 reduced to a condition of miserable monotony. 



In England, I am happy to say, entomology is being more 

 appreciated every day, the number of entomologists having 

 increased enormously during the last twenty years. The 

 Entomological Society of London alone consists of over three

 societies in London devoted almost exclusively to the same 

 science. Surely a few inquiring minds in New Zealand will 

 turn their attention to a study which offers a boundless field 

 for investigation, coupled with inexpensiveness and plenty of 

 out-of-door recreation.
