COLEOPTERA. 
(exclusive of the CarabidcE). 
By the Rev. T. BLACKBURN, B.A., Hon. Curator for Entomology of 
the South Australian Museum. 
The material on which this memoir is founded consists of about eight hundred 
specimens, representing about one hundred and forty-five species. Of these species 
I describe sixty-two as new to science, and among these latter are four for which I 
find it necessary to propose new generic names. There are also several species which 
are no doubt undescribed, but owing to their imperfect condition or the lack of 
examples of a sex indispensable to a satisfactory diagnosis, are not able to be dealt 
with at present. Considering the length of time spent in the work of the Expe¬ 
dition, the extent of the collection will probably appear meagre to those who have 
not collected in Central Australia. But my own experiences of the difficulty of 
obtaining specimens in that desert region assure me that the result is far from 
being unsatisfactory, and when it is taken into account that the naturalists of the 
Expedition had to divide their attention among a great diversity of objects, there 
appears to be reason for regarding the collection as an exceptionally rich one 
considering the circumstances under which it was made.
