The X after the collector's name denotes that one or more specimens belong 

 to the ? forma helice. I have never seen nor do I possess a single Jlauretanian 

 example of the § forma helicina Oberth. ( = intermediate ? form between helice 

 and normal ?), and considering the large series I have from jVIauretania, the 

 number of pale yellow SS (3) is very small. 



The British Museum has the following specimens from Mauretania : 7 

 Meade- Waldo ; 2 Tangier and 2 Mogador, January 1881, Leech coll. ; 2 Biskra, 

 May 1882, H. J. Elwes ; 2 Philippeville, May 1882, H. J. Elwes. 



Mr. Meade- Waldo in his article quotes Tangier, December — January ; 

 Interior, May — June. The Tring series from Mauretania consists of 243 speci- 

 mens. 



23. Gonepteryx rhamni meridionalis Rober. 



Gonepteryx rhamni meridionalis Rober in Stitz Grossschmett. der Erde, vol. i. p. 67 (1907) (Algeria 

 and S. Asia Minor). 



Mr. Charles Oberthiir states that two subspecies of this insect occur in 

 Algeria, the large meridionalis and a small form indistinguishable from typical 

 rJiamni, and he records two such small specimens m his collection taken at Alger 

 by the late Lieutenant Mathieu. Now Gonepteryx rhamni is very rare indeed 

 in Algeria, and almost as rare in Tunisia and Morocco, so, as Mr. Oberthiir truly 

 remarks, we require much fuller material before deciding finally on this question; 

 but I would like to pouit out that rhamni meridionalis could under any circum- 

 stance only be treated as a subspecies or local race, and we frequently find that 

 among such local races individuals appear sporadically which are indistinguish- 

 able from the type, although 75 per cent, or more of the individuals exhibit all 

 the distinguishing characters of the local race. This being the case, I do not 

 consider these small Algerian rham,ni, of which I have two from Batna, at all 

 invalidate the subspecific value of the race rhamni meridionalis. South Portu- 

 guese specimens (Monchique, Dr. K. Jordan) are not meridionalis.

24. Gonepteryx cleopatra (Linn.). 



Papilio cieopalra Linnaeus, Syst. Nat. edit. xii. vol. i. part 2. p. 765. No. 105 (1767) (Barbaria). 



It is very curious, as Mr. Oberthiir remarks, what a comparatively large 

 number of gynandromorphous specimens occur in this species ; of the three
