the insects occiiring in the Territoiy in order to be posted on 

 our enemies and friends. Frequently we are also called upou 

 to determine the identity of an insect upon plants undergoing 

 inspection. Great accuracy is a requisite of this work, since 

 of two closely allied species of insects one may be already es- 

 tablished on these Islands, and the other not yet, and, depend- 

 ing upon which of these infests the plant under investigation, 

 the consignment is either admitted after fumigation or de- 

 stroyed. So far as possible identifications were made in the 

 office. With our equipment of laboratory, library and col- 

 lections, this was possible in the case of many insects, particu- 

 larly Coccidae. For assistance in naming insects in other 

 groups the thanks of the office are due to Messrs. R. C. L. Per- 

 kins and G. W. Kirkaldy, of the Hawaiian Sugar Planters' 

 Association Experiment Station ; to Dr. L. 0. Howard, Chief 

 of the U. S. Bureau of Entomology, and his assistants at 

 Washington; and to Dr. W. H. Ashmead and Mr. A. N. Caudell 

 of the U. S. National Museum. 



A number of species of Coccidae and Hymenopterous para- 

 sites, some of them new to science, were discovered in addition 

 to the published lists. As stated before, it is hoped soon to 

 publish a complete list of both these important groups. As 

 related in a report to the Board, printed below, one very dan- 

 gerous scale insect was discovered on Hawaii and it is be- 

 lieved, eradicated. 



* AERANGEMENT OF COLLECTIONS. 



As pointed out in last year's report this work is absolutely 

 necessary in an entomological laboratory. As scale insects 

 (Coccidae) are an important element in the economic insect 

 fauna of this Territory, a special case was provided for our 

 collection of these. A cabinet was also built to contain our 

 main collection of insects. AVhenever time permitted this 

 work was carried on. The collection is increasing as fast as 

 it could be taken care of and soon will be a fair representative 

 of our economic insect fauna.
