This is the well-known Black Coconut-beetle or Khinoceros Beetle, one of 

 the two conunon pests of the Coconut-Palm throughout the East. The insects 

 tunnel into the soft wood at the growing point of the tree, and are said to 

 deposit their eggs there. The larvae feed upon any decomposing vegetable matter.

 from India or Ceylon in fairly recent times.
