9. Pieris napi atlantica, subspec. nov. 



The form found at Blida les Glacieres and in the Kabylie is very distinct. 

 It differs from European specimens by being ver}' white above, as the vems 

 are not marked with black or grey and the black spots on the forewing are 

 very much larger, and below there is hardly any trace of the green on and around 

 the nervures of the hindwing. AVe our,,selves have only taken it at Blida les 

 Glaciere.s, but Dr. Nissen has taken it in the Kabylie, and I have one said to 

 have been taken by Faroult in Tunis. My single Moroccan specimen has more 

 pointed forewings and is more yellowish above, but I cannot judge from one 

 specimen. Mr. Gibbs records napi atlantica also from Blida. We have of this 

 17 at Tring.

In the British Museum there are no specimens of 7iapi from North-west 

 Africa. 



Miss Fountaine records it in May both from Blida and Teniet-el-Haad. With 

 the exception of L. glauconome and Teracolus chrysonome, this is the rarest of 

 the North African Pieridae, though G. rhamni is not much commoner. 



10. Leucochloe glauconome glauconcme (Klug). 



Pontia glauconutne Klug, Symb. Phys. Fol. h. No. 12. T^ib. vii. flf. 18. 19 (1829) (Mount .Siaai, on 

 Erigerum denticulatum). 



Before Dr. Ernst Hartert obtained the two specimens enumerated below, 

 the only Mauretanian record was the specimen obtained by the late Roland 

 Trinien at Constantine. The two mentioned below and two from Assouan are 

 all we have at Tring of true glauconome.

11. Leucochloe daplidice albidice (Oberth.). 



Pieris daplidire var. albidice Oberthur, Etiid. d'Entom. Fasc. VI. p. 47 (1881) (Algeiie, Prov. Con- 

 stantine Sud). 



Mr. Charles Oberthiir, in hLs Etudes de Lepidopterologie Comparee, Fasc. 

 III. pp. 122-125 (1909), has pointed out that Esper and Freyer's Pieris raphani, 

 which Staudinger and most of us following him accepted as bemg the southern 

 race of daplidice Luin., and therefore having priority over Oberthiir's albidice, 

 is really Belenois hellica (Linn.). This was also known to the late Mr. W. F. 

 Kirby, for we find in his Catalogue of Diurnal Lepidoptera, p. 452, raphoni Esp. 

 as a synonym under hellica. 



In my article on Dr. Hartert's de.sert trip, Nov. Zool. vol. xx. pp. 110-111 

 (1913), and in Nov. Zool. vol. xxi. pp. 299-330 (1914), ui the preliminary 

 account of the fauna of Guelt-es-Stel, I most unfortunately committed another 

 mistake ; for although I did not commit the error of mistaking raphani for 

 albidice, I used it for the form of daplidice inhabiting the northern and southern
