THE SPHINGIDA! OF SINGAPORE. 327 
ever, taken Diludia discistriga at Crinum asiaticum as late 
as 10 p.m. 
In the daytime they remain concealed amongst the foli- 
age of trees and bushes. They are sometimes taken at rest 
on the trunks of trees or in corners of rooms whither they have 
probably been attracted by the light in the evenings. They 
seem to be very sensitive to the state of the weather and the 
moon and on moonlight nights few are to be seen at the flower- 
beds. Fine evenings after rain are usually the most favourable 
for observing them. 
Like many other insects these moths are liable to be at- 
tacked by a species of internal fungus. 
Three at least of this family of moths—Acherontia medusa 
A. morta and Diludia discistriga—make a _ squeaking.
