PROTECTIVE MIMICRY (932-46) 



Collection prepared and mounted by the Denton Bros., Welles- 

 ley Mass. 



932 D a n a i s t y t i a Gray (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. 



933Papilio agestor Gray (India). This insect departs 

 widely from the general appearance of most of its close rela- 

 tives. Its resemblance to 932 und(>ubl<'dly protects it from 

 molestation by birds. 



934 H e b o m o i a g 1 a u c i p p e Linn. (China). Under sur- 

 face; note its resemblance to the skeleton of a leaf. 



935 H y p o 1 i m n as in i s i p p u s Linn. (India). The female 

 mimics 937, which is protected from birds by an unpleasant odor 

 or taste. Compare with the male, 939. 



936 E r e b o m o r p h a sp. (India). Note light and shadow 

 effect, which is probably protective.
