On February 16, Laboratory Assistant Q. C. Chock was sent to 29 Miles, 

 Olaa, Hawaii, to look over the fern weevil situation and dust the infested area 

 with arsenate of lead to destroy the remaining weevils. 



He returned on February 20 and reported that he had found a few weevils 

 on ferns in a strip of land between the Cook lot and the Koa Reserve. The 

 infested area was dusted thoroughly with arsenate of lead and to prevent 

 any possible chance of the weevils spreading, a strip of land forty feet wide 

 surrounding the infested area was also dusted. Some time was spent in 

 examining the ferns adjoining the infested area but no weevils were found 

 on them. 



Respectfully submitted, 



E. M. EHRHORN, 



Acting Entomologist.
