dant at Kelvin Grove and all along the Ithaca Creek 
branches of Enoggera Creek. Later on at Gympie, in 
1870, it was equally plentiful, and on my first visit to 
the Isis it was scarcely possible for anybody not to (notice 
their numbers. The introduced camphor laurel was not 
then grown at any of these districts. On the North Quay, 
Brisbane, it was quite frequently to be seen settling on 
the lantana blossoms, where this plant spread from the 
Botanic Gardens, and thence over all South Queensland, 
being carried chiefly by birds, which passed the seeds in 
a fit state for germination. 
The butterfly larva certainly did not feed on the lan- 
tana leaves, though the butterfly itself sucked the juices 
(nectar) from the flowers. Many butterflies will fly down 
on to roads and- tracks to imbibe filth from mud, ordure, 
etc., and this species is not exempt. Others again will get 
quite intoxicated from the fermenting sap of trees, also 
fallen fruits. 
In Japan the food plant is *Machilus thunbergii, and 
there it is abundant from April throughout their summer. 
Papilio eurypylus lycaon, Westwood. 
This handsome butterfly is equally as abundant and 
has almost the same range 1 of distribution as P. sarpedon, 
though it does not, as in that species, reach Japan. The 
upper surface of the wings is variegated by bands and 
spots of pale blue on a dark ground. The under parts 
are shining silvery blue relieved by red spots or lines on 
the hind wings. The larvae feed on various anonaceous 
plants, and have largely taken to the introduced custard 
apple. As in P. sarpedon they need the bright sun and 
an active life to attain full beauty of colouration, so that 
breeding the larvae gives poor results, the butterflies so 
obtained having a sickly hue. Tt is not seen so commonly 
in our streets as Sarpedon, but any garden possessing a 
custard apple tree is sure to attract it freely. 
There is an ochreous-yellow form of this species occa- 
sionally to be seen here, probably an aberration or variety 
only. 
*Rhopalocera Nihonica, Pryer. 
Papilio, a butterfly; Sarpedon, son of Jupiter by Europa, 
the daughter of Agenor, assisted Troy against Greece; was 
finally slain after many valorous deeds. Choredon not known, 
possibly intended for Corvdon, name of a shepherd used m 
the pastoral poems of Virgil and Theocritus,
