seventeen of these must be considered as synonyms, or, at 

 most, variations of previously-described species. Some of 

 these have been indicated by himself, others were 

 unfortunately published in papers which nearly synchronized 

 with those by M. Kerremans, so that each of these writers 

 sometimes repeated the work of the other. By the courtesy 

 of Mr. Edgar R. Waite, of the South Australian Museum,. 

 and the co-operation of my friend, Mr. A. M. Lea, I have 

 had the loan of a large number of specimens, including many 

 of Blackburn's co-types, or specimens bearing labels in Black- 

 burn's handwriting. This has been supplemented by similar 

 help from Mr. Kershaw, of the National Museum, Melbourne, 

 so that I have been able to determine with accuracy almost 

 all the species named by this diligent entomologist. Further, 

 a notebook containing the late Canon Blackburn's copious 

 notes on various Coleoptera has been entrusted to me, in which 

 is an outline of a tabulation of the genus Stigm odera . While 

 not following the same method in my own tabulation, this 

 has been of use in a few cases of species unknown to me. 

 Besides the material mentioned above, all the unnamed or 

 doubtfully-named specimens in the Macleay Museum, the 

 Brisbane Museum, the Perth and Tasmanian Museums have 

 been sent to me, together with the fine private collection of 

 Mr. Lea. My own collection — largely taken by myself in 

 twenty years' collecting in every Australian State, except 

 South Australia, is a good one — and I am further indebted 

 for specimens to Mr. C. French, Mr. H. W. Brown (the 

 widest of our field collectors), and Mr. H. Hacker. In 1907 

 I visited the Museums of Brussels, Paris, and England, taking 

 notes on specimens, especially in the Hope Museum, Oxford, 

 and the British Museum (which last had recently purchased 

 the fine collection of M. Kerremans), and I was thus able to 

 compare specimens with many types. With this material I 

 have ventured on a task that would otherwise have been 

 insuperable, in the hope that, the tabulation may render 

 identification easier to collectors, and at the same time purge 

 our catalogues of useless names. Probably some errors will 

 occur, but at least this tabulation will afford a basis for future 

 workers. Lastly, I would pay my homage to the great 

 specialist in Biiprestidae, M. Chas. Kerremans, whose cheery 

 acquaintance.- 1 had the honour to make in 1907 and whose 

 correspondence I have valued since. His standard work in 

 the "Genera Insectorum" has been of great assistance to me. 

 and I have, in part, followed his subdivision of the genus into 

 the three subgenera mentioned below. Whatever be the value 

 of these subdivisions zoologically, they are very helpful in 

 classifying so large a genus. I had hoped to see the-
