Pronotum minus latum, antice impressum, minus dense squamoso-vestitum, lateri- 

 bus parum fortiter rotundatis. Elytra angustula, maculatim squamosa, asperula et 

 punctata (puncturatione et sculptura saepe exudatione lutosa celatis), setis erectis 

 brevissimis nee conspicuis, angulis humeralibus plerumque fere rectis. Femora postica 

 minus fortiter clavata, lobis tarsorum anticorum parvulis. ? %. Long, vix 2 — 3 mm. 

 (Plate IX. fig. 9, t.) 



Chiefly remarkable for its flattened, or even sub-depressed form, and generally for 

 the narrow elytra, which bear a number of roundish squamose spots, these spots 

 being paler in colour than the rest of the surface, whether this be red or blackish. The 

 sculpture is generally obscure, the punctures at least being generally filled up with a 

 muddy excretion, and not infrequently the insect has nearly the whole surface thickly 

 covered and concealed. The antennae, which are rather short, are generally entirely 

 of a clear red colour ; the rostrum of the $ is also red or reddish, its surface smooth and 

 shining, with the longitudinal grooves fine. 



Hab. Kauai, common generally. Many examples taken exhibiting variation in 

 colour, size and other respects. 



B. Species insulae Oahu propriae. 



(30) Proterhinus kamptarthriis, sp. nov. 



Niger vel piceus, antennis tibiis tarsis elytrisque rufescentibus, his plerumque plus 

 minusve nigro- vel fusco-maculatis. Antennarum articulo primo tertioque perelongatis, 

 illo incrassato. Pronotum minus latum, 3-impressum. Elytra pallide squamosa, humeris 

 productis. Antennarum $ articulus tertius subcurvatus. ^ ?. Long, circa 3 mm. 

 (Plate IX. fig. 10, t.) 



Black or piceous, with red elytra, which are usually sparsely spotted with black. 

 Femora dark, tibiae, tarsi and antennae wholly or partly red. Eyes prominent, in the ^ 

 very remote from the thorax. Antennae long, extremely so in the J, the scape 

 incrassate, and very elongate, second joint short, third extremely long, slightly but 

 distinctly curved in the <y, and perceptibly so in the ?, club distinctly of three joints, the 

 9th being considerably wider at the apex than the 8th. Prothorax rather narrow, with 

 three more or less evident impressions, rather scantily covered with pale squamosity. 

 Elytra covered with grey appressed scales, and with sparse erect white setae posteriorly, 

 the sides sub-parallel. The humeral angles are strongly produced, and the basal 

 tubercles near the scutellum are present, but there is no trace of longitudinal ridges. 

 Lobes of the tarsi by no means large. 



Hab. Oahu, Waianae mountains (3000 ft.) ; three % taken in April 1892, and 

 two males February 1896.
