From material collected near Santiago, Chile, in 1913, three females 

 of the Coccid, Margarodes vitium, Giard, hatched out in November 

 191f5. The foliage of fuchsias cultivated near Temuco was severely 

 injured bv the Chrysomelid beetle, Haltica virescens, Bl. Thri-ps 

 Uibaci is recorded — for the first time in Chile — from onions, tobacco, 

 potatoes, beet and ears of wheat ; it may be expected to infest other 

 plants and to become a pest if conditions favour it. In December 

 1916 peach trees near Santiago were severely attacked by the Curcu- 

 lionid, Lophotus phalemtus, Er. In March 1917 carobs at Limache were 

 badly infested by Bruchus pisorum, L. The Chalcid, Aspidiotipliagus 

 citrinus, Craw, was observed parasitising the scale, Fagisuga triloba, 

 Lindgr., infesting Sax^gothea conspicua and Notophagus dombeyi. 

 The latter plant was found also to be a host of Pseudoparlatoria 

 chilina, Lindgr., which up to then had been known from Saxegothea 

 conspicua only.

Pseudococcus adonidum was abundant in and around Santiago in 

 1916. This scale is preyed upon by Coccinella fulvipennis and Scymnus 

 {Parasidis) macula, Germ. In the same district Chrysopa porterina; 

 Navas, preys upon Eriosotna lanigerum with avidity.

Pieris brassicae, L. (cabbage butterfly) can be easily destroyed at 

 any stage of its development. The netting of the adults when they 

 come to oviposit on cabbages is a method of control too slow to be 

 practicable, but the use of poison-baits should be a means of destroying 

 large numbers during the many months of the year in which they are 

 on the wing. With a view to testing the usefulness of this method, 

 researches were conducted to discover the time elapsing between 

 emergence and oviposition. It was found that the dates on which 

 these spring butterflies emerge has no direct connection with the 

 age of the autumn pupae that give rise to them, while the eggs they 

 contain are far from being completely developed.

The general opinion obtaining among rubber planters in the Middle 

 East is that small boring-beetles, such as the Scolytid, Xyleborus 

 parvulus, and the Longicorn, Pterolophia melanura, are unable to
