634 FAUNA HAWAIIENSIS 



(48) Mirosternus mtiticus Sharp. 



Mirostcrmis viidicus Sharp, Tr. Ent. Soc. London, 1881, p. 523. 



This species is very abundant on Hawaii and no doubt is common on Maui, 

 though I did not take many specimens there. It varies in size, colour and puncturation. 

 The eyes are large, but rather widely separated even in the Z- 



Hab. Maui, Hawaii. — Maui, Haleakala ; Hawaii, widely distributed (4000 — 

 5000 ft.). 



(49) Mirosternus discolor, sp. nov. 



Colore variabilis, fusco-niger, castaneus, aut nigro-castaneus, capite cum pronoto 

 saepe elytris pallidiore, subnitidus, parcius pallide pubescens. Oculi magni, singulis ac 

 frontis spatium intermedium fere aeque latis. Antennarum clava sat magna, plerumque 

 brunnea aut rufescens, articulo primo triangulari, fortiter dilatato, angulo interno baud 

 acuto, apice fortiter producto. Pronotum subtilissime indistincte punctulatum, pallide 

 pubescens. Elytra subnitida, baud dense pubescentia, puncturatione indistincta et plus 

 minus obsoleta, male definita. Long. 3 — 3'5 mm. 



This is an obscure species but not difficult to recognize, having the eyes of large 

 size and the elytral puncturation feeble. In fresh examples the pubescence is most 

 noticeable along the sutural portion of the elytra, where the puncturation is usually 

 close and very fine. Beyond this there is a good deal of very fine surface rugulosity 

 and the punctures are remote and feeble. The puncturation varies considerably. I am 

 not able to be sure as to the sexes in this species.

(50) Mirosternus inarginatus, sp. nov. 



Ferrugineus sive rufo-brunneus, pronoto sordidiore, sat dense pubescentia pallida 

 flavescente vestitus. Oculi magni, sed late separati, singulis spatio frontis intermedio 

 evidenter minus latis. Antennarum clava magna, articulis 2 basalibus quodam in 

 aspectu quasi quadrangularibus. Pronotum subtilissime minus distincte punctatum, bene 

 pubescentia vestitum. Elytra subaequaliter subtiliter punctata, et pubescentia, 

 marginibus obscurioribus aut plus minus nigricantibus, sutura apicem versus fortiter 

 impressa. Metasternum anterius planum et fortiter carinatum. Long. 3*25 mm. 



Superficially like M. ociilafus &c., but with much smaller eyes, which are much 

 more widely separated.
