432 SPHINGLDiE. 



9. Edge of vaginal cavity not obviously raised to a ridge. 

 Hab. W. and E. Himalayas, S. India, Burma and Ceylon 

 to Japan, Malaya, Papuasia and Australia. We have bred it 

 in S. India and the E. Himalayas. It is a common species 

 in suitable localities, preferring hills and forest areas with 

 heavy rainfall to open dry country, though we have seen 

 some specimens collected at Aden.

 mandible strongly toothed ; eyes 1 to 4 forming a semicircle ; 

 6 in line with 3 and 4 ; 1 to 4 equidistant, 6 slightly further
