COLEOPTERA 659 



(4) Protcrhimis viyrsineus, sp. nov. 



Rufescens, pronoto saepe infuscato, sive piceo, elytris nigro-notatis. Antennae 

 longitudine mediocres, rufae, clava distincte 3-articulata. Pronotum parce squamosum, 

 setis curvatis ad latera distinctis, antice constrictum et fortiter impressum, juxta medium 

 impressionibus duabus rotundis distinctis, circa has impressiones densius squamosum. 

 Elytra submaculatim pallide squamosa, setisque perconspicuis albidis et crassiusculis 

 vestita, angulis humeralibus acutis et fortiter productis. Pedes et antennae rufi. 

 Long. 2 — 3 mm. 



The general red colour, the antennae and legs being red, the pronotum with a 

 dense patch of appressed squamosity adjoining the circular impressions, the remainder 

 being sparsely clothed, the very conspicuous erect white setae of the elytra, which have 

 the humeral angles strongly produced, distinguish the species rather easily. 



Hab. Oahu ; mountains near Honolulu, 1500 ft., on Rlyi'sinc. 



(5) Protej-hiuHS niyrsineoidcs, sp. nov. 



Extremely similar to P. inyrsincus, but the club of the antennae and sometimes 

 some of the preceding joints are black or nearly so, the posterior round impressions of 

 the pronotum are obsolete or very faint, their position being indicated by absence of 

 squamosity, the femora are more infuscate, and the erect setae of the elytra are more 

 elongate and slenderer. This insect also has a smoother appearance than the preceding. 



One of the examples is larger than the others and the joints of the antennae are, 

 as is often the case in other forms, longer and thinner than those of the smaller 

 examples. 



Hab. Oahu; Koolau range, 1500 ft., Waialua district. 



Protcrhimis angularis Sharp. 



P. angularis Sharp, huj. op. 11., p. 243. 



It is now quite clear to me that the specimens from Oahu and all the wind- 

 ward islands that I referred to P. angularis S. are quite distinct from that species. 

 P. angularis appears to be almost, if not entirely, confined to the mountains in the 

 neighbourhood of Honolulu and is not very common. It is of depressed form, the 

 elytra bear abundant and conspicuous fuscous erect setae. The antennae are always 

 moderately elongate.
