Bag-Shelter Moths attacking Wattles.— ^^rrtc. Gaz. N.S.W., Sydney, 

 xxvii, no. 6, June 1916, p. 440. 



The Notodontid, Teara contraria, has recently caused serious damage 

 to wattles in the Scone district of New South Wales. This insect 

 occurs throughout the central and Avestern portions of Austraha, 

 attacking various species of wattles. Control measures include the 

 destruction of the nests, spraying with lead arsenate at the rate of 

 2 lb. to 50 gals, water, and breaking up the soil below affected plants 

 to expose the pupae.

The most important insect pests of limes in British Guiana are scale- 

 insects, including Lepidosaphes beckii, Newm. {Mytilaspis citricola, 

 Pack.), and Chionaspis citri, Comst. These are best controlled by 

 spraying with resin wash, prepared according to the formula, 8 lb. 

 resin, 6 lb. washing soda, 4 gals, water ; the stock solution is diluted 

 four or six times before use. Pseudococcus citri, Risso, on leaves and 

 fruit, can be destroyed by spraying with kerosene emulsion, prepared 

 by diluting to six times its volume a stock solution consisting of 2 gals, 

 kerosene, | lb. soap and 1 gal. water. The ant, Atta cephalotes, L., may 

 be troublesome in newly-planted areas. The nests may be destroyed 

 by " puddling," if the soil is not too sandy, by fumigation with carbon 

 bisulphide or sulphur fumes, or by the construction of a trench filled 

 with water round the nest. The caterpillars of Papilio anchisiades, 

 Esp., may attack the foliage. They feed only at night, and during the 

 day congregate near the base of the tree, thus rendering their collection 

 an easy matter.

Living trees are not attacked by the Anobiid, Oligomerus 

 hrunneus, 01., which has been found infesting the wood of beech, oak, 

 walnut and other fruit trees and also infests furniture. Attacked 

 timber shows holes of 2-3 mm. in diameter through which frass and 

 excreta are ejected and the adult insect escapes. The galleries measure 

 from 0"2 to 5'0 mm. in diameter and contain chambers at intervals. 

 Pupation takes place within these and the adults are also often found 

 in them. It is difficult to indicate the length of the larval period. 

 The adults appear from early April to late September. The pupal 

 stage lasts from eight to nine days. In an unsuccessful search for the 

 eggs of this Anobiid a number of female specimens of Pediculoides 

 ventricosus, Newp., were discovered. This Acarid was repeatedly 

 found in fine frass from furniture, but never in frass in timber out of 

 doors. Experimentally, however, when P. ventricosus was placed in 

 bores in outdoor timber the beetle larvae were soon attacked and killed
