 cane field is almost in every case indicative of the presence of

The larv« being one inch long and in form very similar 

 to the palm worm, are very voracious and will perforate and make 

 large cavities in the cane which soon brings about the total 

 collapse and decay of the plant. 



When the larA'a is ready to effect its transformation, it envelops 

 itself in a sort of shrotxd of fibres, mixed up with its excreta and 

 other decayed matter glued together tightly ; there it passes its 

 chrysalis stage and in 18 to 20 days becomes the perfect insect.
