Oodemas yields three species of these brassy weevils and Anothe- 

 orus montanus feeds in dead wood of various trees, Acacia, 

 Aleurites, and Pisonia. 



The interesting Heteramphus filicum is found in stems of tree 

 ferns, and no doubt the other species can be obtained on the 

 steep sides of Manoa. Three or four species of Xyleborus burrow 

 in sickly or dead trees, and probably others remain to be 

 discovered. 



In Proterhinus, Tantalus is very rich and it is unlikely that 

 much, if anything, new will be obtained in this line, though it 

 should be said that one or two are yet undescribed. Some of 

 the species are excessively difficult to obtain, especially those 

 that burrow in the hardest tree trunks and have to be cut out. 

 Others are extremely abundant. Some species attack many 

 trees even introduced ones, but others are absolutely attached to 

 a single kind. Proterhinus ruficornis is local, squamicollis rare; 

 vbscuricolor, subplanatus, angularis and archaeus are all on 

 Straussia; simplex, obscurus and vestitus on various trees, being 

 polyphagous; oscillans and vicinus on Koa; pusillus on Pelea; 

 dispar on Wikstroemia; blackburni on various trees and ferns; 

 deceptor on Hau and some other trees; longulus on tree ferns; 

 vahuensis in hard tree trunks ; oxygonias and one or two others as 

 yet imperfectly known. Blackburn's P. paradoxus and P. 

 ■oahuensis are the rarest and most desirable species, the former 

 not having been found since it was first collected. Two endemic 

 Tenebrioni'ds Cistela crassicornis and apicalis occur very rarely, 

 and Labetis, a pec\iliar genus, two species of which were taken on 

 Oahu by Blackburn, should turn up. 



Many native Cioidae are to be found, most of them feeding 

 on miscropic fungi in dead wood, but a few prefer the large woody 

 growths on various trees. Cis alienus and pacificus, especially 

 the latter, may not be really native, but the endemic species are 

 ■ cognatissimus, tabidus, bicolor, insularis, porcatus, setarius, 

 calidus, signatus, roridus, evanescens, and laeticulus; of these 

 calidus, insularis and roridus are the least numerous, but none 

 are very rare. Two or three species of apterocis are found. 

 ephistemoides being one of the commonest of beetles. 



Anobiids are not well represented, only one or two species of 

 Mirosternus and the same of Xyletobius and Holcobius being 

 found. Their headquarters in Oahu is the Waialua end of
