T. Euchloe charlonia charlonia (Donz.). 



10 (?(?, 1 ?, Bordj Oliegga ; 2 (JcJ, Ourir; 1 c?, N^a ben Rzig. 



This species varies much in si>:e; but there .appear to be no sejiarable sub- 

 species till we get to Asia Mioor and S.yria, wlieu we find charlonia charlonia 

 replaced by ch. penia in Asia Minor, ch. transcaspica from Turan, rh. liirilhi Butl. 

 from West Himalayas, and two undescrihed Indian forms. 



A specimpu, evidently wiud-i)liiwii, was taken by Captain HoU in Hussein 

 Dey, a suburb of Algiers town. 



[In lOiji), in March and April, wben riding twice througb the same countries, 

 we never saw a sign of this species, while in 1912, late in February, it was quite 

 common near Bordj Chegga, and extended as far south as Tamerna in diminisliing 

 numbers. — E. H.] 



8. Teracolus daira nouna Luc. 



13 c?(?, 4 ? ?, Ghardaia. 



This beautiful little butterfly is found in the northern portion of the .Sahara 

 wherever its food plants (^ipparin droserifoUa and spinosa occur ; it a[ipears to 

 reach larther north in \Vest<M-n Algeria, as Miss Fonnfain records it from Sebdon. 

 Lucas described it from tiie Algerian spring generation, which corresponds to the 

 wet season form of the tropical 7'. daira daira. This led Rober to consider it 

 as the winter form of il. dnirn, which, however, it certainly is not, as the two 

 summer forms are abundantly distinct. This confusion of the two wint'^r broods 

 by Rober has led, unfortunately, to the western form being renanied hiacraensig, 

 and thns beconjing burdened with a useless synonym. T. daira daira is abundant 

 in the Egyptian Soudan and Abyssinia, but whether Arabian and Somali specimens 

 are different still remains to i)e settled. T. dnira nouna is Iconfioed to North-west 

 Africa, and the summer generation ii not very different from the spring brood. 



\^T. daira. noiin/i was only seen at Ghardaia. There it was (paite common during 

 the last days of May, lint the majority of specimens were already in very bad 

 condition. Once a great numlier were seen in the early morning sitting on a large 

 |iliint of ('apj)nris .ytinosa, while later in the day, when the sun was out, they were 

 very restless. In 1011, in April, Mr. Rothschild and Dr. Nissen caught three 

 sjiecimeas, in poor condition, and those were all that were seen. — E. H.] 



'••. Colias electo ci'oceus I'onrcr.

Our well-known < 'louded Yellow has an enormous breeding range if wo take 

 in C. electo as a whole — viz., from the Canary Islands on the west to Somaliland and 

 Persia on the east and from Eiu'opc south of the Alps and Pyrenees in the niu'th to 

 ( 'apctown in the south. The Palaearctic form croceus Fonrcr. = ednsa, Fabr. is 

 confined to the countries north of the south boundary of the Sahara, and although 

 it goes north to Great Britain and North Germany, it is ouly as a wanderer, i(n' 

 it is not found as a resident species north of the Alps, ('.electa electo Linn. 

 ot:cnrs all over Africa south of the Sahara and on the Canary Islands ; it i.s said 

 to have been taken in England, but the record appears duubtful.
