636 FAUNA HAWAII ENSIS 



(54) Mirosternits aniaiirodes, sp. no\'. 



Niger, antennis fere nigris, tibiis nigris, femoribus anterioribus rufis. Oculi 

 magnitudine mediocres, latissinie separati. Antennarum clava J magna, articulo primo 

 fortiter dilatato, angulo interno haudquaquam acuto, apice fortiter producto. Elytra 

 dense subtiliter punctata. Long. 3 '2 5 mm. 



I have seen two males only of this species, both entirely denuded of pubescence, 

 and one much mutilated by unskilled mounting. It is very similar to M. solitariiis of 

 Oahu, but the eyes of that species are so much larger, it is impossible to treat them as 

 belonging to one species. 



Hab. Hawaii, Kona, 3000 ft., in the wet belt. 



(55) Mirostcrnus plebcius, sp. nov. 



Nigricans, fusco-niger aut piceus, capite (et nonnunquam pronoto) elytris saepe 

 pallidiore, pallida (cinerea aut flavescente) pubescentia vestitus. Oculi magnitudine 

 mediocres, aut minores, latissime separati. Antennarum clava ^ sat magna, articulis i et 

 2 fortiter dilatatis, angulis internis haud acutis. Pronotum nitidum, ex majore parte vix 

 evidenter punctatum. Elytra crebre plus minus obsolete punctata, puncturatione plus 

 minus rugulosa, lateribus nitidis rugulosis, parce punctatis, punctis versus humeros 

 perpaucis. Metasternum carinatum. Long. 2"]^ — 3"25 mm. 



This species is best recognized by the elytral puncturation, which is dense and of 

 an indefinite character, the punctures tending to run into one another, and making the 

 surface rugulose. The antennae of the female are small, much less developed than in 

 the ^, the eyes are remote and not at all large in either sex. There is some variation 

 in the intensity of the puncturation. In both sexes the metasternum is carinate, the 

 carina in the $ longer than that of the female. 



Hab. Hawaii, Kilauea. 



(56) Mirosternus elongattilus, sp. nov. 



Brunneus aut fusco-niger, pubescentia flavescente crebre vestitus, forma sat elongata. 

 Oculi mediocres, late separati. x-\ntennarum clava magna, articulo primo triangulari, 

 fortiter dilatato, apice (necnon etiam secundi) fortiter producto, angulo interno acuto aut 

 saltem parum obtuso. Elytra densius aequaliter pubescentia, crebre punctata, lateribus 

 humeros juxta nitidis, parce punctatis. Long. 3 — 3-5 mm. 



Except that one example is black or nearly so, the three examples agree very well 

 in most respects. Though everywhere dense on the dorsal surface, the puncturation of 

 the elytra becomes still more dense and minute on the apical part. It is also dense 

 along the lateral margins except towards the shoulders. The legs and two basal joints
