PAPILIO. By Dr. IC. Jordan. 
hindwing less extended grey-white than in medon. The under surface darker, the forewing as in the races 
from the Philippines, Talaut, Celebes and the Sulla Islands with large grey spot at the apex of the cell and grey 
band in the middle of the cell, hindwing basally grey, with narrow grey discal band, all these grey mark¬ 
ings weakly developed. Solomon Islands, known to me from: Bougainville, Shortland, Choiseul, Maleita, 
christobalus. Florida, Guadalcanal'. — christobalus subsp. nov. paler than pisidice, especially on the under surface; 
the band broader; the white marginal spots of both wings much more extended. Beneath the grey cell-patches 
of the forewing and the grey discal band of the hindwing more strongly developed, the band of the forewing 
from the 7 th spot twice as broad as in pisidice. San Christoval, May 1908 (A. S. Meek), 1 $ in the Tring 
tenebrionis. Museum. — tenebrionis Ftothsch. (43 a). The band of the forewing only reaches the 1 st median, as the posterior 
3 spots are absent; the hindwing is much less extended grey-white than in pisidice. In some specimens the 
forewing has a very small green spot at the proximal side of the 1 st patch. New Georgia, Bendova, Vella 
Lavella; probably on all the islands of this western group of the Solomons. 
Eurypylus-Group. 
The 1 st subcostal of the forewing runs into the costal, the 2 nd subcostal is free or likewise joins the 
costal. Body above dark with a light stripe at each side. The wings for the most part black, above with 
green (or yellowish) markings, which are scaleless. Under surface of the hindwing with red or yellow discal spots 
from the apex of the cell to the anal angle or at least traces of such spots, and usually one or two red or 
yellow subbasal spots, which are never absent even when the red discal spots are suppressed. The tail when 
present short and obtuse. — Some of the species are extraordinarily common. Freshly emerged examples and 
those killed too soon have the markings whitish or yellowish instead of green; decayed as well as worn specimens 
are likewise yellowish. Such individuals therefore do not represent aberrations, yet fresh specimens are also 
taken with yellowish markings. The normally red spots on the under surface of the hinclwing are replaced in 
single individuals by yellow ones, which may happen in all the species. 
P. cloanthus. Body black, head and thorax above with grey-greenish hairs, beneath grey, abdomen 
beneath yellowish white with two black lines, above with yellowish white lateral lines. Wings above black, 
forewing with two large cell-patches and a broad discal band, which is continued on the hindwing in the form 
of a triangle, hindwing in addition with 4 submarginal patches, all these markings green, transparent, the bands 
and patches of the forewing as well as the submarginal spots of the hindwing above scaleless. The dark areas 
beneath somewhat paler than above; the hindwing with red line at the base and small red linear spots from the 
end of the cell to the anal angle, only the last spot somewhat larger. The $ similar to the <$. Larva green, 
beneath bluish, on the 4 th segment a laterally projecting yellow transverse band, at each side of the back a yel¬ 
lowish longitudinal line. On Machilus odoratissima. Pupa bright green, with yellow carinae. The butterfly 
occurs throughout the summer; the spring specimens of North India and China differ from the summer specimens 
in the enlarged green markings. The butterfly has a very rapid flight and is fond of remaining high up among 
the tops of trees, round which it flies with a dancing motion. The drinks on wet sand, keeping the wings 
closed. From Kashmir to the Shan States, China, Formosa, Sumatra; not yet known from Tonkin, Siam 
clymenus. and the Malay Peninsula. — clymenus Leech (vol. I, 8 c), from Central and West China, certainly occurs also 
in the mountains of South China. The spring form resembles the North Indian summer form, whilst the summer 
form of clymenus is more extended black. In the Tring Museum there is a single specimen from Formosa, which 
is distinguished from the spring form of clymenus by somewhat broader wings and broader submarginal line 
cloanthus. on the under surface of the forewing. — cloanthus Westw. The median vein of the forewing is never entirely 
black in the green parts of the wing, likewise the two median veins are at most black distally in the grey area. 
In the smaller spring form, f. vern. cloanthus Westw., the green areas are large. In the somewhat larger summer 
cloanthulus. form, which has received the unhappily chosen name of f. aest. cloanthulus Fruhst., the wings are more extended 
sumatrana. black. Distributed from Kashmir to the Shan States. — sumatrana Hag. (45 b). A strikingly different form. 
Yellow-green, the dark parts of the under surface purple-brown, dusted with reddish grey. In the mountains 
of Sumatra, the $ rare. 
P. sarpedon. Body above brownish black with brown-grey hairs, beneath for the most part white- 
grey. Wings above brownish black, with green or green-blue discal band, which is strongly narrowed towards 
the apex and separated into spots and posteriorly on the hindwing is produced into a point; the costal part of 
the band on the hindwing white-scaled, as also partly the veins intersecting the band; the cell of the fore¬ 
wing nearly always without markings, but occasionally a row of submarginal spots is present; hindwing 
triangular, with green or blue submarginal lunules. Under surface paler than upper, the discal band scaled 
with transparent whitish, hence with slight mother-of-pearl gloss; forewing at least with slight indications of 
submarginal spots before the hinder angle; hindwing near the base with red transverse bar, which extends 
from the costal margin to the cell and is separated from the discal band; 5 red discal spots, of which the an-
