the death of the whole plant. In 1909, it was found to have 
become established in a fern-house in Hilo on the Island of 
Hawaii. Attempts were made to eradicate it there, but later 
on it was found generally spread throughout the town, and by 
1920 had extended its spread to some distance outside. A con- 
siderable colony was found at a distance of twenty-nine miles 
and at an elevation of nearly four thousand feet, near the 
volcano Kilauea, where there are extensive tree-fern forests, in 
places chiefly composed of Sadleria, which were thus threat- 
ened with destruction as they had been in the mountains near 
Honolulu. Strenuous measures were employed by the Terrt- 
torial Board of Agriculture to eradicate the weevil in that 
place, with as good success as has ever been attained in the 
destruction of an insect pest that has once become thoroughly 
established.
