Considering the similarity of prunes to phims and the similarity of tho 

 almond to the Kaiiwini nut. these two might also servi' a.s hosts and lengthen 

 the list. 



This discus.>-ion, it will be noticed, is totally without refereni'c to climatic 

 conditions, the relation of which to tlu' fruit tly is very hard to accurately 

 determine. However, from the history of its work in .similar latitudes in 

 .\ustralia and South Africa, we have ample rea.son to think that should it by 

 ;iny means gain entrance to California, it could thrive in winter in some 

 stage in the .southern |»art of the state at least, and jirovc to this state and 

 i-ountry the most .serious pest of its history.
