The four specimens in the Tring Museum from t!ie i.orth of the Province 

 of Oran are certainly unmistakable maxima, in fact, one of the Ma-ser Mines 

 specimens is as big as many summer specimens of machaon hifpocrates Feld. 

 from Japan (length of forewing 52 mm., expanse 109 mm.). 



Mr. Blachier (loc. cit.) records maxima from Marakesch, coll. Vaucher and 

 Tangier, from the same source. 



There are in the British Museum three specimens collected by Ms. Meade- 

 Waldo. In the Trans. Entom. Soc. Lond. 1905, pp. 369-392, Mi-. M-ade-Waldo 

 records Tangier January and August 1901 ; Amsmiz, June 1901 ; Imentalla, 

 1901 ; and Forest of Marmora, March 1902. 



3. Papilio machaon saharae Oberth. 



Papilio nuKhaon var. saharae Oberthur, Elud. d'Entom. iv. p. 68. sub No. 192 (1879) (Laghouat). 

 Papilio macJiaon var. hospifonides Oberthur, Elud. d'Enlim. xii. p. 21. t. 5. f. 19 (1888) (larva 

 Biskra). 



Ii] Novit. Zool. vol. XX. p. 109 (1913) I kept hospitonides separate from 

 saharae, as my Laghouat and Bou Saada imagines were somewhat different from 

 the desert specimens from elsewhere. Since then I have examined more 

 material, both larvae and imagines, and I find that though the imagines represent 

 two di; tinct types — viz. either very small with the yeUow much reduced or 

 somewliat larger with the submarginal yellow spots strongly developed and 

 with a curious yellow bloom over the whole insect, giving it a mealy appear- 

 ance — nevertheless all the desert machaon have the hospitonides form of larva 

 and so represent one local race only. Therefore the name saharae must be used 

 for this subspecies, it having nine years' priority over hospitonides. 



Of the Bou Saada series one specimen is very different from the othersi 

 beuig quite indistinguishable from North Algerian ones. It is, of course, well 

 known that occasional specimens of subspecies show greater resemblances to 

 other races of the same species than to the one to which they geographically 

 belong, but this specimen is too much like m. mauretanica. Victor Faroult has 

 the bad habit, which was equally the case with our lamented friend William 

 Doherty and our poor collector Heinrich Kiihn, of dragging about with him, 

 when travelling, odd specimens of lepidoptera captured on previous expeditions. 

 I therefore feel sure that this specimen in question was obtamed somewhere else 

 and included in the Bou Saada lot by mistake. The remaining 41 Bou Saada 

 specimens vary much in size, though all are small. The smallest has the length 

 of forewing 24 mm. and total expanse 52 mm., while largest has the forewing 

 40 mm. and a total expanse of 85 mm. The specimens at Tring total 65.
