COLEOPTERA 129 



Black, the whole insect clothed with somewhat dense pale pubescence, which is 

 rather in the form of very fine elongate scales, and to a large extent conceals the 

 surface, which is shining. The head in front is strigose and punctured ; the prothorax 

 densely punctured, the sides not at all strongly rounded, the surface shining, and with a 

 smooth narrow dorsal line, the sides more densely pubescent than the general surface. 

 The elytra in the Z are much depressed, with closely-set series of punctures, the surface 

 where not hidden by the pubescence, shining, and roughened with small tubercles. All 

 the legs clothed with pubescence, that on the front tibiae, as well as that of the scape of 

 the antennae, longer and more conspicuous than that of most of the species. The single 

 % which probably belongs to this species is much less depressed, and has a shorter club 

 to the antennae, its middle joint being not longer than wide, and the joints themselves 

 less distinct. 



Hab. Kauai, Halemanu (4000 ft.) ; 3 t and i %. 



{16) Rhyncogoims vittatiis, sp. nov. 



Niger, antennis pedibusque saepe plus minusve rufescentibus. Caput cum pronoto 

 squamulis pallidis vestitum. Elytra tuberculis nitidis asperula, fasciis longitudinalibus 

 pallidis ornata. ^ %. Long. 10 — 11 mm. (Plate VI. fig. 7.) 



Black, the antennae and legs often more or less red or piceous. The J is very 

 strongly flattened or depressed, the % sometimes of more convex form. The head 

 is strigose and punctured, but the surface is for the most part concealed by the covering 

 of scales and hairs. The sides of the prothorax are but little rounded, and slightly 

 convergent in front, the surface densely punctured and concealed by the pale squamous 

 pubescence. The elytra have each about six distinct longitudinal bands, formed of 

 minute pale scales, the spaces between these bands being sparsely clothed with similar 

 scales. The surface is roughened by shining tubercles, and the puncturation much 

 obscured. All the legs and the antennae are clothed with pale hairs. In both sexes 

 the entire ventral surface of the hind-body is conspicuously pubescent, but the basal 

 segments are less densely clothed than the apical. 



Hab. Kauai, mountains (3000 ft.) ; not common. 



(17) Rliyncogomis tuber ailatus, sp. nov. 



Minor, haud nitidus, totus pubescens, nigro-piceus, antennis pedibusque rufescenti- 

 bus. Caput strigosum. Elytra tota fusco-pubescentia, seriatim punctata, tuberculis 

 rare dispositis munita, apicibus haud liberis. ^ %. Long. 8*5 — 9 mm. 



A small species, entirely clothed with fuscous pubescence, the ^ strongly depressed. 

 Head strigose ; antennae with the first joint of the funiculus subequal to the second ; in
