitermacnlosa trans, ad nikator. It will be noticed 

 that in this species again the Calabrian race goes back to the darkest 

 Alpine race and contrasts with its near neighbour of Central Italy. 



Ariii/miis niobe, L., race rubida, Vrty., trans, ad appenninira, Vrty. 

 —In the Bull. Soc. Ent. Ital, xlv., p. 214, pi. I., fig. 8 (1914), I 

 described the beautiful race discovered by Querci at the Piani di 

 Carmelia, m. 1200, on the Aspromonte, which is a near ally of 

 knhlmanni, Seitz, from the Black Sea, and I described {I.e., p. 218, 

 pi. I., fig. 6 and 7) the race from Central Italy, which contrasts sharply 

 with it. The race of the Coast Range (Le Crociate, m. 900 to 1000, 

 above S. Fili) has, as usual, the Calabrian characteristics to a lesser 

 extent than the Aspromonte one, but in the case of this species, 

 instead of approaching the race of the Alps, it is transitional to the one 

 of Central Italy, probably because rubida itself is oriental in character 

 and not similar to the Alpine race, as is the rule in the other species. 

 At Le Crociate the fulvous is slightly more reddish than in appenninica, 

 but far from the beautiful carmine tinge of rubida ; the black markings 

 are intermediate in extent ; the underside of hindwings has traces of 

 the rust-coloured spots, but paler and less extensive than in rubida and 

 often mixed with the green, which replaces it in appenninica ; finally, 

 one male specimen has been found with all the silver spots present, 

 whereas no rubida of this sort has been detected amongst the large 

 numbers collected on the Aspromonte. 



Arfpjnnifi aj/laia, L., race locupletata, mihi, =Zoc»/*^t'.s, Vrty. [Ent. 

 Rec, xxxi., p. 195] . — I propose this new name to replace that of 

 locuples, which I was sorry to discover had already been applied by 

 Butler to an Aryynnia of the species usually called adippe, L.
