COLEOPTERA 193 



(16) Proterliimts an/iqinis, sp. nov. 



Rufescens vel rufo-fuscus, angustus, elongatulus, elytris nonnunquam nigro- 

 maculatis, setis appressis albidis vel argenteis, aliisque erectis sat conspicuis, sed 

 brevioribus, vestitis. Antennae plerumque breviores. Oculi minuti. Pronotum setis 

 appressis, aliisque erectis, vestitum, baud latum. Elytra angusta, elongata, lateribus 

 saepe fere parallelis, plus minusve irregulariter argenteo- vel albido-squamosa, setisque 

 erectis brevioribus conspicue vestita, parum conspicue inaequalia. Rostrum $ brevissi- 

 mum, sulcis longitudinalibus sat fortibus. $ $. Long. 2 — 275 mm. 



Allied to P. blackburni Sh , but distinguished by the white or silvery appressed 

 setae which cover parts of the elytra, the narrower form, shorter erect setae, etc. 



Hab. Kauai mountains (4000 ft.); a few examples were taken on several 

 occasions. 



(17) Proterhinus setiger, sp. nov. 



Rufescens vel rufo-piceus, setis erectis sat crebre vestitus, statura majore. Antennae 

 graciles, articulo secundo subelongato. Oculi prominuli. Pronotum antice abrupte 

 angustatum, setis erectis vestitum, baud squamosum, grosse denseque punctatum, 

 lateribus baud rotundatis. Elytra baud squamosa, setis erectis perconspicue vestita, 

 inaequalia, lineis longitudinalibus elevatis setis appressis pallidis vestitis, grosse 

 punctata, basi arcuatim sat fortiter emarginata, humeris acute productis, lateribus parum 

 rotundatis. Rostrum % evidenter longius quam latius, longitudinaliter fortiter rugosum, 

 lateribus basim versus levissime convergentibus. ^ ?. Long, vix 4 mm. 



A much larger species than P. blackburni, to which it is evidently allied. I have 

 seen only one $ and one female, and the former has the prominent lateral angles 

 of the prothorax, which are formed by its sudden constriction in front, much more 

 strongly developed than those of the latter, and the puncturation more distinct. Each 

 wing-case has three raised dorsal lines, one extending back from the humeral angles, 

 another from the basal tubercles on either side of the scutellum, while between these on 

 each side is a third elevation which does not however reach to the basal margin of 

 the elytra. In the % the basal abdominal segment beneath is less coarsely punctate 

 than the very coarsely and closely punctured metasternum ; the apical segments are 

 impunctate or nearly so. 



Hab. Kauai (4000 ft.) ; i t and i % taken. 



(18) Proterhinus solitariiis, sp. nov. 



Piceus, setis erectis ex majore parte vestitus, baud squamosus, statura majore, baud 

 robustus. Oculi minuti. Antennae graciles, articulo secundo elongato, subclavato. 

 Pronotum antice abrupte angustatum et impressum, dense rugoso-punctatum. Elytra
