Bay, Middle Island, New Zealand. The cave is close to tlie seashore, 

 and near a very large coal deposit, which occasionally crops out in the 

 interior. The HadencEci were rather numerous, but very difficult to 

 catch, disappearing in the crevices of the rocks on the approach of 

 lights. They appeared to be most abundant near the streams of 

 water which percolated through the rocks. The sex of my specimen 

 cannot be determined. 



The genus Hadenoecus is of peculiar interest, for its members are 

 confined to the deepest caves, and no other Orthopteran genus is 

 known to be Hmited in this way. Up to this time three species have 

 been discovered, from very distinct localities; they are the follow-
