OF NEW ZEALAND. 679 



third articulations short, equal ; joints 4-10 slightly prolonged inwardly 

 at the apex, the false terminal joint distinct. 



Under-side piceous, punctate and pubescent. Metastcrnum grooved 

 throughout its whole length ; mesosternal cavity shallow behind ; inter- 

 coxal suture distinct ; coxal lamina a good deal developed near the 

 trochanter, but much decreased towards the episternum. 



Length, 7 lines ; breadth, nearly 2. 



One example in my own collection ; exact locality unknown. 



Oxylasma. 



Nov. gen. 



Epistome obtusely rounded, horizontal, its front margin distinct, but 

 not reflexed, projecting beyond the clypeus ; the latter vertical, not 

 abbreviated, widely emarginated ; the labrum on the same plane as the 

 clypeus, or, at any rate, not perceptibly different. Prosternal suture repre- 

 sented by a broad smooth line extending from the outer edge of the coxa 

 to the eye; prosternal process curved upwards between the coxae. Meso- 

 sternal cavity moderate, with thick, nearly horizontal margins. Process of 

 the metasternum rather narrow, its suture distinct. Coxal lamina strongly 

 developed over the trochanter, where it is notched ; from thence it de- 

 creases abruptly, so that before reaching the episternum it becomes quite 

 linear and acuminate. Tarsi moderate, simple, all the joints well de- 

 veloped, the penultimate smallest, entire. The antennal spaces are small, 

 concealed from above by the edge of the forehead. Eyes large and pro- 

 minent, finely but distinctly facetted. Chin-piece prominent, broadly 

 rounded. 



1185. O. pannOSUm, n.s. Body almost bare, having only ex- 

 cessively minute greyish hairs distributed over its surface, though a few 

 longer ones may be noticed on the anterior angles of the thorax ; it is 

 glossy, reddish-brown in colour, with yellow legs and antennae. 



Head closely and coarsely punctured, a good deal depressed in front. 

 Prothorax longer than broad, curvedly narrowed before the middle, 

 becoming rather broader, with a very slight sinuation, towards the pro- 

 minent divergent posterior angles ; disc convex, broadly but not deeply 

 impressed longitudinally, and also near each side ; its punctation 

 moderate, finest near the middle; slightly wrinkled on the median 

 groove. Scutellum quadrate. Elytra but little rounded laterally, punc- 

 tate-striate, the interstices rather finely and distantly punctulated, yet 

 appearing somewhat rugose ; the sculpture becomes coarser towards the 

 sides. 



Under-side castaneous, coxae yellow ; somewhat closely punctate, and 

 with longer pubescence than the upper surfaces. Legs pubescent. An- 

 tenna stout but filiform, elongate, second and third articulations short and 

 about equal, each shorter than the third. Metasternum grooved. 



The insect appears glabrous, and is broadest behind the posterior 

 femora. 



Length, 6| lines ; breadth, 2\. 



Described from one example found near Whangarei Heads.
