VI—MEMOIRS ON THE COLEOPTERA OF THE HAWAITIAN;ISLANDS. By 
Tue REV. T. BLACKBURN, B. A., anp Dr. D. SHARP. (Plates IV. and. V.) 
[Read, March 17th, 1884.] 
INTRODUCTORY. 
SEVEN years ago very little was known of the entomology of the Sandwich, or as 
they are now, perhaps more correctly, called the Hawaiian, Islands. About that 
time Mr, Blackburn commenced a residence in the archipelago, at Honolulu, and 
has since devoted as much time as the duties of his official position permitted to 
the subject of its entomological fauna. As the result of his activity, numerous 
Papers have been published in several scientific journals; and as Mr. Blackburn 
has now ceased to reside in the islands, we have thought it well to make what, so 
far as Mr. Blackburn’s researches are concerned, may be called a final resumé of 
our present knowledge of the Coleoptera. 
This object, it has appeared to us, might most satisfactorily be accomplished 
by Three Memoirs :— 
I. Descriptions of such genera and species as are hitherto undescribed.* 
II. A Systematic Catalogue, with a brief statement as to the habits, habitat, 
&ec., of each species. 
Ill. Topographical Table, accompanied by some generalizations, summaries, 
and comments on the Coleopterous fauna of the archipelago. 
IB 
ON SOME NEW SPECIES AND GENERA OF COLEOPTERA. 
In this Memoir, some of the descriptions have been made by Mr. Blackburn, 
and some by myself; they are arranged in sequence, our individual responsibilities 
being indicated by appending to each description the initials of the describer, viz. 
T. B. for the Rey. Thomas Blackburn, and D. 8. for David Sharp. The nomen- 
clature and classification indicated is very little, because all that is necessary 
is given in the immediately following Systematic Catalogue of Hawaiian 
Coleoptera.

* A short account of the Islands and of Mr. Blackburn’s collecting there is appended.
