658 FAUNA HAWAIIENSIS 



Proterhinus adehis van chrysadelns var. nov. 

 Thorax and elytra evenly and similarly clothed all over with golden or greyish- 

 golden squamosity, the whole insect reddish, except for some fuscous spots on the 

 elytra, these spots being free from the appressed clothing. Antennae red at the base, 

 dark apically. Thorax depressed in front and narrowed, sometimes more abruptly 

 constricted, the posterior impressions faint or absent. Erect setae on elytra fine, white, 

 long and conspicuous. 



Proterhinus adehis var. coustricticeps var. nov. 



Head strongly transversely constricted behind the eyes. In other respects appa- 

 rently not differing from some other specimens of P. adehts, some of which also show 

 a tendency to constriction. 



Hab. Oahu ; this variable species occurs throughout the Koolau range. 



{2) Proterhinus maurtts, sp. nov. 



Magnitudine grandi, robustus, niger, lobis tarsorum piceis aut obscure testaceis. 

 Antennae subrobustae sed fortius elongatae, clava distincte 3-articulata ; oculi permagni 

 et fortiter j^rominentes. Pronotum parum squamosum, setis curvatis conspicue vestitum, 

 antice fortiter impressum, post medium utrinque fortiter rotundatim foveatum, postice 

 ad medium impressum, angulis posterioribus prominulis et macula albida ornatum. 

 Elytra fusco-setosa, utrinque juxta scutellum ad basim tuberculata, post media setis 

 albis bisignata, pergrosse punctata, parum squamosa, angulis humeralibus fere rectis. 

 Long, circiter 5 mm. 



A most distinct species which cannot be confused with any other of the genus. 



Hab. Oahu; Koolau range, 1800 ft. On Pelea. 



(3) Proterhinus echidna, sp. nov. 



Rufescens aut ferrugineus, elytris mediis utrinque nigro- vel fusco-notatis, anten- 

 narum clava nonnunquam obscuriore. Minus dense aureo- vel griseo-squamosus, elytris 

 pedibusque setis gracillimis et perelongatis vestitis. Antennae graciles, elongatae, 

 clava distincte 3-articulata, oculis prominentibus, magnitudine mediocribus. Pronotum 

 antice fortissime impressum. Elytra latiuscula, lateribus rotundatis, angulis humeralibus 

 acutis. Long. 2 — 3*25 mm. 



A very distinct species by the extremely long, fine setae of the elytra and legs, the 

 red colour of almost the whole insect, the deep thoracic impression and the shape of 

 the elytra. Like other species of the genus, it varies in the development of the 

 antennae, eyes, &c. 



Hab. Oahu ; mountains near Honolulu on Gotildia.
