Rhyncogonus koebelei Perkins.

What I believe to be the above species is common on Oahu from Manoa valley to 

 the south-eastern extremity of the Koolau range. It occurs as high as 2000 ft. in the 

 mountains, but is found at much lower elevations — under 1000 ft. Like others of the 

 genus, it is quite variable. The apical ventral segment of the female is pointed and 

 much less densely hairy than that of the male. Varies very greatly in size.

This species was originally introduced into the island of Maui ; subsequently it 

 spread to Oahu, and still more recently to Hawaii. It does great damage to cultivated 

 plants and forest trees in the mountains, but does not become abundant on the lowlands, 

 at any rate in the drier districts. It is polyphagous. It is the Paiifomorus olindae of 

 my earlier paper on the weevils. Seeing that it was evidently introduced into Hawaii 

 from the warmer parts of America, I did not look for its description amongst the 

 N. American fauna, it being no doubt an introduction also into California and other 

 parts from the same region. It seems to me not separable generically from true 

 Pantoiiionis. 



(i) Aealles pusillissimus, sp. nov. 



Nigricans, antennis, rostro, tarsisque rufo-testaceis. Antennarum articulus secundus 

 subovatus et elongatus, sequentibus brevissimis et transversis. Pronotum elongatum 

 anterius posticeque angustatum, setis brevissimis nigris inconspicue vestitum. Elytra 

 parum lata, lateribus aequaliter rotundatis, interstitiis (primo excepto) aequaliter con- 

 vexis, baud irregulariter elevatis, plaga pallida squamosa post humeros versus suturam 

 oblique utrinque currente. Long. 175 mm. 



This is the smallest species of Hawaiian Aealles, and is distinguished by its small 

 size, narrow form and the patch of pale squamosity, which tends to form a fascia on 

 the elytra and the e.xtremely short joints of the funicle of the antennae. Unfortunately 

 the type is not in good condition. A specimen, which I am not able to find in the 

 collection, was much more perfect, when taken, and not abraded like the one described. 

 I have met with it still more recently in the mountains near Honolulu. 



Hab. Oahu ; mount Tantalus ; occasionally met with, but not common.
