months previous to that a strong colony of Vedalia (Xoviiis 

 cardinaUs) was released there. It was also noted that a Ca- 

 suarina within a yard where it had evidently received good 

 attention was practically free of the pest although the tree 

 across the way was dying. I was forced to conclude that the 

 prevailing drought was responsible for the state of affairs 

 and this conclusion was confirmed when I was informed that 

 in all probability owing to the drought no water was avail- 

 able for these shade trees. Of this incident you were informed 

 at the time, as I used my letters in place of a report, — in other 

 words, instead of noting down my observations and then copy 

 them into report form, I wrote them down in the letter to 

 you at the end of each convenient day. 



IVIAKAWAO, MAUI. 



By rail and hack I reached Makawao towards evening of the 

 same day. Mr. AV. 0. Aiken, the honorary entomological in- 

 spector of the Board, with whom I stayed part of the time 

 spent in Makawao, had been crippled by an accident and was, 

 therefore, not in a position to give me much information' on 

 the imports at Kahului. In company of Mr. Jas. Lindsay of 

 Haiku, I went up to Kailiili, where the day was very profitably 

 spent with him and Mr. W. Hannestad, in a necessarily brief 

 survey of insect depredations in the Koa forests. The follow- 

 ing day was spent again in company of Mr. Lindsay in an 

 examination of insects affecting pineapple, sisal, citrus and 

 peach trees. The pineapple in places was found thickly in- 

 fested Avith a pineapple scale {Aulacaspis hromdiac, Kern.) 

 •and with more or less mealy bug {Pseudococcus sp.). The trees 

 showed evidence of neglect and perhaps the worst pest of the 

 place is "Oi" (ycrhinaccae?) . This wiry weed constitutes a 

 serious problem in the sisal field there. Siphanta v/as very 

 abundant, especially on tender shoots of mango trees. Ripen- 

 ing mangoes suffered severely from fungus. Mr. D. D. Bald- 

 win claimed to have reared a moth, the caterpillar of which 

 was injuring mango blossoms. Unfortunately his specimens 

 were not preserved. Here I demonstrated to satisfaction that 

 the side of the tree and fruit exposed to the sun is least af- 

 fected by the disease.
