COLEOPTERA 209 



(50) Pi'oterhinus kaalae, sp. no v. 



Piceo-niger, antennis tarsisque rufotestaceis, minutus, sat robustus. Antennae 

 graciles, elongatae, articulo primo fortissime incrassato, clava distincte 2-articulata. 

 Oculi parvi. Pronotum grosse punctatum, setis erectis pallidis vestitum, haud squa- 

 mosum. Elytra brevia, lata, pronoto fere bis latiora, grossissime punctata, haud 

 squamosa, setis per elongatis albidis supra sex-seriatim vestita. Femora omnia cum 

 tibiis setis longis albidis vestita, tarsorum lobis anticorum sat magnis. Z- Lono-. vix 

 2 mm. (Plate X. fig. 3.) 



One of the smallest, but quite one of the most remarkable of all the known species. 

 There is no squamous clothing, but the erect setae are whitish, and very long and 

 conspicuous, and form three rows on each wing-case, those of the series next to the 

 suture being shorter than the others. The setae in each row are distant and very 

 regular, and of even length, not consisting of some short and some long ones intermixed, 

 as in most of the conspicuously setae species. Similar setae clothe the legs and thorax, 

 and the sculpture of the latter and of the elytra is very coarse. The lobes of the front 

 tarsi are rather large for the size of the insect, the claw-joint short, not projecting very 

 far beyond the lobes. The basal joint of the antennae is extremely wide, the inter- 

 mediate joints slender, the club consisting of 2 joints only. The elytra are short and 

 wide. 



Hab. Oahu. A single t was taken on Kaala in the Waianae mountains. 



(51) Proterhimis archaetts, sp. nov. 



Depressus, nigricans vel piceus, parum squamulosus, setis conspersis erectis sat 

 conspicue vestitus. Antennae rufae, articulo secundo sat elongate sed, quam tertius, 

 robustiore. Oculi prominuli, setigeri. Pronotum dense rugoso-punctatum, setis erectis 

 elongatis vestitum. Elytra parum vel haud squamosa, setis erectis sparsim sed con- 

 spicue vestita, crebre confuseque punctata, dorso deplanato vel depresso, basi utrinque 

 subtuberculato, angulis humeralibus distinctis, fere rectis. Femora minus fortiter 

 clavata, tarsorum anticorum lobis parvis. Abdominis segmentum primum ventrale 

 grosse et sat crebre punctatum. Rostrum % breve, vix longius quam latius, fortiter 

 longitudinaliter rugosum. ^ %. Long. 2'2 — 3"2 mm. 



Allied to P. blackburni but quite distinct by its depressed or flattened form, 

 less numerous erect setae, &c. 



Hab. Oahu. Koolau range behind Waialua. A single example (var. diversus), 

 taken in the same range near Honolulu, has the elytra less flattened, the thorax strongly 

 transverse, and the erect setae of the elytra decidedly shorter. It will probably prove 

 to be a distinct species. The typical form lives beneath the bark of Straussia.
