THE FORESTS OF NEW ZEALAND. I 23 



in which to see the majestic kauri trees is the Waipoa forest, 

 Nokianga. This forest of 30,000 acres has recently been 

 demarcated — a first stage in real forestry, and will be opened 

 up by a railway and numerous roads after the war. There will 

 also be accommodation for visitors at the " Forest Stations," 

 which are placed in carefully selected and commanding positions 

 for the sake of outlook against fire. These localities afford 

 superb views over the forest, and a freedom from the sand-flies 

 and mosquitoes which are troublous at certain seasons in the 

 forest. The three best kauri forests are Waipoa, Wara-wara, 

 and Puketi, near the west coasts of the far north, lat. 35 , and 

 total some 75,000 acres altogether. 



The beautiful beech forests of the south, so much like the 

 European beech forests, and so pregnant with possibilities of 

 economic improvement, are best seen from Queenstown and the 

 head of Lake Wakatipu. South of this, the Milford Sound walk 

 is full of forest interest, but the walk which easily surpasses all 

 others for the forester is that down the west coast beyond Ross. 

 It was here I measured the tallest tree yet recorded in New 

 Zealand — a white pine of 210 feet in height. 



18. A Bark Beetle, Cryphalus abietis, Ratz. 



Under the heading of "The Structure, Bionomics and Forest 

 Importance of Cryphalus abietis, Ratz.," by Walter Ritchie, B.Sc, 

 Carnegie Research Scholar in Entomology, University of Edin- 

 burgh, there appeared, in vol. v., Nos. 3 and 4, of the Annals 

 of Applied Biology, a paper of considerable importance to the 

 forester. 



In it Mr Ritchie sets forth the results of his researches 

 into the structure, life-history and habits of the bark beetle, 

 Cryphalus abietis, Ratz. Material for the work was obtained in 

 Aberdeenshire, Kincardineshire and Midlothian. 



Of the six species of Cryphalus recorded in Fowler's 

 Coleoptera of the British Isles, two, namely C. abietis, Ratz., and 

 C. piceoz, Ratz., are bark beetles attacking conifers, while the 

 others are found on broad-leaved trees. The two species found 

 on conifers were formerly considered rare, but records of C. 

 abietis have been obtained for many districts in Scotland, so
