Since that date a considerable amount of investigation work hasbeen carried out regarding the relation of this family to the forests ofthe country by officers of the Department and others and by myself;many new species have been discovered, and valuable records on theireconomic importance have been compiled. This information is detailedin the following pages. Whilst some of it has been already publishedin my monographs and bulletins, much of it appears here for the firsttime. 41 51 61 71 81 91 HOlllFlill MJ3I 4. V-t O otc ,.
