or a dirty white. I have seen more than a dozen of these 
grubs taken out of one cocoanut tree. The loss which 
a cocoanut farmer suffers from the attacks of these 
insects is often very serious. In order to get rid 
of them, branches and bunches of unripe cocoanuts have 
often to be torn off, the trees are generally weakened 
by their depredations, and if they are not dealt with in 
time the inse6t eats into the heart of them and kills them. 
Lamp oil, fine salt, and lime are often used to drive and 
keep them away. When about to enter the chrysalis 
state they weave for themselves neat oval cocoons with 
stripes torn from the stem of the cocoanut tree. This 
grub is known as the Gru-gru worm, and is said to be 
eaten alive by the natives like an oyster, but, though I 
have heard and read of this, and it may be quite true, I 
have never seen any body eat one. They evidently 
attack other palms besides the cocoanut. I have seen 
the beetles assemble in numbers when a mountain cab- 
bage tree was felled, and I understand they attack the 
sugar-cane. 
The Rhina barbicornis or Bearded-beaked Weevil 
belongs to the same family as the insect described above. 
It is readily distinguished by its hairy snout and long 
slender legs. When looked at with the naked eye this 
insect appears to be striated and speckled, but I under- 
stand when viewed through a microscope it is found to be 
richly decorated. It is smaller than the Palm Weevil, 
but varies very much in size. I have not seen this inse6t 
in Wakenaam or Leguan, but have met with it in 
Fort Island. 
The Calandra saccharia, Sugar Weevil, or Cane 
Borer also belongs to this family. It is a comparatively
