Islands by Albert Koebele, for the purpose of coping with Mealy Bugs, and other 
related Scale Insects there. ‘‘ When I visited Kona,” writes an independent witness, 
“of Hawaii, in 1892, many of the trees were literally festooned with hom isses of this 
pest (i.e., Pulvinaria), and appeared on the point of being totally destroyed. In 1894 
the Lady Birds were sent there, and yery soon had entirely changed the condition of 
things, and the affected trees speedily recovered. ‘T'o show the vast increase of this 
species of Lady Bird, I may state that in June of the present year (1896) many of the 
large trees in the city of Honolulu had several square feet of their bark entirely 
» hidden by the larve, which formed great white masses presenting an extraordinary 
appearance.* Its useful work in coping with the Mealy Bugs (Dactylopius vastator, 
Maskel, and D. Ceriferus, Newstead)—the former said to be the most pernicious 
coccid ever met with, have been recorded by Mr. Koebele himself. +
