 the best materials to use are discussed, and some account is given 

 of both dusting and liquid spraying.

As a result of an agreement between the Italian Ministry of the 

 Colonies and the National Society of Olive Growers a collection of 

 Opius concolor, the parasite of the olive fly [Dactis oleae], has been made 

 in Tripoli. Some of the specimens were reserved for breeding in the 

 laboratory at Portici, whilst 3,260 individuals were released between 

 October 1917 and February 1918. It is hoped to effect a similar 

 collection this year.

Though not so utilised at present, the Urticaceous plants of the 

 genus Cecropia possess considerable potential value for paper-making. 

 Their chief enemy is a Chrysomelid beetle, Coelomera lanio, Dalm., 

 Cecropia cinerea being the species which is chiefly attacked. The 

 eggs of C. lanio are laid in masses of about 100 attached to the under- 

 side of the leaf. The larvae remain in groups and feed on the under- 

 surface until the leaf is skeletonised. 



The ornamental tree, Pachira aquatica, is attacked by the Longicorn, 

 Dryoctenes scrupulosus. Germ., the larva of which bores into the trunk 

 in all directions.

Great injury to gardens and potato fields by the Meloid beetle, 

 Epicauta atomaria. Germ., is reported. . Spraying with arsenicals 

 provides a remedy, but where only a few plants are attacked, hand 

 collection is preferable.
