of the insect, which continued to emit it for some minutes, with redoubled 
vigour when touched. Amesia namouna^ also, has something of a resemblance to 
the genus Euploea^ but its habits would seem to differ from those of the butter- 
flies, though it is very possible that the substance secreted by it may have a 
physiological relationship to the well-known noxious juice of this family of 
Rhopalocera.’

‘ Several other very much injured specimens were brought us by natives 
at Sai Kau. The specimen preserved was taken resting under the leaf of a 
tree, which grew just at the edge of primaeval jungle. The head of the moth 
was bent down below the level of the thorax, the antennae were quite con- 
cealed beneath the fore wings, which were folded and arched so as to make 
the dorsal surface rounded, and the first pair of legs were held stretched out 
in such a way as to resemble those of a beetle. I mistook the specimen, 
which made no attempt to escape, for some large Buprestid, and was surprised 
to find it soft to the touch. We did not capture any species of beetle to 
which this moth could be said to bear a definite resemblance ; but Buprestids 
with a similar type of coloration (forepart of the body dark metallic green, 
wings or elytra, flame-colour or deep orange, boldly spotted with the same 
metallic shade) occur in the Malay Peninsula, and Mr. Richard Evans, of 
the Skeat Expedition, found on Bukit Besar a Longicorn — not yet described, 
but probably belonging to a new genus — which presents very much the same 
general appearance, though in shape it does not resemble the moth so closely 
as certain of the Buprestidae would do.’
