planting of tops infested with Diatraea seemed to be largely responsible 

 for the appearance of this insect in newly planted areas and the con- 

 tinued infestation in older ones. Termites were reduced in numbers 

 in many areas. Caslnia licus (giant moth-borer) appeared to be 

 increasing on some estates. The collection of unparasitised egg- 

 masses of Diatraea was begun on some estates which had previously 

 neglected this operation and a small number of egg- parasites were 

 distributed. The rice crop was successful and no complaints were 

 received of insect pests. Rubber continued to be unaffected to any 

 extent by insects. The larva of Castnia daedalns attacked coconuts 

 over a considerable area. A Plant Protection Ordinance is necessary 

 to deal with tliis insect and also with Brassolis sophorae, which was 

 abundant on coconut palms near Georgetown. The adults of Strategus 

 aloeus, L., were troublesome on young trees and the presence of 

 Aspidiotus destructor in some localities was due to poor drainage and 

 consequent low vitality of the trees. Among the pests of cacao and 

 coffee, the coffee leaf-miner occurred in numbers in some districts. 

 Numerous seeds of Elaeis guineensis (West African oil palm) failed 

 to germinate on account of infestation by the Bruehid, Pachymerus 

 (Caryoborus) nucleoriim, F. The eggs are deposited in one of the 

 germinating holes which traverse the hard covering of the seed, after 

 the latter has fallen to the ground. The larva passes to the interior 

 of the seed and there feeds ; when mature, pupation takes place 

 within the seed. The adult emerges through a hole formed bv the 

 jaws in the side of the seed coat. About 70 per cent, of the seeds 

 gathered beneath the palms were infested. Lists of insects attacking 

 sugar-cane, rice, coconut, etc., and some of their parasites, are given 

 [see this Revieiv, Ser. A, i, p. 521, ii, pp. 57, 416, 520, 568].

The author refers to the statement of N. Sacharov that Antlionomus 

 pomoram winters in the forests, situated near orchards, wliich would 

 account for the failure, in many cases, of remedies against this pest, 

 such as sticky belts or washing the trunks of apple trees with lime.

Great damage is done by Cydia ponionella in Turkestan, where three 

 generations of it occur and where the method of bag-treatment is 

 rendered more expensive and troublesome owing to the gi-eat height 

 to which the local trees grow. The method of utilising the 

 infested and fallen fruits, facilitates the breeding and spread of the 

 pest and greatly aggravates the situation. In the Crimea, the rejected 

 fruits are usually exported outside the horticultural region into the
