COLEOPTERA (^^^j 



of the antennae are red in all the specimens, the club joints black, the intermediate 

 joints red in two and dark in the other example. I should think all three are certainly 

 males and I do not know the other sex. The elytra are unusually elongate. 



Hab. Maui, Haleakala, about 4000 ft. 



(57) Mirosternus tetragotius, sp. nov. 



Niger, tusco-pubescens, elytris dense punctatis, antennarum articulo secundo rufo, 

 tibiis nigricantibus. Caput subtiliter punctatum, oculis mediocribus, latissime separatis. 

 Antennarum clava magna, articulo basali subquadrangulari, apice fortiter producto, 

 articulo secundo triangulari, apice fortiter producto. Elytra ex majore parte aequaliter 

 crebre punctata, fusco-pubescentia, lateribus fere ad humeros dense punctatis, sutura 

 postice impressa. Metasternum anterius fortiter carinatum. Long. 275 mm. 



The single e.xample is no doubt a male and is easily distinguished by the antennae 

 and sculpture. The puncturation of the pronotum appears to be very indistinct, much 

 more so than that of the head.

(58) Mirosternus rufcsccns, sp. nov. 



Rufescens, capite obscuriore, pronoto antice, elytrorum lateribus, sutura, anten- 

 narumque clava nigricantibus, pallide pubescens. Oculi magnitudine mediocres, latissime 

 separati. Antennarum clava magna, articulo primo quodam in aspectu quasi sub- 

 quadrangulari, apice fortiter producto. Pronotum subtiliter vix dense sat evidenter 

 punctatum. Elytra pubescentia pallida flavescente vestita, apices versus usque ad 

 margines laterales densissime et subtilissime punctata sive sculpturata, ad basim et 

 juxta suturam subtiliter sat crebre punctata, caetera parte minus dense punctata. 

 Long. 2 '5 mm. 



The single e.xample is no doubt a male, the antennal club being well developed. 

 The first joint of this club in certain aspects has an almost subquadrangular appearance, 

 part of the inner margin appearing to be nearly parallel to the outer. This character 

 with the colour, sculpture of thora.x and elytra &c. distinguish the species. 



Hab. Maui, Haleakala, about 5000 ft. 



(59) Mirosternus dubiosus, sp. no\'. 



Nigricans, pronoto picescente, pubescentia flavescente vestitus. Oculi minores, 

 latissime separati. Antennarum clava sat magna, articulo primo quasi quadrangulari, 

 vix latissime dilatato, apice fortius producto. Pronotum densius pubescens, vix nitidum, 

 crebre ubique (sed indistincte) minutissime punctulatum. Elytra supra dense punctata 

 et pubescentia, latera versus nitida, fere glabra, longitudinaliter rugulosa, parce (nee
