 insect life. 



Fagaceae.

 order is of a highly archaic type, known elsewhere only among the primitive 

 Casuariniae (she-oaks, etc.) of Australia. If antiquity, then, were a claim to 

 representation in the New Zealand forests, this family should be conspicuous 

 by the number of its species. It is, however, represented here only by some
