328 _ THE SPHINGID OF SINGAPORE. 
C. nessus. 
Calymnia panopus. 
And two or three cther species probably new. 
SUB-FAMILY.—VWacroglossine (Humming birds). 
Hlemarts hylas. 
M. luteata. 
M. insipida. 
The convolvulus hawk (Sphinx convolvuli) is the com- 
monest. It may be taken at almost any season, but is more 
plentiful at some times than at others. 
This moth may almost always be taken at honeysuckles 
and when faradaya papuana is in flower one may be sure of 
obtaining large numbers at it. In fact they are so fond of it 
that I have taken as many as three at a single stroke of the 
net, and fifteen or twenty in one night is not an exceptional 
take. The caterpillar feeds on the Tembusu tree. 
Diludia discistriga closely resembles the foregoing species 
in general appearance and habits, but is larger, darker and 
has no red on its body and does not fly quite so rapidly. It 
is not nearly so common as S. convolvult. In fact, except at 
certain limited times, it is rare. 
Next come the death’s heads (Acherontiinz) represented 
by two species. These are large handsome moths whose 
principal colouring consists of black and yellow. They are 
usually taken at light. I have not yet heard of their being 
taken at flowers. 
By far the largest proportion of the species recorded from 
Singapore are comprised in the sub-family Choerocampinez. 
The largest and one of the finest of this sub-family is 
Calymnia panopus, the female of which is over 6” in span. 
Another beautiful member of this family is Cherocampa nes- 
sus, one of the handsomest hawks, its beautiful form and 
splendid green and golden orange tints rendering it conspi- 
cuous. The fore wings, dark green at the costal edge, shade 
off into the softest of browns, fawn and grey; the hind wings 
being deep glossy black contrasted with pale fawn. The 
abdomen is green down the centre of the back with a broad 
golden stripe down each side. The underside of the wings is
