THE SPHINGIDZ: OF SINGAPORE. 329 
a beautiful combination of reds, yellows and greys, which 
a'most rivals the autumn tints of the birch. 
Then we have the beautiful Ce/erzo, distinguished by its 
rows of silver spots down each side of the body. It is com- 
mon on Sarleria flava and Vinca rosea (Madagascar peri 
winkle). 
Isoples Rafflestt and /. Theylia resemble one another in 
general appearance, but 7heylza is smaller and paler. These 
are common on Larleria and Vinca. 
Pergesa acteus, more commonly known as the green 
elephant, is a beautiful insect. Its fore-wings are of a dark 
greencolour. It is found on the same flowers as 7hev/ia and 
Celerto. ' 
Of the Macroglossine the most remarkable is Hemaris 
hylas, which frequents the coffee plantations, the larve feed- 
ing on the coffee tree, where it often does much damage. 
It has also been taken on lantana. The chief peculiarity 
of this moth is in its wings, which are quite transparent like 
those of a bee. 
The other humming birds are most plentiful at lantana and 
the tembusu (fagrea peregrina) when in flower. The male 
flowers of the papaw are alsoa great attraction. The mem- 
bers of this sub-family do not remain out after dark. 
There is much yet to be found out as to the form and 
habits of the larve and pupe of these moths, and there are 
probably new species to be found and described, so that there 
is ample scope, for any one taking up the subject to add to 
what is already known.
