 bfi found, at some future time, that the large.st Oiied Mya examjjle is an accident, 

 the Sonth Saharau form will have to he separated. lu 19uS and 1900 we fonnd 

 this species numerous round Riskra, and in 1011 enually so at (Jhardnia, but it 

 never was found anywhere except in the immediate neighbourhood of the thorny 

 Jujubiers, Zi.:i/pli>is lotus. 



[We found T. ti'op/irna/t/s common in the Oued Nca, and still more so near 

 Ghardaia and in the oueds south of (Jhardaia, as far as Z/.:'//j/iii.s lofiix occurred. 

 Together with Zi:i/i)liiix this butterfly was absent from all the country traversed 

 from Chegpa to Touggonrt and i'rom Touggourt to El-Golea, also from Rl-Hadadra 

 to Kl-Golea, and thence to the Oued Mya, where /.izi/plmx rea|)poared. They were 

 always difficult to catch, as they kept closely to the bushes, whi(^h, on account of 

 their tliorns, were forbidding for our butterfly-nets. — E. II.]

The Igosten specimens are on the average considerably smaller than the 

 Touggourt ones, but here again at present 1 do not venture to separate them. In 

 1',MI8 and 1900 we caught this little insert in I'dskra and Touggourt, but we did not 

 sec it in 1011. 



[Except for a few sj)ecimens in the Southern Oued llya we never saw this I'lue 

 in other places than the gardens in the oases. — E. H.] 



10. Lycaena astrarche cramera Eschsch. 



1 S, Sands of El-Arich. 



A. aafrnir/ir is widely spread, reaching from the Canary Islands on the west to 

 the Isle of Askold on the east, and Northern Scandinavia and Siberia in the north 

 to the (Vntral Sahara and North India in the south. The ])resent race appears (o 

 be conlined to the Canary Islands anil Xorth-West Africa. 



IT. Chrysophanus phlaeas phlaeas (L.) ab. eleus F. 



1 d", Ghardaia. 



This specimen is a good example of the tailed ab. rtn/s, but the bulk of the 

 specimens of this widespread butterfly which have been taken in .Mgcria are ordinary 

 p. pill It I'll K. It is found all over Algeria, though it is nowhere abundant.

The only specimen we ever caught of this genus during our four expeditions in 

 Algeria.
