THE ENTOMOLOGIST S RECORD. 



by its notably smaller size and by tbe distinctness of the white spaces, 

 especially as regards the premarginal series, always quite complete and 

 prominent. A couple 1 possess from Saal on the Danube seems to 

 correspond to this race, so that one cannot say in an absolute way that 

 Hiibner's race is the one of Central Europe and that the smaller one 

 is the southern race, although on broad lines this seems to be the case. 

 I observe that the specimens of the second generation I collected 

 myself at Atzwang at the end of July are distinctly smaller than the 

 spring ones, obtained from Wagner, of the same locality ; they are, in 

 fact, only just a trifle larger than the first brood subgracilis of Central 

 Italy, differing from it by the characteristics mentioned in connection 

 with the white spaces, of which the premarginal row is nearly always 

 faint and incomplete and often entirely absent, a feature I find, only in 

 two mountain specimens out of the 87 in my collection from Central 

 Italy. The expanses of wings, between the tips at the beginning of 

 fringes, are the following : spring sao from the Isarco Valley : 

 22-24nim. ; "types" of /larrula from Atzwang : 20-21; "typical" 

 series of subgracilis from Florence (N. 1 to 31 in glass mounts) : 18-20 ; 

 " typical " series of gracilis from same locality and from the Fegana 

 Valley, near Lucca : 16-18. 



Loiceia alcipliron, Rott., race calabra, Vrty., trans, ad romanorum, 

 Fruhst.— At S. Fili, m. 900, on the Coast Range of Calabria a race 

 was found transitional from race calabra, Vrty. [Bull. Soc. Ent. Ital., 

 xlv., p. 229, pi. I., fig. 43 (1914)], to race romanorum, Fruhstorfer 

 [Intern. Ent. Zeit., iii., p. 112 (August 14th, 1909)], the first 

 discovered by Querci in the Piano di Carmelia, m. 1200, on the 

 Aspromonte, the second described from specimens of " the neighbour- 

 hood of Rome " and generally distributed in the whole of Central 

 Italy, except where it is replaced locally by mirabilis, Vrty., or by a race 

 transitional to the latter, rnehli, Trti. [Societas entomologica, xxv., 

 p. 83 (January, 1911)] , described from " Cerchio and Celano " in the 

 Abruzzi and which might well be called mirabilis trans, ad romanorum. 

 In the S. Fili race the males resemble those of romanorum by the clear 

 ground colour and small black spots ; the females have not got the 

 clear copper tinge of those of calabra, but are suffused sparsely with 

 dark scales on all the wings or on hindwing only, in which case they 

 approach form intermedia, Stefanelli ; this suffusion is never, however, 

 as dense as in most romanorum from Central Italy. 



Aricia chiron, Rott. ( = eumedon, Esp ), race glaciata, mini. — In the 

 magnificent little valley of Sulden, m. 1800, in the meadows at the 

 foot of the moraines of one of the huge Ortler glaciers, in company 

 with the tiny, dark, nymotypical A. medon, Hufn., I collected, from 

 August 3rd to 10th, 1920, another small insect, which, at first, rather 

 puzzled me. It was only when it was set and I compared it with the 

 specimens in my collection I realised it was a chiron, so different did it 

 look from this species, which, as a rule, varies scarcely at all 

 geographically ; it resembles incredibly the female of P. donzelii, B. 

 What gives the Sulden race such a peculiar aspect is chiefly its 

 diminutive size, which seems as if it were scarcely half the usual one, 

 the actual expanse being 21 to 23mm. instead of 25 to 29; the shape 

 of the wings is less elongated ; the colour has a washed out greyish
