888 COLEOPTERA 



longer than thorax, considerably narrowed towards the base ; sutural 

 grooves distinct, those between them and the shoulders composed of 

 two well-marked punctures, the hinder elongated. Hind-body much 

 longer than elytra, gradually depressed posteriorly, hirsute. Legs 

 moderately slender, tibiae but little curved, tarsi moderately 

 short. 



In S. sulcator and S. osculans the wing-cases are similarly 

 narrowed towards the front, but these two are distinguishable in 

 other ways ; the latter, however, makes the nearest approach to the 

 present species so far as regards the intra-humeral impressions. In 

 all the other species the elytra are oblong, narrowed before the 

 middle only, or else more or less obtusely rounded at the sides. 



Length, i-|- lines ; breadth, nearly f . 



Unique. Found near Whangarei Harbour. 



1581. S. dnplicata, ^^-s. Shining, head and thorax pitchy-red, 

 antenuce red, elytra and legs of a paler hue, reddish, abdomen rufo- 

 castaneous. 



Head small, considerably narrower behind, frontal sulcus large, 

 basal fovese obsolete or quite absent. Antennce thick aiid elongate, 

 basal joint rather short and stout, second and third sub-globular, the 

 latter nearly equalling the former ; fourth longer than broad, oviform ; 

 joints 5-g sub-quadrate ; tenth transverse, eleventh conical. Palpi 

 elongate and rather slender. Prothorax a good deal, but obtusely, 

 dilated at the middle, so as to appear much narrowed in front and 

 behind, with the usual sculpture. Elytra larger than thorax, sub- 

 oblong, slightly narrowed towards the shoulders ; sutural striae of 

 equal depth and breadth throughout, intra-humeral depressions 

 with a separate basal puncture ; between the two grooves on 

 each elytron there is an abbreviated punctated stria with raised 

 margins. Hind-body larger than elytra ; basal segment with minute 

 depressed scales, its apex fringed with finer hairs than those on the 

 others ; posterior segments deflexecl. Legs moderate ; tibiaB a little 

 arcuated on the outside, none bent ; tarsi not elongate. 



The head is narrower behind than in any other species (its hind 

 angles quite obsolete), the back part being but little broader than the 

 neck. The punctated stria between the sutural groove and the 

 intra-humeral depression is quite exceptional.

One example. Parua, near Whangarei Harbour. 



1582. S. tenuis, "-s. Slender, shining, testaceous, with grey- 

 ish pubescence, legs and palpi yellow. 



Head small, a little dilated but rounded behind, frontal cavity 

 shoi-t, hind foveas rather elongate, antennal tubercles small and but 

 little elevated; not convex. Antenuce elongate, third and fifth arti- 

 culations smaller tlian the contiguous ones, ninth and tenth trans- 

 verse and larger than the preceding ones. Prothorax ovate-cordate, 

 impressed in the orthodox fashion. Elytra hardly longer but 

 broader than thorax, narrowed towards the front, sutural stride not 

 very deep, the intra-humeral elongate. Hind-body longer but not
