Dr. G. B. Longstaff's Bionomic Notes on Butterjiics. C27 



§ 4. Butterjlies hearing marks of tlic aUaclcs of foes. 



This very interesting bionomic point we owe almost 

 entirely to Prof. E. B. Poulton, F.R.S., and Mr. Guy A. K. 

 Marshall.* A list of the butterflies presumably injured 

 by enemies noted by me in India comprised 31 specimens 

 of 28 species.f I append further lists, which amply prove 

 Prof Poulton's statement that such specimens only want 

 looking for. In nearly every case the injury is symmetrical, 

 i. c. affecting the corresponding parts of both right and 

 left wings, so that the probability of the injury being the 

 result of damage during flight by branches or thorns is 

 very small.
