infested worse with Icenja than any of his neighbors, and attributed it to the bring- 

 ing home of boxes of California fruit at the arrival of every steamer. 



This gave me a clew as to how the Ictrya might have come here. I found that all 

 the trees (principally samang) on the leeward side of the Calitornia Fruit Store (so- 

 called) were very badly infested with this scale, whilst within a quarter of a mile 

 distant none could be found, and even trees of the same kind (samang) about 60 feet 

 to windward I found perfectly clean ; the same results with other fruit stores, only 

 there were not so many trees near by. This was in May. I have no doubt that we 

 are indebted to our California friends for this pest, but as they have been otherwise 

 kind to us we readily forgive. 



3. Z)ama<7e.— None to speak of; a few of course; have cut down some good trees, 

 although they were advised not to. 



4. Plants attacked.— A\i of the citrus family, samang, casuarina, mesquite, ban- 

 yan, bread-fruit, mango, vi ; various shrubs, such as roses, hibiscus, crotons, etc., in fact, 

 nearly everything except eucalyptus, pafais and sugar-cane. An experiment to in- 

 fest the latter with Icerya failed on account of the arrival of the Vedalia shortly 

 afterwards. 



5. What remains of the. Icerya.— Two boys who have been supplying my Vedalia cage 

 with Icerya all along, told me on November 15, 1890, tbat no more of the food could 

 be found anywhere. The boys have their -own horses and were only too anxious to 

 earn their 25 cents a day, but I knew from my own observations that they were cor- 

 rect and I gave up the cage. Since then some few of the Icerya have been noticed, 

 but I don't think that they ever will become a pest again. 



There is this, however, to be said : That for some months past nobody has seen a 

 Vedalia here, and it would be impossible for me to-day to produce a specimen of this 

 insect in any of its stages. During August and September last they were so abun- 

 dant under many of the trees that one might have scooped them up with a shovel. 

 The probability is that the Vedalia will make its appearance again shortly.— [A.
