While colU'ctiug insects at Kilauea in company with Oommissioner 

 (liffard it was discovered that the Australian weevil, Syagrius fulvitarsis, 

 is infesting the ferns of the forests at 29 Miles. Although, the weevil 

 has been known in Hilo for a number of years, it was never before 

 observed outside of green-houses on Hawaii. A thorough survey was 

 made at once and it was determined that the infestation was continuous 

 and confined to a rather small area. In view of this fact and the great 

 danger to the forests in case the infestation should spread^ steps were 

 taken to eradicate the insect in the circumscribed area by cutting and 

 burning its food plant and going over the ground thoroughly witli a 

 torch flame to destroy the adult beetle. It is a fortunate circumstance 

 that the weevil does not fly and is dependent on one or two of the 

 ferns in the native forests. It will be necessary however to maintain 

 a very close inspection of the area to prevent further spread.
