234 FAUNA HAWAIIENSIS 



(99) Proterhinus heterotarsus, sp. nov. 



Nigricans, elytris rufis plus minusve nigro- vel fusco-notatis, tibiis, tarsis, antennis- 

 que plerumque rufis, his apicem versus nigricantibus. Antennae graciles, clava distincte 

 3-articulata. Pronotum aequaliter minus dense squamosum, minus fortiter 3-impressum, 

 globosum, lateribus fortiter rotundatis. Elytra griseo-squamosa, setisque erectis pallidis 

 conspersim vestita, basi emarginata, humeris productis et acutis. Femora sat incrassata ; 

 tarsorum anticorum articulus secundus brevissimus, fortiter transversus, lobis brevibus. 

 Species praecedenti simillima. ^ %. Long. 2 — 27 mm. 



Apparently closely allied to the preceding species (/". angnsiior), but generally of 

 less narrow form, and with the thorax more globose, the antennae rather longer and 

 more slender, and the elytra more nearly covered with squamosity, the dark markings 

 being reduced. The variation of both species makes it difficult to distinguish the two 

 in description, but the tarsi appear to be constantly different in form, the lobes of the 

 second joint of the front pair being in this species extremely short, and the whole joint 

 very small and strongly transverse, while the rostrum of the $ is nearly parallel-sided, 

 not gradually but slightly narrowed to the apex. The extent to which the humeral 

 angles of the elytra are produced is decidedly variable. 



Hab. Molokai, mountains (3000 ft.) ; only six or seven examples taken. 



(100) Proterhinus erythrodes, sp. nov. 



Minor, rufescens, totus fere aequaliter pallido-squamosus, elytris nonnunquam 

 fusco- vel nigro-notatis. Antennae graciles, elongatae, clava distincte 3-articulata, 

 rubricolores, nonnunquam articulis apicalibus nigricantibus. Oculi minores, parum 

 prominentes. Pronotum globosum, parum distincte impressum, aequaliter pallide 

 squamosum, lateribus fortiter rotundatis. Elytra pallide squamosa, setisque nonnullis 

 pallidis erectis parum conspicue vestita, aequaliter convexa, basi leviter emarginata, 

 humeris distinctis, sed vix acutis vel productis. Femora omnia cum tibiis tarsisque 

 rufescentia (rarius obscurata), lobis tarsorum anticorum minutis. ^ %. Long, i '6 — 

 2'5 mm. 



A small and obscure species, without any striking characters. The antennae are 

 rather long and quite slender, with a distinctly 3-jointed apical club ; they are often 

 entirely of a clear red colour, but the apical joints are sometimes more or less dark. 

 The colour of the insect is red, that of the thorax being sometimes more or less 

 obscured, as also is the head, and the elytra often have some dark markings. The 

 squamous covering is evenly distributed over the greater part of the surface. The 

 elytra at the base are lightly emarginate, but the humeral angles are hardly produced, or 

 distinctly acute. The eyes are small and the lobes of the front tarsi minute. 



Hab. Molokai, mountains (3000 ft.) ; only nine examples of this species were 

 taken.
