THE ENTOMOLOGIST S RECORD. 



generation hibernata, mihi ; second generation meridiana, mihi. — 

 The nymotypical form of this species, first described by Chapman, is 

 the second generation of a French race, having two broods, but in 

 which no difference was, according to its author, detectable to the 

 naked eye between the first and the second. The microscope revealed 

 remarkable differences in the structure of the scaling, which were very 

 accurately described by Chapman himself a year after the discovery of 

 the species in the Trans. Ent. Soc. of London, October, 1914, p. 809. 

 I think such a distinct form should have a name by which to distin- 

 guish it, and I suggest that of hibernata ; it can be extended to races 

 with one generation only, as Chapman has shown that they are 

 identical with the first generation of the double-brooded ones. In Italy 

 the first generation is equally identical with hibernata, so far as I can 

 make out, but the second generation differs from it considerably by 

 very constant characters, parallel to those exhibited by Polyommatus 

 icariis, Rott., A. thetis, Rott., and"^, aragonensis, Vrty. ; the most con- 

 stant of these is the total absence or very great reduction of the 

 metallic scaling of the underside; then comes the distinctly fulvous 

 tinge, often very bright in the females, of the ground colour of the 

 same surface ; a slight touch of it may be seen also in June specimens 

 of the first generation, but the presence of a wide-spread metallic 

 scaling leaA^es no doubt as to what brood the specimen belongs ; no 

 trace of blue scaling is present in the females of the second brood on 

 the upperside ; this character is also sometimes seen in late June 

 specimens of the first brood ; I propose the name interjeuta for inter- 

 mediate seasonal forms exhibiting characters of the second generation, 

 but having the constant metallic scaling oi the first on underside. 

 The name meridiana mentioned above is no doubt necessary to desig- 

 nate the second brood, different a^so to the naked eye, from the first, 

 and it should be extended to the entire double-brooded races which 

 produces it, taking the Florentine one as nymotypical of it. 



Polyommatus icarus, Rott., race zklleri, mihi, celina, Auat, and 

 first gen. pulcherkima, mihi. Zeller {Isis, 1847, p. 154) well described 

 the southern race as compared to the Central European one of Rottem- 

 burg, but gave it no name. Tutt suggested the name meridionalis, but 

 unfortunately he had already used it for what be thought was the cor- 

 responding form of coridon, and which instead turned out to be a 

 different species {= A. aragonensis, race rezniceki, Bartel) ; this makes 

 it impossible to use the name for any Lycaenidi. I should replace it by 

 the name zelleri, the names vernalis and aestivalis, also of Tutt, holding 

 good for its two broods. Another observation is necessary : the name 

 zelleri must be restricted to the less southern area of Southern Europe, 

 for in the extreme south, such as in Sicily, as well as in Morocco, 

 another race makes its appearance, characterised by the presence of 

 numerous individuals of the form celina, Aust., with a comparatively 

 wide black marginal streak on all the wings of the male, and generally, 

 but not always, as it is erroneously believed, with conspicuous black 

 submarginal dots : the name celina should be used in a general way for 

 the whole of the latter race ; it also differs from zelleri in the first 

 generation by producing also in this brood males with the black dots 

 mentioned above, Avhereas they only occur in the second brood of 

 zelleri; the females are the most beautiful of the species, because they
