COLEOPTERA 197 



(24) Proterhinns homocochronnts, sp. nov. 



P. eiii'hopalo forma et colore simillimus, sed paullo major, et antennis longioribus, 

 clava paullo minus abrupta, capite inter oculos latiore distinguendus. ^ %. Long. 

 2 — 2'6 mm. 



Very closely allied to P. cur/iopahis, but a rather larger species with decidedly 

 longer antennae, and the club less marked, owing to its basal joint being less short and 

 wide. The head is also decidedly wider between the eyes in the present species. 



Hab. Kauai, above Waimea (4000 ft.). 



(25) ProterJiinus cogJiatus, sp. nov. 



Elongatus, angustus, rufescens, capite obscurato, elytris utrinque nigro- vel fusco- 

 notatis. Antennae graciles elongatae, articulis omnibus sat elongatis, clava gracili, haud 

 abrupta. Pronotum subelongatum, antice angustatum. Elytra angusta, pallide squamosa, 

 setisque nonnullis erectis perinconspicue vestita, basi leviter emarginata. Species forma, 

 colore, et caeteris, P. homoeocJironw simillimus, sed paullo major, et antennis evidenter 

 gracilioribus et magis elongatis, clava minus distincta, distinguenda. ^ $. Long. 

 2"6 mm. 



Very closely allied to P. homoeochronius but of larger average size, the antennae 

 elongate and very slender, the club decidedly more slender and less definite. 



The five species described above form a very remarkable series ; and although all 

 were obtained from only a very small area of the island of Kauai, excepting perhaps 

 the two Halemanu species, no two were found in the same locality. It is probable 

 however that P. serricorms and P. laticornis were not actually obtained together, since 

 two very distinct districts were collected over at Halemanu, and it is more than likely 

 that each of these regions had its peculiar species. It may also be observed that the 

 two species taken in the mountains behind Waimea occurred at different altitudes. 



Hab. Kauai, mountains above Waimea (3000 ft.). 



(26) Proterhinus angusti/ormis, sp. nov. 



Angustus, fortiter elongatus, plus minusve rufescens, pallide squamosus, elytris 

 nigro-maculatis. Antennae graciles, articulis basalibus rufis, clava vi.x 3-articulata, 

 articulis duobus apicalibus praecedenti multo majoribus. Oculi minores parum fortiter 

 prominentes. Pronotum minus latum, pallide squamosum, lateribus minus fortiter
