44. Papilio palinurus, Fabricius. 



Better known to Indian collectors as P. hrama, Guerin. Widely 

 distributed in Burma, but is always rare. Mr. Hauxwell notes : " The 

 butterfly has the habit of bathing in shallow water in hill streams. It 

 akims over the surface of the water like a swallow, and dips its body 

 into the water, giving itself a shake as it comos out and then flies on 

 again." Amongst moths, many of the Sphingidce in India have a 

 similar habit.
