62 2 FAUNA HAWAIIENSIS 



M. ajjiiiis var. stitiiralis nov. 



Praecedenti simillimus, elytrorum parte dense punctata et pubescente posterius 

 latiore distinguendus. 



Hab. Kauai, Oahu, Molokai. — Kauai (var. sttturalis) one example ; Molokai ; 

 3000 ft., three specimens. 



(17) Mirosternus sculptus, sp. nov. 



Castaneus, plus minus nigrotinctus, elytris apices versus pallidioribus. Antennae 

 (Psexus) mediocres, clava mediocri, articulo primo multo longiore quam latiore, latere 

 apicali leviter concavo sive emarginato, apice evidenter, sed parum fortiter producto. 

 Oculi mediocres, latissime separati. Pronotum dense flava sive aurea pubescentia 

 obtectum, subtilissime et ad medium remote punctatum. Elytra ex magna parte fere 

 glabra, nitida, parum punctata, longitudinaliter fortiter canaliculata sive rugosa, basi 

 extrema, apicebusque longe, densissime punctatis et conspicue pubescentibus. Long. 

 2 '5 mm. 



The sex of the unique example is uncertain. The longitudinal grooves on the 

 glabrous portion of the elytra are nearly regular almost to the suture, where the sculpture 

 becomes more ordinarily rugose. 



Hab. Oahu, a single specimen in the mountains behind Waimea, 2000 ft. 



(18) Mirosternus varicolor, sp. nov. 



Nitidus, rufescens, capite pronotoque plus minusve obscuratis aut nigricantibus, 

 elytrorum parte media plus minusve nigricante aut obscurata, antennarum clava nigra. 

 Oculi mediocriter magni, late distantes. Antennarum ^ clava magna, articuli primi 

 angulo interno baud acuto. Pronotum dense subtiliter punctatum, pallide pubescens. 

 Elytra ad basim extremam necnon in parte apicali dense et subtilissime punctata et 

 pallide pubescentia, parte intermedia fere glabra, sparsissime punctata, punctis his 

 majoribus. Long. 2 '5 mm. 



This little species varies in colour and may be either rufescent with more or less of 

 the middle part of the elytra dark, or black with the red of the elytra forming a spot on 

 each side at the base and an apical pale area. 



Three males were captured .in the same spot and a single female, which no doubt 

 belongs to the same species, was taken with them. This has the antennae much wider 

 apart, the head and pronotum paler, the intermediate portion of the elytra less smooth, 

 being a little more punctured and with fine but rather conspicuous rugulosity of the 

 surface. 



Hab. Molokai ; on the lower edge of the forest above Kaunakakai.
