1 86 FAUNA HAWAIIENSIS 



setisque erectis et elongatis vestita, fortiter punctata, humeris productis. Abdominis 

 segmentum primum ventrale, vel ad medium, grosse fortiterque punctatum. Z ?• 



Long. 3—475 mm. 



A species of wide and somewhat depressed form, rather scantily clothed with 

 squamosity, forming in fresh examples a number of roundish spots on the elytra, which 

 also bear pale erect setae. The scape of the antennae is not long, being evidently 

 shorter than the two following joints united. Second joint evidently longer than wide, 

 but very much shorter than the third. All the other joints elongate, the 8th shorter 

 than the gth, the latter with the two following forming the long and slender club. Eyes 

 large and prominent. Thorax usually strongly and abruptly constricted in front, but 

 variable in this respect. In front there is a deep and conspicuous impression, and 

 sometimes two lateral, and one posterior (near the hind-margin about the middle) 

 as well, but all except the anterior one may be obsolete. The posterior angles of the 

 thorax are very clearly marked, being covered with a spot of dense pale squamosity. 

 Elytra wide, roughly punctured, generally more or less flattened, the sides somewhat 

 strongly rounded, the shoulders prominent. Lobes of the front tarsi only moderate in 

 size, or even small for the size of the insect. Whole body beneath coarsely and closely 

 punctured. 



Hab. Kauai, widely distributed and not rare (2500 — 4000 ft.). Remarkable for 

 its dark colour, wide form, the distinct spots of squamosity on the posterior angles of 

 the thorax, and the clothing of the elytra, which consists of long fine erect setae, and 

 numerous, often rather ill-defined, spots of appressed scales. 



(4) Proterhinus eugonias, sp. nov. 



Sat latus, nigricans, piceus, vel rufescens, pallide squamosus. Antennae graciles, 

 clava sat evidenter 3-articulata. Oculi parum fortiter prominentes. Pronotum profunde 

 3-impressum. Elytra sat lata, convexa, parte basali depressa, minus fortiter nee dense 

 punctata, pallide squamosa, setisque erectis parce vestita, humeris late ac fortissime 

 productis. Segmentum abdominis primum (saltern ad medium) vix evidenter punctatum. 

 ^ %. Long. 2 — 3-5 mm. (Plate IX. fig. 2, ?.) 



This species is allied to P. basalis Sh. It varies greatly in size but is a smaller 

 insect than the other. The form is wide and somewhat short, the colour varies from 

 black to red. The squamous covering is of a golden or silvery colour. 



Antennae moderately long, slender, generally clear red with the apical joints dark, 

 the club distinctly formed of three joints but rather slender and elongate. Eyes 

 moderately large, but not at all strongly prominent ; no ridge between the vertex and 

 front of head. Thorax with three very deep impressions, the anterior the largest; 

 immediately in front of each of the posterior ones the squamosity forms a dense patch,
