COLEOPTERA 62 



o 



(19) Mirosternits montanus, sp. nov. 



Niger, piceus aut rufopiceus, sat nitidus. Pronotum trans basim subtilissime dense 

 punctatum et pubescens, antice sparsius pubescens, puncturatione vix discernenda. 

 Oculi mediocres, latissime distantes. Antennarum clava mediocriter magna, articulo 

 primo minus fortiter dilatato. Elytra nitida fere glabra, circum suturam dense, subti- 

 lissime, obscure, sive obsoletim punctulata, ibique subtiliter pallide pubescentia, parte 

 caetera subtilissime longitudinaliter rugulosa et sparsissime obsolete punctata. Meta- 

 sternum haud aut obscurissime carinatum. Long. 2 '5 — 3 mm. 



The sexes apparently do not differ greatly in the development of the club joints of 

 the antennae, or else the ten examples are of the same sex and the individuals rather 

 variable. What I consider to be males have the club joints of only moderate size. 



Hab. Kauai ; various localities. 



(20) IMirosfernus nigipciuiis, sp. nov. 



Niger, nitidus, pronoto plus minus pallide pubescente, elytris glabris. Oculi $ 

 mediocres, latissime distantes. Antennarum clava $ magna, articulo primo acute intus 

 angulato, latere apicali concavo sive emarginato, angulo apicali sat producto. Clava 

 feminalis maris multo minor, sed angulo interno articuli primi sat acuto. Pronotum 

 posterius dense, subtilissime, antice vix evidenter punctatum. Elytra sparsissime (non- 

 nunquam vix evidenter) punctulata, longitudinaliter subregulariter subtiliter sulcata, 

 suturam juxta haud lineam dense punctulatam praebentia. Metasternum $ parum 

 concavum, sed posterius sulcatum, antice carina elongata et distincta praeditum. 

 Metasternum % sat fortiter concavum, carina obsoleta aut absente. Long. 2 — y^ mm. 



Hab. Hawaii ; Mauna Loa, about 3000 ft. 



(21) Mirostejnuts simplex, sp. nov. 



Niger aut piceus, nitidus, pronoto minus dense pallide pubescente. Oculi % (Pet ^) 

 minores, latissime separati. Antennarum clava % (Pet '$) haud magna, angulo articuli 

 primi interno et secundi haudquaquam acuto. Pronotum subtilissime puncturatum, 

 nitidum, minus dense pubescens. Elytra nitida, fere glabra, juxta suturam angustissime 

 impressa sive deplanata, ibique subtilissime punctulata et brevissime pallido-pubescentia, 

 basi extrema a scutello ad humeros hoc niodo vestita et punctulata, caeteris partibus 

 sparsissime punctatis, vi.x aut haud rugulosis. Long. 2*4 mm. 



Hab. Hawaii, Kona, 3000 ft. I have seen two examples, one of which is a little 

 immature and is a female ; the other is probably of the same sex. It is black and has 

 been badly damaged by unskilled mounting.
