306 NOVITATES ZOOLOQICAE XXI. 1914. 



species also at Berrouaghia, mnch to the uortU of Guelt-es-Stel, but otherwise it 

 has, as fur as I am aware, only been recorded from the Anres Moimtains (Batna, 

 Lambessa, etc.) aud El Kantara. 



6. Euchloe charlonia charlonia (Donz.) 



Aiiihocliaris charlonia Donzel, Ann. Sur. Enl. Frame, vol. 11 p. 197 (1842) (Constantine). 



This insect is extremely abundant, and the collection from Guelt-es-Stel con- 

 tains 768 specimens from the mouths of March, April, aud May, and October and 

 November. 



There appear to be two distinct generations, and the one flying in October and 

 November can be distinguished by the much less conspicuous band of yellow spots 

 in the black apex to the forewing. There is little general variation, the series being 

 remarkably uniform. 



The spring generation must stand as 



Euchloe charlonia gen. vern. levaillantii, 

 and the summer and autumn generation as 



Euchloe charlonia gen. aest. charlonia. 



Dr. Stauder in the Zeitschr. Wis$. Insb. vol. x. p. 84 (1914) (El Kantara) has 

 named a late autumn dwarf form atlantica, but it remains to be proved if this is 

 confined to the Southern Aures, for certainly the autumn and summer broods at 

 Guelt-es-Stel are not different in size, the autumn specimens being, if anything, the 

 larger. 



7. Euchloe (Anthocharis) belia (Linn.) (eupheno auct. plur.) 



Papilio helia Linnaeus J , Sjist. Nat. ed. xii. p. 701 ; jj Papilio eupheno p. 762 (17G7). 



This species is fairly abundant and is represented in the collection from the 

 months of April and May. We ourselves only caught a very few in April 1911 and 

 1912, the great bulk having been taken by Faroult in 1913. 



There is considerable variation. Above, the principal differences in the c? cJ 

 occur in the extent of the black tip and black inner band to the orange apex of the 

 forewing; one <J, April 1.'), 1913, having the whole apex almost black; this is 

 the ab. nigritior of Stauder. Below there is a considerable variation in the dark 

 markings and extent of black scaling on the hindwings and in the size of the j^ellow 

 tip to the orange apex of the forewing. In the ? ? above there is a great variation 

 in the extent of the orange apex of the fore wings as well as in the black scaling on 

 this apex ; some females almost approach the Moroccan race androi/yne Leech, 

 and for these I propose the name ab. intermedia. Below the variation is similar 

 to that shown by the o cJ. 



The greater number of authors have always quoted this species under the name 

 eupheno, given by Linnaeus to the S on page 7(32 of the above-quoted work, and have 

 applied the name belia with Cramer as its author to the species which was named 

 ausonia by Hilbner. On page 761, however, Linnaens gives a fairly recognisable 

 description of the S under the name of belia, so it is (piite evident that the name 

 belia must be applied to this insect and not to the spring generation of 

 E. ausonia. 



This insect appears also to be almost confined to the eastern side of the 

 vallev.
