532 PAPILIONID.F.. 
Staudinger states that he has typical maacki from North China . 
Graeser obtained larvae of both broods of P. maacki in Amurland. He 
states that they were found feeding on Phellodendron, and that some of the 
pupse of the summer brood remain in that state through the winter, and of 
the imagines resulting from these hibernated pupa;, one of the female 
examples measured 90 miUim.,but with all the other characters oi\?iX.raddei. 
Pryer gives as the larval food " jEgle sepiaria and other kinds of orange- 
trees." 
Distribution. Amurland, Japan, Corea, and N. China. 
Papilio dialis. (Plate XXXII. fig. 4, d .) 
Papilio dialis, Leech, Entomologist, xxvi., Supjjl. p. 104 (1893). 
Male. Closel}- resembles P. bianor, but there is no patch of silky hairs between the first median 
ner^Tile and the submedian nervure, aud the patches on the veins are composed of shorter 
hairs. The primaries are black, sprinkled with bronz3--groen scales, except on the venation 
and broad rays between the nervulcs. Secondaries black, thickly powdered with greenish 
scales, those on the costal half and on the tails being bluish, and those on other portions of 
the wing bronzy ; there is a broad annular mark at anal angle, a lunule in first median inter- 
space, and another in disooidal interspace — all these marks are red dashed with lilacine on 
their upper edges. Under surface of primaries pale grey, merging into white on the outer 
two-thirds of inner marginal area : all the nervules and streaks between them are broadly 
black, and there are four nerve-like black streaks in the discoidal cell : secondaries velvety 
black, sprinkled on the basal and abdominal areas and on the tails with metallic-green scales ; 
there is a series of seven red irregular-shaped lunules on the outer margin, the sixth is united 
with the seventh by a broad projection from the lower edge of the latter, and its upper 
extremity almost unites with the lower end of the fifth lunule. 
Expanse 130 millim. 
One example taken at Chia-ting-fu in July. 
This species is most readily distinguished from P. Manor, P. maacki, &c., 
by the different arrangement of the silky sexual brands on the primaries of the 
male. 
Papilio syfanius. (Plate XXXII. fig. 5, 6 var.) 
Papilio syfanius, Obertliiir, Etud. d'Eat. xi. p. 13, pi. i. fig. 3 (188G). 
" La Papilio syfanius a ete decouvert a Ta-Tsien-Lou, par Mgr. Felix Biet. Je ne connais encore 
que le male. II est voisin de bianor et de dehaanii dont il differe par la forme plus retrecie 
de ses ailes inferieures, par I'abseuce de toute tache bleuatre vers la partie superieure de ses 
ailes inferieures en dessus, par le manque de toute e'claircie blanchatre le long du bord exte- 
rieur de ses ailes superieures en dessous, par la presence au contraire d'une eclaircie
