Parasitism among the larvae of the Mediterranean fruit fly (Ceratitis 

 capitata) in Hawaii during 1915, E. A. Back and O. E. Pembeeton {Jour. 

 Econ. Ent., 9 {1916), No. 2, pp. S06S11) —The authors present tables to show 

 the percentage of parasitism among C. capitata larvse developing in coffee 

 cherries {Coffea arabica) in the Kona District, in kamani nuts {Terminalia 

 catappa) in Honolulu, and in various host fruits grown in Honolulu. The data 

 for 1914-15 shovs' that four introduced parasites, Opius hvmilis. Diachasma 

 tryoni, D. fullawayi, and Tetrastichus giffardi, have established themselves and 

 are already promising much as a factor in the control of the fruit fly.

 of white grubs are said to have been reared from egg to adult and adults of nine

 a brief summary of life history studies, comparison with related genera, field 

 observations, natural enemies, and methods of control.
