COLEOPTERA 641 



also another in which the basal joint of the club of the antennae is less elongate, wider 

 in proportion to its length. I suspect these belong to the above species and the one 

 with the wider club joint may be the other sex. 



This species somewhat resembles M. vestittis, but that has smoother pubescence 

 and larger eyes. 



Hab. Oahu, Waianae mountains; Honolulu mountains (.•*), Koebele. 



(67) Mirosfernus stenarthrus, sp. nov. 



Niger, dense ubique punctatus, dense cinereo-pubescens. Oculi minores, latissime 

 separati. Antennarum clava angustior, articulo primo elongato. minus fortiter dilatato, 

 angulo interno hand acuto. Pronotum distincte, subfortiter, ubique dense punctatum. 

 Elytra dense, subaequaliter, distincte punctata, lateribus humeros juxta nitidis, ruguloso- 

 punctatis. Long. 3 — 3 "5 mm. 



There are two examples of this species, which I have marked as J and $, but it is 

 not stated that they were taken in cop. If they truly represent the sexes, then these 

 must be extremely similar in this species. The comparatively strong and distinct 

 puncturation of the pronotum is characteristic of the species and will greatly facilitate 

 its determination as also the basal antennal joint, which is longer than usual in propor- 

 tion to its width. 



Hab. Oahu, Honolulu mountains. 



(68) Mirosfernus diniidiatus, sp. nov. 



Nigricans, dense pubescentia pallida flavescenti vestitus, elytris crebre punctatis. 

 Oculi minores, latissime separati. Antennarum clava mediocriter magna, articulo primo 

 fortius elongato, minus fortiter dilatato, angulo interno baud acuto. Pronotum subti- 

 lissime indistincte punctatum, dense pubescens. Elytra dense subtilissime punctata, 

 lateribus versus humeros nitidis, parce punctatis, punctis majoribus, subobsoletis. 

 Long. 2"5 — 275 mm. 



In most respects very like M. stenaythnts, but much less in bulk, and at once 

 distinguished by the feebleness of the pronotal puncturation. The pubescence of the 

 elytra is rather rough, being directed in different directions. Only two specimens have 

 been examined which agree very closely in all respects, and the se.x cannot be 

 determined without dissection. 



Hab. Oahu, Honolulu mountains.
