OF NEW ZEALAND. 467 



Thorax elongate, cylindrical, a little contracted anteriorly, with sub- 

 parallel sides, base sinuous with a central lobe ; its surface is closely 

 and very finely punctulate. 



The elytra are wider than the thorax at the base, more so posteriorly, 

 yet not greatly distended ; their sculpture consists of coarsely punctured 

 striae, the interstices being scarcely as wide as the striae and somewhat 

 convex. 



Legs ferruginous, long and stout ; the femora are inflated but 

 scarcely dentate .; tibiae straight ; tarsi stout, infuscate. Scutellum 

 distinct. 



Length, ij line (rost. inch). 



I found this species at Tairua, on the foliage of Metrosideros 

 tomentosa. 



Group RHINOMACERJD^E. 



Under-mentum with a broad neck of variable length. Mandibles 

 slender, sometimes lamelliform and somewhat prominent, simple at 

 apex. Head short or rather elongate, in the latter case cylindrical : 

 rostrum often long, slender, and dilated anteriorly; its median scrobes 

 generally linear, superficial, and attaining the base. Antenna straight 

 (not geniculate); funiculus seven-jointed; club elongate and more or 

 less laxly articulated. Eyes rather large and prominent. Prothorax 

 without ocular lobes, not hollowed in front or below. Elytra leaving 

 (or not) the pygidium exposed. Front coxa moderately prominent ; the 

 intermediate contiguous or separated by the mesosternal projection ; 

 tibia unarmed at apex, their corbels small, terminal and open ; tarsal 

 claws bifid or free. Abdominal segments free; projecting intercoxal 

 process very short, acutely triangular. Episterna of the metathorax 

 variable. Mesothoracic epimera moderate.

Differs from Diodyrhynchus thus : Maxillary palpi prominent, 

 slender. Labrum distinct, transversely quadrate. Rostrum more robust, 

 a little longer than the head, enlarged at the end. Antennal club more 

 elongate, its two first joints obconical. Thorax longer than broad, 

 moderately convex, a little rounded laterally, truncated at base and 

 apex. Elytra a little more elongate. 



829. R. rufula, n.s. Rufous, moderately shining, pilose, antennae 

 and legs fulvous. Antenna inserted at the middle of the rostrum, 

 moderately stout, eight-jointed, club three-jointed ; the two basal joints 

 are of nearly equal length, and, together, nearly half as long as the rest 

 conjointly; third and fourth elongate, each a little shorter than the 

 fifth ; sixth to eighth about equal ; the club is loosely articulated, its 

 basal joint somewhat cup-shaped, second largest, sub-quadrate, apical
