end of the summer, and that the laiTa feeds onjEglescjiiaria. According to 
de 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 Niugpo ; the only Chinese locality from which I 
have received specimens is Kiukiang. 
There is very little to separate P. demetrius from P. jyrotenor, excepting 
that the latter is without tails — a character which in some species of Papilio 
is of but little importance. 
Distribution. Japan ; Central and Eastern China. 
Papilio macilentus. 
Papilio macilentus, Jansoii, Cist. Eutom. ii. p. 158 (1877); Pryer, Rhop. Nihon. p. 4, 
pi. iii. fig. 2 (1886). 
Papilio sccBvola, Oberthiir, Etud. d'Eutom. 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 
duU 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 scr^vdla, Oberthiir. — " Eemplace quelque part le demetrius du Japon ; differe de celui-ci 
par une taille plus petite et la forme de ses ailes inferieures fortement dente'es, etroites, 
allongees, avec la queue longue et paraissant pen reeourbee interieurement." (Oberthur, I.e.) 
Papilio traetipennis, 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 
fascicle, 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 (neo 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 thu 
nale, and the tails are shorter. Expanse of wings 5 inches. Nikko." {Butler, I. e.) 
I have specimens from the Island of Kiushiu. According to Pryer this
