end of the summer, and that the larva feeds on JEgJe sepiaria. According to 

 do rOrza the larva is found on orange-trees. 



Mr. Elwes, referring to this species (Proc. Zool. Soc. Lond. 1881, p, 872), 

 remarks that he and Mr. Godman possess specimens taken by W. B. Pryer in 

 the Fungwhan Hills, near Ningpo ; the only Chinese locality from which I 

 have received specimens is Kiukiang. 



There is very little to separate P. demetrius from P. jprotenor, excepting 

 that the latter is without tails — a character Avhich in some species of Papilio 

 is of but little importance. 



Distribution. Japan ; Central and Eastern China. 



Papilio macilentus. 



PapUio macilentus, Janson, Cist. Entom. ii. p. 158 (1877); Pryer, Rhop. Nihon. p. 4, 



pi. iii. fig. 2 (1886). 

 Papilio scavola, Oberthiir, Etud. d'Entom. iv. p. 37, pi. vi. fig. 1 (1879). 

 Papilio tractipennis, Butler, Ann. & Mag. Nat. Hist. (5) vii. p. 139 (1881). 



" Allied to P. demetrius, Cram., but with all the wings narrower and much more elongated ; pri- 

 maries above dusky black, the black streaks between the nervures very narrow ; secondaries 

 with the outer margin strongly notched, the tails long and narrow, black, costa pale yellow, 

 four small indistinct spots along the outer margin, and a broad ring on the abdominal margin 

 dull red ; beneath the primaries are paler than in demetrius and somewhat shining ; secondaries 

 with four lunular spots along the outer margin, an interrupted ring on the abdominal margin, 

 and a spot near the anal angle pale red. Expanse of wings 3|-4| lines. 



" The very long slender wings are sufficient to distinguish this species at once from P. demetrius. 

 Cram., the only species which resembles it in other respects ; it appears to be confined to the 

 mountains, and has been taken by Messrs. Pryer and Jonas on Oyama." {Janson, I. c.) 



Papilio sc'vvola, Oberthiir. — " Eemplace quelque part le demetrius du Japon ; difJere de celui-ci 

 par une faille plus petite et la forme de ses ailes inferieures fortemeht dentees, etroites, 

 allongees, avec la queue longue et paraissant peu recourbee interieurement." (Oberthiir, I.e.) 



Papilio tractipennis, Butler. — " Male. Intermediate in size between P. macilentus and P. demetrius ; 

 similar to the latter, from which it differs in its greater size, its more elongated wings, longer 

 and broader tails, also in the greyer tints of the primaries, upon which the black outer border 

 appears more prominently ; below the primaries are distinctly paler and greyer, the markings 

 upon the secondaries are brighter in colour, redder, and there is an abbreviated additional red 

 fasci61e, bounded below by an arcuate streak of blue scales, across the first median interspace. 

 Expanse of wings 5 inches 2 lines. 



" Female. This is the P. demetrius of Gray (nee Cramer) ; but when fresh this sex is nearly as dark 

 as the male, although browner in tint, and with two ocellated and several submarginal lunate 

 red markings on the upper surface of the secondaries ; as usual, it is broader in wing than tho 

 nale, and the tails are shorter. Expanse of wings 5 inches. Nikko." {Butler, I. c.) 



I have specimens from the Island of Kiushiu. According to Pryer this
