bodies, which alone would be inefltective. Liver of sulphur alone 

 cannot control the American gooseberry mildew, but gives very good 

 results with this emulsion, as does also a dilute solution of nicotine, 

 which, alone, has no decided action on adult caterpillars and only 

 kills Byturus tomentosus (raspberry beetle) vnth. difficulty.

The cherry sawfly is described, the control measures recommended 

 being the powdering of the leaves of infested trees with freshly slaked 

 lime, and the use of arsenical insecticides.

During 1915-16 the introduction of several serious pests from 

 foreign countries was prevented by careful inspection. Aleurodes citri 

 (citrus whitefly) was found several times on hothouse plants from 

 Florida, and Adoretus tenuimaculatus (Japanese rose-beetle), Anomala 

 orientalis and several closely allied species occurred in soil from the 

 Far East. In the latter part of 1916 a large colony of the Argentine 

 ant [Iridomynnex humilis] was found in plants from California, in 

 which State it has become widely distributed, causing much anxiety 

 on account of the damage done to stored food. This report also 

 contains a complete list of all the insects collected during the above 

 period.

Opius fletcheri, Silv., was successfully introduced in 1916 to control 

 Dacus {Bactrocera) cucurbitae (melon fiy). In many places this pest 

 is largely checked by predaceous Staphylinid beetles, and also by 

 Spahngia, a common Chalcid parasite of the pupa. Anagrus, 

 Paranagrus, Ootetrastichus and Gonatopus, four parasites of the eggs of 

 the corn leaf -hopper, were introduced from Manila, and Paranagrus 

 was propagated and established. The fruit-fly parasites, Tetrastichus 

 giffardianus, Diachasmafullawayi, D. tryoni, Dirhinus giffardi, Galesus 

 silvestrii and Opius humilis, were propagated and liberated. Paralep- 

 tomastix abnornd'^, which attacks several species of mealy-bugs, chiefly 

 Pseudococcus citri, P. sacchari, and probably P. bromeliae, was intro- 

 duced into California from Sicily, and from California into Hawaii in 

 1915. Parasites of the horn-fly [Lyperosia] that have been propagated 

 and liberated include Spalangia cameroni, S. philippinensis, Muscidi- 

 furax raptor and Pachycrepoideus dubius.
