126 FAUNA HAWAIIENSIS 



(8) Rhyncogonus freycinetiae, sp. nov. 



Niger, subnitidus, elytris vix pubescentibus, capite circa basim minus dense 

 punctato. Prothorax latus, trans medium evidenter latior quam longior, lateribus linea 

 pubescentiae continua ornatis. Elytra subnitida, interstitiis laevioribus. Abdominis 

 segmentum tertium ventrale $ aeque ac quartum pubescens. $. Long. 1 1 mm. 

 (Plate VII. fig. 4.) 



Female black, and somewhat shining, in general appearance very like that of R. 

 molokaiensis. From that species it may easily be distinguished by the less close 

 puncturation of the base of the head ; the much wider and more depressed thorax, with 

 continuous lateral lines of pubescence. The ventral surface of the hind body is also 

 more pubescent, the third segment hardly less clothed than the fourth. 



Hab. Oahu, Halemano (2000 ft.) ; i % taken at the bases of the leaves of 

 Freycmetia.

(10) Rhyncogonus koebe/ei, sp. nov. 



Niger, baud nitidus, antennis pedibusque rufescentibus. Caput sublaeve, sparsim 

 punctatum. Prothorax subtilissime pubescens, densissime rugoso-punctatus, lateribus 

 fortiter rotundatis. Elytra peropaca, parcissime pubescentia, apicibus liberis. $, Long. 

 II mm. (Plate VII. fig. 5.) 



Dull blackish, the antennae and all the legs dull reddish. Head smooth and 

 shining, sparsely punctured, the eyes very little prominent. Second joint of the 

 antennae rather longer than the third, the basal joint of the club longer than the apical. 

 Thorax very finely pubescent, densely rugosely punctured, its sides strongly rounded. 

 Elytra dull, with very little pubescence, the puncturation somewhat irregular, their 

 apices free, subdivergent. All the femora clothed with very short pubescence, that on 

 the tibiae longer. Apical ventral segment of the hind-body widely truncate at the 

 apex, densely clothed with pale pubescence. The species is very remarkable for the 

 condition of the eyes, which are much less prominent than in any other.
