the "purple scale" and other citrus pests. It appears that Mr. 

 Koebele stopped at the house some time ago and at his sug- 

 gestion the lady secured a spraying outfit which she has em- 

 ploj^ed to good advantage. The trees looked well trimmed 

 and the soil between them in good state of cultivation. This 

 was an excellent demonstration of what could be accomplished 

 in citrus culture on these Islands when intelligence is applied. 



WAILUKir, MAUI. 



That very day I took stage for Wailuku and the following 

 day was profitably invested interviewing persons taking promi- 

 nent interest in matters agricultural and in studying the in- 

 sect problems of the place. The most striking feature to an 

 entomologist about Wailuku is the blackness of the lantana. 

 This is due to the presence of the lantana scale insect 

 (Orthezia insignis, Dougl.) which was first observed there. It 

 was interesting to note that the lantana in the vicinity of where 

 the scale bug was first discovered is alive at present, although 

 blackened and injured. Moreover, as noted on another page, 

 here was my first experience on these Islands to find lantana 

 scale in injurious numbers upon a plant other than lantana. 

 Otherwise the insects affecting plants commonly cultivated on 

 these Islands did not much differ from those we are accus- 

 tomed to see in and about Honolulu. 



KAHULUT AND PUUNENE, MAUI. 



The following morning I took train for Kahului where I 

 had the pleasure of meeting Mr. Filler, who informed me that 

 to his knowledge and belief no fruits or plants entered the 

 port of Kahului without a previous inspection by the entomo- 

 logist in Honolulu. The courtesy of a visit to Puunene, which 

 I had the pleasure of making in the company of the Hon. H. 

 P. Baldwin, was extended to me. There I was greeted by an 

 interesting entomological problem. The Casuarina shade trees 

 lining the streets and all the citrus trees upon the premises 

 were dying from the effects of "cottony cushion scale" 

 {Icerya purchasi, I\Iask.), with which they Avere thickly in 

 fested. This, notwithstanding the fact that only two or three
