suture and a lateral streak on each elytron, and the scutellum, 

 are rufous; legs and antennae testaceous. 



Head convex between the eyes, nearly smooth there j 

 clypeus with raised margins, its sculpture rugose-punctate, 

 but rather shallow. Thorax transverse, widely emarginate 

 at apex ; base bisinuate, "with rectangular angles ; anterior 

 angles subacute ; the sides are indistinctly angulate before 

 the middle, gradually narrowed anteriorly, ne irly straight 

 behind ; the base, therefore, is rather wider than the front ; 

 the surface is almost smooth and polished; the sides bear a 

 few grey setae similar to those on the legs. Elytra oblong, 

 apices rounded, their sides gently curved, shoulders obtuse ; 

 they are punctate-striate, the outer striae, however, are 

 shallow or obsolete; interstices nearly plane, with a few 

 minute distant punctures. Underside infuscate, rather 

 sparingly clothed with white setae. 



Legs elongate, the hinder pairs of tibiae bicalcarate at 

 apex. Antenna sparsely hispid: basal joint clavate at. 

 extremity ; 2nd also stout, subglobular, 3i d slightly longer 

 than 4th, each of these nearly twice as long as broad ; 5th 

 broad but very short, thicker at one part than the other; 

 club feebly pubescent.

Ophir. Amongst the sands of the Manuherikia River. 



Six specimens, both sexes, discovered recently by Mr. J. H, 

 Lewis. 



Prodontria, gen. nov. 



Body convex, subovate^ nearly nude. Clypeus with re- 

 flex(-d margins, obtusely rounded, its basal suture nearly 

 straight, the front face perpendicular. Labrum horizontal, 

 deeply notched, so that the outer lobes appear prominent. 

 Palpi rather short, their terminal joints elongate ; the labial 

 apparently invisible. Antenna inserted just below and in 

 front of the eyes, 8-articulate ; basal joint clavate, as long 

 as the following three conjointly, these three hardly twice as 

 long as broad ; the four terminal leaflets are elongate and 

 minutely pubescent. Thorax strongly transverse, deeply 

 incurved in front, bisinuate at base, distinctly marginated. 

 Scutellum large, rounded. Elytra convex, broadly oval, 

 marginated, truncate at extremity. Pygidium exposed, 

 vertical, rounded. Tibia nude, the anterior tridentate ex- 

 ternally ; the other pairs with spiniform setae, the apical 

 rims semicircular, truncate and subserrate, and with short 

 coarse ciliae. Tarsi elongate, 5-jointed, claws simple.
