PAPILIONINjE. 
The nuchal horn of the larva is greenish-yellow, and is shown protruded in the figure of 
the fullgrown larva. 
Papilio sarpedon, Linn . 
A common and very beautiful species, with an exceedingly swift, wild flight, and though 
very fond of flowers it spends but a moment at each blossom, rapidly quivering its wings whilst 
feeding. Unfortunately the lovely greeny-blue of the wings is fugitive, turning green or yellow 
with age. Owing to its wild flight and habit of threading through jungle it is not often to be 
secured in good condition, and is usually very ragged. Like several other PapilionincB this insect 
often takes up a special beat, generally rather high up about the tops of trees, where it flies up and 
down, chasing away butterflies and other insects which encroach on its domain. 
Fig. 5, PL XIII is from a $ taken in May, but the sexes are very similar. The £, 
however, has a fringe of long white, silky hairs on the upperside of the abdominal margin of the 
hindwing, usually concealed by the natural fold of the wing, which is turned down over the hairs. 
In both sexes the broad blue band (white on the costal margin) down the hindwing is often broken 
up into separate spots, sometimes very small, or almost obsolete. This butterfly varies much in 
dimensions. 
Both larva and pupa are very much like those of P. eurypilus. The larva feeds on the 
orange tribe and on Laurus camphora. 
Papilio eurypilus, Linn . 
Not by any means a common insect near Macao, more plentiful at Hongkong. It has 
not quite so swift a flight as other butterflies of this group, and it feeds rather more leisurely at 
flowers. It is also known as P. telephus , Felder. The sexes are alike, but the $ has a fringe of 
white hairs on the hindwing, as in the $ of P. sarpedon . 
Fig. 4, PI. XIII is from a $ taken in September. 
Egg, globular, smooth, yellowish. 
Larva, just hatched, dark brown and yellowish, a pair of small processes on the second, 
third and fourth segments, and a rather larger pair on the last segment. A few days after hatching 
the larva becomes wholly dark brown on the upper surface, the processes, except those on the 
second and last segs., gradually becoming obsolete, as is usual with many Papilio larvae. 
Whilst still young, upper surface dark brown, two small brown processes on the second seg., 
two small yellowish processes on the last seg. An indistinct lateral whitish line just above the
