 HUALALAI. 



At the invitation of the Forester, 11. S. Hosmer, who arrived 

 at North Kona about that time, I accompanied him up the 

 Kona slope of Hualalai to examine the insects affecting the 

 trees on the proposed forest reservation. It was rather wet 

 and cloudy most of the time spent up the mountain side. A 

 fair collection of native insects was made, but none of them 

 were found injurious to the prevailing vegetation. Nor were 

 any of the noble Koas met there affected in any way.

 known in Ceylon as "Green bug" (Coccus riridis. Green). 



This is the first time that the attention of any entomologist 

 was brought to the existence of this dangerous insect upon 

 these Islands. ]\Ir. Green, the Government Entomologist of 

 Ceylon, reports it as occurring there upon a large variety of 

 plants, including Citrus, Guava, Manihot (ceara and para) , 

 and last though not least important, upon coffee, both Liber- 

 ian and Arabian. In a recent monograph of the species of 

 this genus occurring in Ceylon, Mr. Green has the following to 

 say regarding this species : 



" 'Green bug' has proved such a scourge in Ceylon, being 

 practically responsible for the final abandomnent of coft'ee
