upon myself to deliver a Presidential address on an entomological 

 subject in conformity with the precedent which seems to have 

 been established by my respected and talented predecessor. Our 

 By-Laws make it obligatory for the President to deliver an address 

 at the Annual Meeting, and I have therefore decided that my 

 subject on this occasion shall relate to a visit of 3)^ days which I 

 made recently to the Island of Lanai, during which short period 

 barely one-half of my time could be devoted to collecting of 

 insect fauna. 



From the Rev. T. Blackburn's Resume of his journeys and 

 collecting on these Islands the following extracts are taken as 

 descriptive of Lanai, and they may be considered serviceable for 

 the purpose of this address. " This island (Lanai) lies due West 

 of Maui from which it is separated by a Channel 9 miles wide. 

 It is one of the smaller islands, having an area of only about 150 

 square miles. Its highest summit has an elevation of about 3,400 

 feet and the mountains occupy an unusually small proportion of 

 area to the plains ; moreover the forest is here less extensive and 

 dense than in most parts of the Archipelago." * * * * "^g 

 a rule the insect fauna of the island appears to be closely related 

 to that of Maui, but only a few of its insects seem absolutely 

 identical with those of its neighbor; I feel compelled to regard 

 them in general as species in course of acquiring complete isola- 

 tion and therefore incapable of being treated as mere varieties. In 

 the few patches of forest that I explored it appeared to me that in- 

 sects were more plentiful than might have been expected." 



Comparatively speaking I do not consider that Lanai is at 

 present as rich in insect life as Hawaii, Maui, Molokai or Oahu. 

 It was not considered so by Dr. Perkins some years ago when he 

 spent quite a little time on the island investigating it entomologic- 

 ally. Mr. Blackburn's visit there was some years prior to that 

 of Dr Perkins', and covered a period of one week only, during 

 which he collected the following endemic and introduced beetles : 

 (See Tra?is. R. Dublin S. 1885.) 



Endemic 17 species 



Introduced 18 

 Of the endemic beetles no Carabids, Rhyncogonids or Plagith- 

 mysids were taken by him.
