624 FAUNA HAWAIIENSIS 



(22) Mirosternns c/eniidafiis, sp. nov. 



Niger, subnitidus, pronoto subtilissime punctato et pallide pubescente, M. siiuplici 

 simillimus, sed elytris ad suturam baud impressis, ibique baud densissime punctulatis et 

 pubescentibus distinguendus. 



I have seen but two examples of this species, probably females, since the club 

 joints of the antennae are not at all large. Both have been badly damaged by unskilled 

 mounting. The punctures near the suture of the elytra are not so small as usual, quite 

 different from the dense and e.xcessively minute ones of other allied species, though 

 towards the ape.x of the elytra they become denser and finer and there the surface 

 becomes pubescent. The extreme basal margin is also more or less closely punctate 

 and pubescent.

{23) Mirosternus latifrons, sp. nov. 



M. siniplici simillimus, niger, nitidus, pronoto pallide pubescente, elytris ex majore 

 parte fere glabris, parce subseriatim punctatis, suturam juxta et ad marginem basalem 

 densissime punctulatis, ibique pubescentibus. Antennarum clava magna, articulo primo 

 late triangulari, apice fortiter producto, angulo interno acuto. Oculi latissime separati. 

 Metasternum antice fortiter carinatum. Long. 2"2 mm. 



I have seen only one e.xample of this minute species. It may prove to be the 

 male of M. simplex. 



Hab. Oahu. 



(24) Mirostermis piisillus, sp. nov. 



Niger, nitidus, pallide pubescens. Oculi baud magni, latissime separati. Anten- 

 narum clava (^) magna, articulo primo late triangulari, angulo interno fortiter acuto, 

 secundo sat lato, margine apicali et margine interno fere aequilongis. Pronotum minus 

 dense pubescens. Elytra ex magna parte perparce (nee subtilissime) punctata, parum 

 pubescentia, parte apicali minutissime punctulata et minus dense pallido-pubescente, 

 basi summa subtiliter vix sparsim punctata, sutura apicem versus sat fortiter impressa. 

 Metasternum antice planum, fortiter carinatum. Long. 2 '2 mm. 



I have seen only one e.xample of this species.
