that this insect is occasionally instrumental in destroyinir its 

 host tree. The habit of the adnlt in feeding both in decaying 

 and sonnd bark would probably serve at times to incx-ulate th(^ 

 living- tree with decay producing organisms. However, there 

 seems to be no indication that it is jiroducing any (-(msiderablc 

 injury, since the trees attacked are among the most vigorous 

 species of trees in the native forests. 



It is quite evident that the insect is not nncoiiniioii but 

 on account of the scattered trees which it attacks it is only 

 abundant in any one place when a fallen tree or dying tree 

 permits the development in numbers; ordinarily it attacks 

 only a branch here and a branch there, l)nt our observation 

 indicates that several of these branches might be found at 

 ahuost any time if carefully searched for. 



IMatc y\ sliows views of portions of the ti'unk of a tree 

 obs(M'ved l)y Mr. Swezey along the Manoa Cliifs Ti-ail on 

 Tantalus. It was a standing trunk of a large Cheirodendron 

 ( i(iii(/icliiiiu/ii tree, fi-om which the bark had fallen, exposing 

 thousands of tlic openings of the pu])al cells of this \vee\il. 

 K\i<lence was not at hand to determine whether the weevil 

 hirvae had been the cause of the death of the tree, or whether 

 their work was performed after the tree was dying froiu other 

 causes. 



The u))]>er surface of the rostrum in the male is ])rovi(led 

 with tuberculate spines ii'i'egularly disposed behind the 

 antennae and in an irregularly spaced series on either side in 

 fi'out; the rostrum is widened a little at the apex in the male 

 Isut not in the female; in the male the antennae are inserted 

 more than half way from the eyes to the tip of the beak, they 

 are greatly elongate, the sca])e and flagellum each as long as 

 the gi'eatly elougale beak, ;;ud the joints of the funicle are 

 provided with long loose bail's four or five times as louii' as the 

 width of the joints; in the fenuilc the antennae are shorter, 

 insei'ted about one-third tlie distance from the eyes to the 

 ajx'x and none of th(> hairs are longer than the width of » 

 joint. The last tergite of the female is pei^tinate along its
