This species is the weta - punga of the iNIaoris. Sir 

 W. Buller says that it appears to subsist chiefly on the green 

 leaves of trees and shrubs. It climbs with great agility, and 

 is sometimes found on the to^Dmost branches of lofty trees, 

 but generally on the low underwood of the forest. Dr. 

 Hochstetter says that it lives in rotten wood and under the 

 bark of trees.
