I am quite aware that the above list is incomplete. It may, 

 however, be accepted as an Operum prodromus. Since 1842, as 

 far as I am aware, Mr. MacLeay confined himself to occasional 

 anonymous notes, as for example, the remarks which appeared in 

 the Sydney Morning Herald — on Diprotodon and Zygomaturus. 



During the year 1864^ five Papers have been read before the 

 Society, and will appear in the forthcoming number of our 

 Ti-ansactions. A very important addition to om- knowledge of 

 Australian Scaritidce was afforded in a second paper on that rare 

 family by Mr. W. MacLeay, who also read a paper on a 

 new genus of blind insects, to which he has given the name 

 Ulaphanus. 



I was able myself to contribute a third paper on the 

 Pselaphidce, as well as papers on the Georyssidce, the Parnides, 

 and on the anatomy of certain forms of Australian Entomostraca. 



It is much to be desired that more of our members would 

 begin to describe the insects they find. By so doing, they 

 would benefit themselves, assist others, and help to redeem the 

 study of Entomology from being regarded as an idle collecting
