6i8 FAUNA HAWAIIENSIS 



(5) Mirostcrmis pyrophihis, sp. nov. 



Praecedentibus simillimus, ferrugineus, flavido-pubescens, antennalis clavae articu- 

 lorum I et 2 angulo interne sat acuto facile distinguendus. Long. 3-5 mm. 



Apical side of basal club joint a little irregular or sinuate, its inner angle conse- 

 quently appearing somewhat produced, the following joint with this angle quite sharp. 

 Elytra more or less densely pubescent along the suture and there densely and finely 

 punctured, external to this with larger and more remote punctures and the surface more 

 rugulose, at the sides shining, longitudinally rugulo.se and with sparse punctures or 

 impunctate, the sculpture of the elytra showing some variation. The space between 

 the eyes varies in width, but whether this is sexual is uncertain. Each of these is as 

 wide or wider than the least frontal space between them. 



Hab. Hawaii, Kilauea, two examples. 



(6) Mirostcrnns basalis, sp. nov. 



Testaceus, capite et pronoto picescentibus, plaga elytrorum basali subtriangulari 

 marginibusque nigricantibus. Pronotum subopacum, densissime subtiliter punctatum, 

 dense pubescens. Elytra juxta marginem basalem suturamque et in parte apicali dense 

 punctata, partibus caeteris remote minus subtiliter punctatis, et parum pubescentibus. 

 Long. 3 7 mm. 



General appearance and form of the several preceding species, but distinct by its 

 colour and sculpture. The antennal club is largely developed, but the first and second 

 joints have the inner angle rounded off and quite blunt. Metasternum carinate, apical 

 joint of antennae very long and narrow. Sex uncertain. 



Hab. Maui, Haleakala, 4000 ft. 



(7) Mirosternns sordidus, sp. nov. 



Nigricans aut piceoniger, pallide pubescens, oculis permagnis. Pronotum indis- 

 tincte, subtilissime punctatum. Antennalis clavae articulus basalis triangularis, latere 

 interno quam latus apicale evidenter breviore. Elytra densius distincte punctata, sat 

 aequaliter pallide pubescentia. Long. 3"5 mm. 



Quite unlike all the preceding in general appearance, owing to its dark colour, but 

 with similar enormous development of the eyes. The elytra are rather strongly punc- 

 tured, and the basal club joint of the antennae is remarkable, the side between the base 

 and the inner angle being considerably shorter than the side between this angle and the 

 apex. The latter side also is slightly irregular or sinuate. The metasternum is flat in 

 front and strongly carinate. 



Hab. Kauai ; apparently rare.
