Genera and Species of New Zealand Coleoptera. 4^\ 



forehead there are five, some fine pimcturcs occur behind 

 and six larjicr oiies on the hihrmu ; close to caeli eye tlicre 

 is a hir^^c puncture with duplicate sctjc ; the vertex is smooth. 

 Mandihics stout, clonj^atc, striate. Ei/cs moderately pro- 

 minent. Antennie short, their basal lour joints glabrous. 

 Thorax hardly any broader than long, its sides gently 

 rounded, sinuously narrowed beliind, posterior angles not at 

 all projecting, lati-ral margins erenulate ; dorsal groove very 

 distinct and ahnost touching the basal and apical margins, 

 its surface is almost tjuite smooth, though a few fine 

 abbreviated stri;e may be seen near the front and base, 

 basal foveie deep and close to the angles. Ehjtra oviform, 

 gradually but considerably narrowed posteriorly, the shoul- 

 ders, thoiigh somewhat narrowed, are evidently broader 

 than the base of the thorax ; their sculpture consists of 

 rather deep, quite impunetate striic, which become conHucnt 

 towards the extremity; the three interstices, on each, 

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

 on tlie seventh there is one puncture just behind the middle 

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

 sj)ace parallel w ith the side is very smooth, and the comnu)u 

 punctiform sculpture of the marginal channel is nearly 

 altogether absent. Anterior /(!'/;ior« moderately infiated, 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 l)lack ; the head with close undulating 

 sculpture, flanks of j)rosternum closely punctate ; abdomen 

 with fine irregular linear impressions, the apex of the 

 terminal segnu-nt has three sctigerous punctures on each 

 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 impunetate elytral slriic \\\\\ 

 at once lead to its recognition.
