The chin-piece is much shorter than it is in E. rufescens. 



$ . Length, 3% ', breadth, 1 j- lines. 



Dunedin (Flagstaff Hill) . One specimen; Mr. T. Chalmer. 



2015. E. obsoletus, n.s. Differs from E. punctatus as fol- 

 lows : Antennce reaching intermediate femora, third joint slightly 

 shorter than second, both, together, a little shorter than fourth. 

 Thorax slightly constricted near the anterior angles, widest near the 

 front, posterior angles more divergent. Elytra rather feebly striate, 

 especially behind, where, indeed, the striae become indistinct and 

 irregular, interstices more evidently punctate and rugose. 



$ . Length, 3-| ; breadth, 1-J lines. 



Dunedin (Flagstaff Hill). Mr. T. Chalmer ; one individual only. 

 It is a strange circumstance that four specimens, taken during one 

 day at the same place, the only members of the group that were 

 seen, should, on examination, prove to represent three distinct 

 species of an easily-recognised new genus. 



Monocrepidius. 



2016. M. maritimus, n.s. Elongate, subparallel, clothed 

 with fine yellowish hairs ; thorax and antennae rufo-testaceous, 

 elytra castaneous, legs pale-yellow. 



Head closely and finely punctured. Antennce. nearly two-thirds 

 of entire length of body ; third joint hardly longer than second, both 

 short. Thorax gradually narrowed towards the front, about as long 

 as it is broad, basal angles carinate above, somewhat divergent ; its 

 surface densely and finely punctured. Elytra distinctly punctate- 

 striate throughout, interstices finely punctate, apices individually 

 rounded. 



Underside pale-chestnut, finely punctured and pubescent. 



This rather bright-looking species is very different from M. exsid. 



$ , Length, 4J; breadth, 1J lines. 



Mokohinou Island. Mr. Sandager, who sent me two specimens, 

 informs me that they were found during October, on the ground, 

 near the sea, and that they are nocturnal and short-lived. 



Silene. 



Nov. gen. 



Forehead nearly horizontal, very obtusely curvabe, with well- 

 defined, smooth, but not raised, frontal margin, overhanging (or 

 projecting) the clypeus, which in the middle is very short, but at 

 the sides is longer. Labrum vertical, with a deep basal suture. 

 Antenna inserted in small cavities ; moderately serrate, second and 

 third joints short. Prosternum convex along the middle, with 

 well-marked oblique sutures ; broadly rounded in the middle, in 

 front, and with two transverse impressions, the one near the apex 

 the larger : its process nearly horizontal, elongate, and acuminate. 

 Mesosternal cavity narrow, deep, almost parallel-sided, extending to 

 the well-defined intercoxal suture, with narrow raised borders.
