COLEOPTERA 621 



are perhaps rather less developed and this is a smaller and darker insect. It greatly 

 resembles some examples of J/, i/tuticiis, but the large eyes separate it. The metasternal 

 carina is obsolete. 



Hab. Lanai. 



(14) Mirostcniiis blackbttrni, sp. nov. 



Niger, pronoto dense punctato, pubescentia grisea plus minus aureo-tincta vestito. 

 Oculi maris magnitudine mediocres, latissime separati. Antennarum maris articuli 

 3 ultimi magni, horum primo intus sat acute angulato, latere apicali fortiter concavo sive 

 emarginato. Antennae teminales mediocriter magnae. Elytra albida sive cinerea pubes- 

 centia appressim vestita, post media maculam pulchram pubescentiae aureae densam 

 utrinque terentia, his maculis fasciam, ad suturam valde angustatarr, formantibus, parte 

 longa apicali basique summa densissime punctatis, plaga intermedia fere glabra, niti- 

 dissima, sparsissime punctata, sulcis longitudinalibus obsoletis faciliter distinguendis, 

 sutura elevatula. Metasternum ^ antice fortiter carinatum. Long. 2-3 — 3 mm. 



Cannot be confused with any other species except the following, which is perhaps 

 hardly more than a local race. The antennae in these species sometimes have the 

 club joints yellow. 



Hab. Oahu ; Waianae mountains, 2000 ft. or more ; five specimens. 



(15) MirostcrmLS blackbnrnioides, sp. nov. 



M. blackburni affinis et persimilis, sed pubescentia elytrorum aurea fasciam latam 

 formante, multo latius suturam attingente, et plagam multo majorem elytrorum postice 

 tegente. 



Hab. Oahu ; common in the Honolulu range ; easily distinguished, when in good 

 condition, but often abraded. 



(16) jMirostermis affiiiis, sp. nov. 



Niger, nitidus, pronoto subtilissime punctato, pubescentia pallida vestitus. Oculi 

 latissime distantes. Maris antennarum clava magna, articulo primo et secundo tri- 

 angularibus, apicibus sat fortiter productis. Clava antennarum feminalis quam in mare 

 multo minor. Elytra juxta suturam utrinque dense subtilissime punctata, parte caetera 

 fere glabra, subseriatim et minus subtiliter, obsoletius, parce punctata, longitudinaliter 

 obsolete sulcata. Long. 2-5 — 3-25 mm.
