OF NEW ZEALAND. 1481 



broad ; its sides slightly, the posterior angles much rounded ; its 

 punctures large, sometimes confluent, finer beyond the centre, more 

 or less rugose. Elytra scarcely broader than the thorax at the 

 base, not twice its length, shoulders slightly narrowed, their sides 

 nearly straight, narrowed behind ; they are almost striate-punctate, 

 but appear transversely rugose. Legs robust; tibia slightly flexuous, 

 the hind pair, along their inner face, distinctly serrate, their inner 

 extremity more prolonged than the others. 



Underside obscure-red, more or less evidently punctate, with 

 depressed yellowish setae ; prosternum transversely impressed in 

 front ; mctasternum with a transverse elevation on the middle ; 

 abdomen slightly raised between the hind coxae, third and fourth 

 segments not very short, second somewhat flattened in the middle, 

 its frontal suture distinct. 



Length (rost. incl.), If lines ; breadth, nearly % line. 



Mount Pirongia. Two examples, brought amongst leaf-mould by 

 Mr. A. T. Urquhart. 



Plotnus. 



Nov. gen. 



The species for which this genus is proposed resembles Nestrius 

 serripes more than any other, but some structural details necessitate 

 the generic separation of the two species. 



The rostrum is shorter and more arched above, and, moreover, it 

 is depressed, or pinched in, near the eyes. The scrobe is shallow 7 

 behind, it extends to the eye, and occupies the whole side of the 

 rostrum. The eyes are small and rotundate. The scape bears 

 slender setae, it reaches just beyond the front of the thorax, it is 

 thick, but not much thicker near the extremity than it is at the 

 base. The first joint of the funiculus is nearly twice the length of 

 the second, the third and fourth are longer than broad ; the club is 

 broadly oval, pilose, and evidently articulated. The tarsi are fur- 

 nished with long, prominent hairs. The apex of the rostrum pre- 

 sents a good distinguishing character ; it is smooth, and marked off 

 by a fine suture so as to appear like the genus Clypeorhynchns. 



2560. P. ovithorax, ?&$ Subopaque, fusco-testaceous, the 

 rostrum and thorax dull-obscure-reddish, the antennae and tarsi 

 reddish ; it is sparselj 7 clothed with small, depressed, yellowish 

 setae, and some longer, erect, pale ones. 



Thorax longer than broad, oviform, its sides slightl} 7 and evenly 

 rounded ; its surface a little unlevel, with shallow, irregular, fovei- 

 form impressions. Elytra closely striate-punctate. 



Antenna inserted near the apex of the rostrum. Prosternum 

 with a broad furrow (transversal) near the front. Abdomen with 

 fine brassy scales. 



Length (rost. incl.), 1^ lines ; breadth, nearly f line. 



Capleston. One example, found by Mr. Cavell.
