Genera and Species of New Zealand Coleoptera. 43 



forehead there are five, some fine punctures occur behind 

 and six larger ones on the labrum ; close to each eye there 

 is a large puncture Avith duplicate setse ; the vertex is smooth. 

 Mandibles stout, elongate, striate. Ei/es moderately pro- 

 minent. Antennse short, their basal four joints glabrous. 

 Thorax hardly any broader than long, its sides gently 

 rounded, sinuously narrowed behind, posterior angles not at 

 all projecting, lateral margins crenulate ; dorsal groove very 

 distinct and almost touching the basal and apical margins, 

 its surface is almost quite smooth, though a few fine 

 abbreviated striae may be seen near the front and base, 

 basal fovese deep and close to the angles. Elytra oviform, 

 gradually but considerably narrowed posteriorly, the shoul- 

 ders, though somewhat narrowed, are evidently broader 

 than the base of the thorax ; their sculpture consists of 

 rather deep, quite impunctate strise, which become confluent 

 towards the extremity ; the three interstices, on each, 

 nearest the suture are nearly plane, the others are convex, 

 on the seventh there is one puncture just behind the middle 

 thigh and two or three along the stria outside, the raised 

 space parallel with the side is very smooth, and the common 

 punctiform sculpture of the marginal channel is nearly 

 altogether absent, kuieviov femora moderately inflated, the 

 outer angle of the tibia prolonged, basal four joints of the 

 tarsus with prominent external angles ; intermediate tibiie 

 scabrous, with slightly produced outer extremity, the 

 posterior simple. 



Underside shining black ; the head with close undulating 

 sculpture, flanks of prosternum closely punctate ; abdomen 

 with fine irregular linear impressions, the apex of the 

 terminal segment has tlu-ee setigerous punctures on eacli 

 side of the middle, but the usual pair of punctures on the 

 central portion is wanting. 



There is no need for comparison with other species in this 

 instance, as the deep regular impunctate elytral strise will 

 at once lead to its recognition.
