PROTECTIVE MIMICRY (932-46) 
Collection prepared and mounted by the Denton Bros., Welles- 
ley Mass. 
932 Danais tytiaGray (India). This insect is protected 
from the birds by an unpleasant odor or taste, and it is mimicked 
by 933, which is not distasteful to birds. 
9838 Papilio agestor Gray (India). This insect departs 
widely from the general appearance of most of its close rela- 
tives. Its resemblance to 932 undoubtedly protects it from 
molestation by birds. 
934 Hebomoia glaucippe Minn. (China). Under sur- 
face; note its resemblance to the skeleton of a leaf. 
935 Hypolimnas misippus Linn. (India). The female 
- mimics 937, which is protected from birds by an unpleasant odor 
or taste. Compare with the male, 939. 
936 Erebomorpha _ gp. (India). Note light and shadow 
effect, which is probably protective.
