unable to secure a furtlier leave of absence from the Italian gov- 

 ernment to make a further search for parasites in West Africa, 

 especially the ones he failed to introduce alive on his first expedi- 

 tion, arrangements were made with Mr. Fullaway of the Hawaii 

 Experiment Station to undertake the expedition under the aus- 

 pices and direction of the Board of Agriculture and Forestry, 

 Mr. Bridwell being delegated to accompany him as his assistant. 

 During the absence of these two gentlemen the writer took direct 

 supervision of the parasite breeding in the insectary so as to keep 

 alive all species on hand until Mr. Fullaway's return, which was 

 on October 27, 1914. A full account of the second expedition, 

 including breeding, recovery and distribution on the several 

 Island by districts of all the various parasites collected during 

 the biennial period, is attached hereto as a special report by Mr. 

 Fullaway, who has had charge of this work since his return from 

 Africa. The account of the first expedition by Prof. Silvestri will 

 be found in Bulletin I^o. 3 of this Division, as previously stated. 

 By a special arrangement made between the President of the 

 Board of Agriculture and Forestry and Dr. E. A. Back, special 

 agent of the U. S. Bureau of Entomology, I am also able to 

 append hereto a report by him and Mr. C. E. Pemberton, his 

 assistant, giving the percentage of parasitism and other observa- 

 tions obtained while carrying on other investigations for the U. S. 

 Government from materials collected in the field. 



There have been the usual inquiries regarding pests attacking 

 plants and it has been possible in a small measure for the Super- 

 intendent to give advice for the control of some of these whenever 

 a request came to hand. He has also been able to visit a few 

 localities and examine into damage done to crops by certain pests. 

 Appended hereto is a report on those insects which have more or 

 less given trouble during this period and such remedies which 

 have been successfully used in their abatement. 



STAFF. 



Your Superintendent has continued as head of the Division 

 during this biennial period, having as assistant inspector Mr. D. 

 B. Kuhns, and as assistants on the w^iarves Messrs. Edward Drew, 

 Robert W. Kanakanui and Isaac Kahere. On June 3, 1913, Mr. 

 J. C. Bridwell was appointed assistant superintendent of ento- 

 mology. On account of the unexpected arrival of Prof F. Silves- 

 tri with parasites from Africa, and finding it difiicult to obtain a 

 qualified man for parasite work here, as previously stated he was 

 detailed for that work by direction of the Executive Officer. The 

 services of Mr. D. T. Fullaway, entomologist of the Hawaii 

 Experiment Station, were upon request also loaned to the Board 

 for similar work, and the latter remained in charge of it until
