EXTRACTS FROM CORRESPONDENCE. 



The Icerya in Honolulu. 



Yours of the 18th instant in regard to the Icerya at Honolulu is received. Some- 

 thing over 3 years ago I sent a letter of inquiry and inclosed specimens of the 

 Icerya and Red Scale to Mr. Irwin, of Honolulu, but heard nothing from it until the 

 past summer, when I received a letter from Mr. A. Jaeger, to whom my letter of in- 

 quiry had been shown. Among other things Mr. Jaeger writes me under date of May 

 17, 1890, as follows: 



* * * " The rest of them (scales) have made their appearance, one after the other, 

 and last but not least, the cottony scale, about 9 months or perhaps a year ago. 

 When in September last my attention was first called to this new insect I had no idea 

 of its destructiveness. As a matter of fact we have this curse on fifty or more prem- 

 ises (gardens) in the neighborhood of Honolulu, and if we do not make great efforts 

 to destroy the same our gardens and perhaps the whole country may be ruined." 

 Before writing to me Mr. Jaeger had sent specimens of the pest to Dr. H. W. Hark- 

 ness, the President of the California Academy of Sciences, and Dr. Harkuess pro- 

 nounced it the genuine Icerya purchasi, and advised Mr. Jaeger to write to me for 

 some of the Yedalias. President Kercheval, of our county board of horticulture, 

 and Inspector Weis, of this city, collected a colony of the Vedalias and I put them up 

 for shipment to Honolulu, where they arrived in good condition and were colonized 

 upon the Icerya infested trees and plants. 



This is all the information that I possess upon this subject, but will make further 

 inquiries, and apprise you of the result. — [D. W. Coquillett, Los Angeles, Cal., Nov. 



24. 1890. 



Mr. Jaeger's answer to inquiries just mentioned. — Your letter of November 



25, has duly come to hand, and I am glad to be able to answer your questions. 



1. Locality xchere the Icerya icas found. — Seaboard of Honolulu, including Waiki and 

 Kalihi, distance about 7 miles, the whole stretch being say from 2 to 4 miles in width. 

 No reports have been received from other districts or from any of the other Islands. 



2. First introduction. — Spring or summer of 1889; first specimens seen by myself and 

 others in September ; looked upon them as curiosities. In April, 1890, however, awoke 

 to a sense of danger. At a meeting held during the month a gentleman asserted that 

 he had not planted a new tree or shrub on his premises for years, and still they were
