As with many others, he at first did not specially mark 

 his types, but of late years he did mark them, and all of 

 those that were sent to the British Museum, and most of 

 those remaining in his collection, were marked T. 



Shortly before his death he sent many of the types to 

 the British Museum, and a list of these was kept. At the 

 time of his death he had two boxes filled with types, and 

 these, after being examined and listed, were also sent to the 

 British Museum. 



He also named many species from the collections of the 

 South Australian Museum. At the foot of his descriptions 

 of many of these the types are explicitly stated to be in that 

 institution. In talking the matter over with him only about 

 a month before his death he informed the writer that when 

 he had described specimens from the Museum only he re- 

 turned the types, to that institution, even when there were 

 numerous specimens of a species. Thus the types of the 

 beetles named from the Elder Exploring Expedition, from 

 Mr. Zietz's trip to Lake Callabonna, Mr. J. G. Otto Tep- 

 per's from Kangaroo Island and elsewhere, and Mr. J. P. 

 Tepper's from the Northern Territory, etc., should, with few 

 exceptions, all be in the Museum. < 8 ) 



Co-types of many of his species, however, are scattered 

 largely through his own and other collections, and his labels 

 at the present time are well known to all Australian 

 Coleopterists. 



The increasing importance atached to type specimens of 

 insects causes it to be of importance to Australian Coleop- 

 terists to know exactly where his types may be seen. I there- 

 fore went through all his papers and prepared a list of the 

 species described from Australia. He named many other 

 beetles, bugs, etc., from the Hawaiian Islands, but in the 

 appended list only the Australian beetles are dealt with. 



For the purposes of this list it was not considered desir- 

 able to give the usual abbreviations of the Transactions or 

 Proceedings of the Societies in which the descriptions 

 appeared, but to give a reference number to each paper con- 

 taining descriptions of Australian beetles. The following 

 abbreviations are also used : — 



Sub. Substitute-name, for preoccupied names. For 

 these names the types, of course, would originally 

 bear different names, and the actual specimens 

 were usually not known to Mr. Blackburn. 



(8) In some instances, however, he retained the actual type 

 specimens and sent them to the British Museum. Where, there- 

 fore, the specimens so sent were marked as types, the present 

 writer, in all cases, regards them as such.
