seem to have a very limited area of distribution) this points to the 

 probability of their all being distinct from any I have described. 



After deducting the above 9 species as being (to me at least) 

 incapable of identification, and allowing for several cases of 

 synonymy, there remain 36 descriptions known to me as anterior 

 to my work, all of which I believe to represent good species. Of 

 these I have succeeded in identifying only 13 with insects before 

 me, and these will be found referred to in their places in my 

 work. 



Of the remaining 23, 9 are from Tasmania and are very likely 

 to be confined to that island (whence I have described only one 

 new species) and 2 are from Raffles Bay, another isolated locality 

 likely to produce species different from any I have seen. I have 

 nothing before me agreeing satisfactorily with the description of 

 any of them. 



There then remain 12 species which (although I have been 

 unable to identify them as represented among those before me) 

 might appear likely on a priori grounds to be present there. Con- 

 cerning 8 of these the descriptions supply sufficient information to j 

 enable me to feel fairly confident that I have not seen them ; they ' 

 are holortielcenus^ Blanch., laticeps, Burm., peUiccidus, Burm., 

 2:)lanatus, Burm,, ^^rax-wjms, Burm., rubricepSj Blanch., 7^i(/o- 

 onarginatus, Blanch., unguiculatus, Burm. 



The remaining 4 (viz., laticollis, Blanch., nigritiis, Blanch,, , 

 pilosellus, Blanch., oblo7igus, Blanch.), are quite insufficiently I 

 described by their author, and it is possible that I have re- 

 described some of them. 



The most convenient method, in adding a last word here and 

 there to correct faults and furnish descriptions of species that 

 have come into my hands subsequently to my having dealt with 

 the aggregates to which they belong, will be to divide the species 

 into groups (following the same classification as previously), and 

 discuss those groups separately. I shall take them thus : —
