 by an entomologist was decided upon by the Board. 



KOHALA, HAWAII. 



I 

 On May 16, 1905, I sailed for Mahukona, Hawaii. Through 



the courtesy of Dr. B. D. Bond, I was domiciled at his house 

 as long as I remained in this district. The "coffee scale" 

 {Pulvinaria psidii, Mask.) was found there very abundant on 

 the under side of leaves of birdnest ferns, but most of 

 them were pierced by as many as four or five holes, the work 

 of two internal parasites, {Microterys ffavits, How., and an 

 undetermined sp.), both of which were observed in active 

 operation. A study of the mango fruit was made but no in- 

 sects were found affecting the healthy fruit. The mango 

 flower and fruit disease was in ample evidence. So was also 

 the ubiquitous Avocado pear scale {Pseudococcus nipae, Mask.). 

 Practically all of the insect pests observed here were of a na 

 ture that could be easily controlled, but the owners of the af- 

 fected plants are generally too busy with othjer things, so that 

 the plants and insects are practically abandoned to fight their 

 own battles. 



One morning was spent in company of Dr. Bond in his for- 

 est composed principally of Eucalyptus and Black Wattle 

 trees. The latter were evidently suffering from injury by 

 Fuller's rose beetle or "Olinda bug" {Aramigus fulleri, Horn.), 

 of which there were groups of immense numbers clustered on 

 the under side of leaves and branches. In the afternoon a 

 visit was paid to one of the homesteads in the neighborhood, 

 but not much of a show was found in either the plant or ani- 

 mal life. 



LAHAINA, MAUI. 



Taking the return "Kinau" I landed at Lahaina, where 

 among others, the Lahainaluna School and the premises of the 

 Homers' were visited. At the latter place it was delightful 

 to find a good lime orchard in excellent condition. The care 

 of this orchard is supervised by Mrs. Decoto, who told me that 

 the orchard has always yielded profit despite the presence of
