its adjacent slopes. The subject will necessitate my giving long 

 lists of scientific names, and is consequently not an attractive one 

 to listen to, but I think the account will be foimd of considerable 

 practical value to members who are interested in the native 

 Hawaiian fauna, as, indeed, it would be to any transient ento- 

 mologist ha,ving a few days or weeks to spare in entomological 

 work. I may say that Tantalus is a rich locality, much richer 

 than many other parts of this island, which would appear more 

 attractive and productive on account of their far finer and more 

 extensive forest. It is too, very accessible up to 1500 feet 

 elevation, either by riding, driving or walking, and the actual 

 summit can be reached in an hour and a. half on foot from 

 Honolulu itself. By "Tantalus" in this paper I mean the peak 

 itself and all its slopes, i. e., all the ridges that lead up from the 

 plains to its base, as well as the steep side running down into 

 the Pauoa valley and similarly the steep side bordering Manoa, 

 but these two valleys themselves are not included. The main 

 range lying behind Tantalus is entirely excluded. It is much 

 wetter and more windswept than the latter and has, as is usual 

 under these conditions, a scantier fauna, though some of its 

 species are peculiar, while the Tantalus region has many that 

 are not found on the highest mountains. For instance I may 

 cite the six fine species of Longicorns belonging to the genera 

 CalUthmysus, Plagithniysus, and Clytarlus, which are entirely 

 absent from the higher elevations, not being found at an eleva- 

 tion greater than that of the summit of Tantalus, and more 

 usually some hundreds of feet lower still. 



No doubt in 1892 when I first spent a day in collecting on 

 Tantalus, it was decidedly a better collecting ground than today, 

 the changes that have taken place since that time being very 

 great. It was not, however, until 1900 that I did any systematic 

 collecting in this locality, and in the past five years again I 

 notice many changes all tending to its impoverishment as a 

 collecting ground. Still at present these are not so great as to 

 lead one to suppose that any species ha\'e been exterminated, 

 and in fact it is extremely unlikely that such has been the case, 

 since I ceased collecting in 1902. A recent visit leaves no doubt 

 in my mind on this point, but it would not be at all surprising to 

 find, now the locality is comparatively thickly inhabited, that 

 in a few years the native fauna will considerably decrease.
