SEASONAL POLYMORPHISM. 47 



are three broods, and the second and third are much more distinct 

 from the first, not only by a greater constancy and prominency of the 

 characters of parvipiincta, as described by Fuchs. but by their larger 

 size and by the much greater extent of the black marginal band in 

 the female ; I should restrict the name of Fuchs to the second brood 

 of Central Europe and name the southern second and third canicu- 

 LARis, mihi. It must furthermore be noticed that also the first brood 

 differs markedly in the south from the northern one by its larger size 

 and warmer, less silvery, colouring, so that it is well worth distinguish- 

 ing by the name of calidogenita. 



The race of the British Islands varies in an exactly opposite 

 direction, if I may be allowed to judge from a series of specimens 

 collected in May at Woodford in Epping Forest ; they are of an 

 exceedingly bright blue, very cold in tone above ; on the underside 

 the blue basal suffusion is vivid and expands to an extent it does not 

 reach even in the nymotypical northern race ; the little black dots and 

 streaks are much more prominent ; I also notice a female form of the 

 7th of May, which certainly never occurs in the south ; in this form 

 the underside characters of the first brood mentioned above are asso- 

 ciated with a very wide marginal black band on upperside, such as is 

 only found in jmrvipuncta or calidogenita (female form, mixta, mihi.). 



Ciipido miniums, Fuessl., race trinacriae, mihi. — Querci has col- 

 lected in Sicily (S. Martin delle Scale, m. 700) in April and May a 

 very distinct race of this species ; it is the smallest known, never sur- 

 passing 18 mm. of expanse and frequently being as small as 14 mm. ; 

 there is never any trace of metallic scaling at the base of the wings 

 on the upperside in either sex and the colouring is of a dull, greyish 

 black, lighter than in other races. 



Cupido sebrus, Boisd., race angulosa, mihi. — A female I have col- 

 lected in the mountains of Tuscany (Firenzuola, m. 500), and others 

 collected by Querci in the Sibillini mountains (Piceno) are remarkable 

 on account of the shape of the wings, the hindwings forming a dis- 

 tinct angle on the second cubital nervure ; it is evidently a mountain 

 character ; the males are distinctly smaller than the usual ones of 

 the plain and the black markings on the underside are more minute. 



Everes alcetas, Hiib. — Seasonal dimorphism is not so marked in 

 this species as in argiades, Pall., but the first brood is generally smaller 

 and pale specimens occur, such as are never found in the second ; the 

 name diminuta, mihi., seems appropriate to the former. Hiibner 

 states particularly that there is no trace of the orange lunules on the 

 underside, so that specimens bearing traces of such lunules can be 

 designated by the name luteumfera, mihi, although in the figure of 

 that author they do exist. 



Theda (Nordtnannia) ilicis, Esp. — Oberthiir rightly observes that 

 Staudinger has made a blunder in using the name esculi of Hiibner 

 for the aberration of ilicis in which the white streak on underside is 

 missing, the figure of that author clearly representing another species; 

 the name alineata, mihi, can be substituted.
