COLEOPTERA 223 



2-articulata. Pronotum latum, antice abrupte constrictum, densissime punctatum, im- 

 pressionibus posterioribus absentibus, linea longitudinal! squamositatis densae utrinque 

 notatum, caetera parte parce squamosa, setis curvatis sat distinctis lateraliter vestitum. 

 Femora parum fortiter clavata. Elytra irregulariter albido-squamosa, baud inaequalia, 

 setis perpaucis erectis albidis inconspicue vestita, basim versus sat fortiter angustata, 

 humeris acutis. Rostrum % gracile, fortius elongatum, basim versus evidenter angus- 

 tatum. %. Long. 2 '5 mm. 



This species is perhaps the most closely allied to P. oscidans, having the 

 rostrum of the % of very similar form, elongate and widening towards the ape.x, and also 

 very similar antennae. The general aspect of the two is very different, the abundant 

 short erect setae, which form the chief portion of the clothing in P. oscidans, being 

 almost absent in the present species, and there are numerous other distinctions. The 

 basal abdominal segment beneath closely and strongly punctured at the sides. 



Hab. Maui, lao valley. A single % example taken. 



(78) ProterJdiius vdrabilis, sp. nov. 



Nigricans, tibiis, lobisque tarsorum, rufescentibus. Caput post oculos subcon- 

 strictum, oculis fortiter prominentibus. Antennae elongatae, vix graciles, articulo 

 primo fortiter clavato et elongato, secundo robusto, longiore quam latiore, tertio 

 quartoque elongatis, lateribus fere parallelis, clavae 3-articulatae articulo basali 

 longiore et evidenter latiore quam articulus octavus. Pronotum profunde 3-impressum, 

 antice fortiter angustatum, pallide (latera versus densissime) squamosum. Femora 

 antice fortissime incrassata, lobis tarsorum latis et permagnis. Elytra maculatim 

 squamosa, setisque erectis albidis parcius vestita, rugoso-punctata, subaequaliter con- 

 vexa, basi scutellum juxta utrinque tuberculata, humeris productis. ^. Long, vix 

 4 mm. (Plate IX. fig. 22.) 



A somewhat large species, with the lobes of the front tarsi very strongly developed. 

 The antennae are also remarkable, the basal joints being elongate but stouter than usual, 

 the first long and strongly clavate, the next two or three nearly parallel sided, whereas 

 the two or three preceding the club are short and of triangular shape. The three 

 terminal joints form a distinct club, the 9th joint being considerably wider at the apex 

 than the preceding. The head is constricted behind the eyes, an obscure ridge being 

 formed between the front and the vertex. The thorax is wide across the middle, but 

 very strongly and abruptly narrowed in front, the two posterior impressions are very 

 deep, roundish, and small, the front one wide and vague, but deepened at the middle. 

 The pale squamosity towards the sides is very dense. The elytra have no really 

 definite longitudinal ridges, but are nearly evenly convex, tuberculate on either side
