DESCRIPTIONS 



OF 



NEW GENERA AND SPECIES OF COLEOPTERA, 



By Major T. Broun, F.E.S. 



PART VI. 



The preparation of this paper, owing to the prolonged microscopical study 

 necessary in describing such a large proportion of small species of Pselaphidae, 

 Cfyptorhynchidae, &c., has given me constant occupation for almost an 

 entire year. 



It contains descriptions of ten new genera and 173 species. All the 

 new genera, and 140 of the species, are the result of Mr. T. Hall's skill and 

 untiring perseverence, during the winter as well as the more favourable 

 and pleasanter collecting seasons. Mr. A. E. Brookes, of Mount Albert, 

 discovered eleven, Mr. A. Philpott, of Invercargill, six, Mr. H. W. Sim- 

 monds, of Wellington, six, Mr. J. H. Lewis, one ; the remainder belong to 

 my own collection. 



The delay m publishing my last paper, the work of 1914, added greatly 

 to the difficulties encountered when investigating the structural details of 

 the species enumerated in the following list. Only those actually engaged 

 in scientific work of this kind can form any idea of the complications created 

 by inability to refer to printed descriptions of previously named members 

 of an Order now known to exceed four thousand species. Even the 

 nomenclature, especially when species belong to genera represented in 

 other parts of the world, has become a very troublesome undertaking.
