652 FAUNA HAWAIIENSIS 



clothing distinctly squamose. Elytra with series of punctures, which are finer than is 

 usual in the genus, the clothing of depressed pubescence with a tendency to become 

 maculate, and with numerous short erect setae. Basal abdominal segment beneath 

 densely punctate, some of the punctures deeper and larger than the others. 



Length 8 mm. In very fresh and densely clothed specimens the sculpture is 

 almost entirely hidden. 



Hab. Oahu ; lower slopes of the mountains, below the forest. 



(4) Rhyncogonus oleae, sp. nov. 



Black or piceous, probably sometimes red, clothed with fine pale hairs. 



Head between the eyes rugose-punctate, the rostral portion in front of this 

 usually more sparsely punctate. Eyes moderately convex. Two basal joints of the 

 funicle of the antennae slender and strongly elongated, the first a little longer than 

 the second, but in one J they are of equal length, third and following much shorter 

 than the second, but all of them elongate, basal joint of club distinctly longer than the 

 last funicle joint. 



Pronotum generally closely and sometimes rugosely punctured, generally more 

 densely in the Z than the female, sometimes quite dull, sometimes smooth and shining 

 between the punctures, which are usually uneven in size ; a median smooth line is 

 distinct, except sometimes posteriorly ; sides of thorax with denser and more conspicuous 

 pubescence in the female, usually less clothed in the ^. Elytra finely pubescent, with 

 about 1 2 rows of punctures on the dorsal surface, the pseudepipleura also pubescent, but 

 not maculately so. Two apical segments of the abdomen beneath in the ^, with somewhat 

 dense pubescence, at least much denser than on the preceding segments ; in the female 

 the segments are more thinly clothed, the clothing of the penultimate segment not 

 much different from that of the preceding, the metasternum at the sides much more 

 conspicuously pubescent than in the middle. 



Most similar to R. freycinetiae, which is a much blacker insect and otherwise 

 different in detail. 



Hab. Oahu, Waialua i 200 ft. ; on Olea, Euphorbia, etc. 



(5) Rhyncogonus fuscus, sp. nov. 

 Fusco-niger, setis appressis rufescentibus vestitus, opacus, antennis tibiis (plus 

 minusve) tarsisque rufescentibus. Caput minus dense punctatum, oculis fortiter pro- 

 minentibus. Pronotum inaequaliter punctatum, peropacum, latum, lateribus fortiter 

 rotundatis. Elytra vix maculatim ubique rufo-setosa, pseudepipleuris dorso minus 

 dense vestitis, opaca, interstitio tertio subelevato. Antennarum funiculi segmentum 

 primum et secundum aequilonga, sequentibus, quae aequilonga sunt, multo longiora. 

 Long. 7 '5 mm. 



Hab. Oahu ; Waianae mountains.
