2i6 FAUNA HAWAIIENSIS 



pallidis elongatis sat conspicue vestita, humeris fortiter productis. Tibiae anticae 

 graciles, elongatae ; femora omnia fortiter incrassata, lobis tarsorum anticorum minimis. 

 cT. Long. 3 mm. (Plate IX. fig. 20 and 20a. rf".) 



This remarkable species is very distinct from any other. The antennae are long 

 and slender, concolorous with the legs, of a clear rufotestaceous colour. The basal 

 joint is elongate but rather stout, all the rest are elongate and slender, as also is the dis- 

 tinctly 3-jointed club. Prothorax very abruptly constricted, and transversely impressed 

 in front, the impression deeper about the middle. The two posterior sublateral impres- 

 sions are also distinct, and behind these the middle part of the thorax is seen (especially 

 in lateral view) to be somewhat strongly elevated, the elevation subsulcate. All the 

 femora are strongly incrassate, the front tibiae unusually long and slender, the lobes of 

 the front tarsi excessively small for the size of the insect. Elytra subparallel-sided for 

 their basal half with pale squamosity, and conspicuous, very fine, erect, pale setae. 

 Seen from the side they are somewhat compressed laterally, to form the rather obscure 

 longitudinal ridges. Their humeral angles are strongly produced. 



A female taken in the same locality as the c/ no doubt belongs to the same 

 species, although at first sight of very different appearance. The antennae are formed 

 like those of the <?, the eyes are smaller but more prominent. Rostrum short, not 

 nearly twice as long as wide, the surface entirely rugulose. The whole insect is 

 blackish, except the reddish tibiae and tarsi and the greater part of the antennae, the 

 club-joints being obscure in colour. The prothorax is less elevated posteriorly than 

 that of the ^, and the elevated portion is not evidently sulcate. The elytra are a good 

 deal longer, entirely black, the sides nearly parallel except at the ape.x. Femora 

 strongly clavate as in the Z, the front tibiae also long, and the lobes of the tarsi small. 



Hab. Maui, Haleakala (4000 ft.) ; rare, only one <S and one % having been taken. 



(66) Protei'hinus megalotarsiis, sp. nov. 



Nigricans, elytris rufescentibus vel piceis, pedibus antennisque saepe plus minusve 

 rufescentibus. Oculi sat magni, subconici, fortiter prominentes. Antennae mediocres, 

 clava distincte 3-articulata. Pronotum pallide squamosum, profunde 3-impressum, vix 

 latum (feminae elongatum), lateribus rotundatis. Femora ^ fortiter incrassata, lobis 

 tarsorum anticorum magnis. Elytra pallide squamosa, setisque gracilibus erectis sat 

 conspicue vestita, fortius (nee inaequaliter) convexa, sutura subelevata, humeris fortiter 

 acute productis. ^ $. Long. 2-8 — 3-25 mm. 



A rather distinct species, at least in the ^, but apparently variable, the antennae 

 being a good deal shorter, in some examples than in others. There is no distinct ridge 

 between the vertex and front of the head in either sex. The eyes are large, very
