Hydropsyche fimbriata. 

 H. colonica. 

 Hydrobiosis umbripennis. 



All these and several other closely allied species of Trichoptera were 

 seen in numbers. 



DiPTERA. 



In addition to several rare species of flies not yet determined, the 

 following species of crane-flies (" daddy-long-legs ") were observed. 



Macromastix montana. 



Very common on Mount Ruapehu at about 5,000 ft. 



Limnophila sinistra. 

 L. argus. 



Both these species were very common in forest at Ohakune. 



Tipula viridis. 



Several in forest. 



Tipula novarae. 



One seen on Mount Ruapehu at 5,000 ft. 



Tanyderus annuliferus. 

 Two seen. 



Dilophus nigrostigma. 



Common on Mount Ruapehu at 4,500 ft. 



COLEOPTERA. 



Metriorhynchus erraticus. 



This beautiful beetle was very common on dead logs in the hot 

 sunshine. 



Stethaspis suturalis. 

 Several observed. 



Beetles generally were not much in evidence, although the locality 

 would probably prove a good one if adequately worked by a coleopterist. 



Orthoptera. 



A large yellow-green grasshopper with blackish markings and 

 rudimentary wings was very common on Moun^^ Ruapehu at about 

 5,000 ft. It is apparently closely allied to several specie ^ found on 

 mountains in the South Island. 



Miscellaneous Observations. 

 A peculiar cracking sound was heard on severa' different days 

 proceeding from the middle of a dead tree standing in the forest, and 

 was, I think, due to a large number of weevils (probably belonging to 

 a species of Psepholax) drilling their way our of the tree. When the 

 trunk was violently kicked the sound stopped, but it always resumed 

 two or three minutes afterwards.
