The British Museum possesses 3 from the Meade-Waldo collection- ; 3 

 from Lambessa, May 1882; 1 Constantine, April 1882, J. H. Elwes ; and 2 

 from Biskra, May 1885. 



L. Bleuse ex Oberthiir coll. ex Grum-Grshimailo cfill. Mr. Meade-Waldo 

 in his article quotes Wad Moorbey (nom rect. Oum-er-Rebia), June 1901 ; Sould 

 Jedid and Tsauritz Entsagauz, July 1901. 



12. Euchloe belia (Linn.). 



Papilio belia Linnaeus, Syst. Nat. I. p. 701. No. 84 (1767) (Barbaria). 



Both Mr. Oberthiir and I have declared that we feel sure that the name 

 hdia Liim. applies to the ? of the insect described by him on p. 762 of the above- 

 quoted work, namely euphero Linn., and therefore Cramer's application of it 

 to another insect, which has been followed by Staudiiiger, Dr. Verity, and 

 most other lepidopterists, cannot possibly be accepted. 



Staudinger asserts that belia Linn, is unrecognisable and doubtful, and 

 therefore is a nomen nudum. I have before shown (Nov. Zool. vol. xxi. p. 301 

 (1914)) that the name helia Liun. is not doubtful, and BIi-. Oberthur goes even 

 further by quoting verbatim Lmnaeus' original diagnosis. 



Now, apart from the fact that Brander, the Swedish Consul, who sent to 

 Linnaeus all his Algerian insects, could not go much beyond the limits of the 

 town of Algiers, and therefore could never have been near the haunts of T. 

 nauna, the only other white butterfly with orange tifs found hi Algeria, i.e. 

 Biskra and interior of the Province of Oran, the word in the description de- 

 scribmg the underside of the hindwing ought to have told anyone but a wilfully 

 obtuse person that belia could only apply to the Euchloe. This word flavissime, 

 when translated mto English, reads intense yellow, and therefore could not 

 apply to the Teracolus, in which the underside of the hindwing in the spring 

 brood is dirty pink, and in the summer brood is white, huffish white, or dirty 

 pale buff, but never intense yellow. 



The series at Triiig principally exhibits variation in the width and presence 

 or absence of the black borders to the orange apex of the forewuigs. 1 S and 

 1 ? from Guelt-es-Stel have the apices of the forewings almost completely black 

 and 1 ? from there has the orange patch as big as in the rjj, but without the 

 black borders as in the 5$, of b. androgyne Leech. The Tring series numbers 

 757. The S from Blidah (Faroult, 1916) is pale lemon-yellow, and the orange 

 of the apices is replaced by very pale pmk.
