456 Capt. T. Broun on new 



reaching backwards to intermediate femora ; basal three 

 joints glabrous, the others pubescent, first stouter and rather 

 longer than third, second about one third shorter than the 

 following one. Thorax 1\ lines long by nearly 1^ broad, 

 widest before the middle, gradually narrowed behind, poste- 

 rior angles obtuse, apex widely incurved, base medially 

 emarginate and obliquely rounded towards each side, lateral 

 margins a little reflexed; the discoidal stria extends from 

 base to apex, the basal foss£e are large; there is a curvate 

 transverse impression in front, with some feeble longitulinal 

 stria? similar to those at the base. Elytra oblong, shoulders 

 rounded and slightly narroAved, apices oblique; they have 

 deep impunctate strife. 



There are two setae on each side of the thorax, one at the 

 bind angle and the other near the middle, and there are four 

 on the hind margin of the last ventral segment of the female. 



Male. — Anterior tarsi with three dilated basal joints, each 

 almost cordate, the first longest. Mandibles obtuse at extre- 

 mity, the right one with a small blunt tooth on the inside, 

 more evident in the other sex. 



This is the largest species known to occur here. Tiie 

 thorax is quadrate-cordate. D. subopaca and D. ovicoUis 

 have dull elytra. 



Length 5|, breadth 2g lines. 



Te Aroha. 



Three examples from Mr. J. J. Walker. 



Anchomenus Walkeri, sp. n. 



Suhdepressed, somewhat nitid, rufescent ; legs, palpi, and 

 antennee testaceous. 



IJead oviform, longer than the thorax and almost as broad 

 as that is ; two large sulciform impressions extend from the 

 occiput to the forehead, they are situated nearer to the centre 

 than they are to the eyes ; the sides, outside the deep stria 

 ■which proceeds forwards from each eye, are slightly angu- 

 lated at the point of antennal insertion ; the gen?e are broadly 

 rounded. Labrum somewhat incurved. Mandibles elongate. 

 Eyes rather small and but little prominent, distant from 

 thorax. Antennce elongate, slender, their third joint nearly 

 twice the length of the second ; they are finely pubescent, the 

 basal two joints, however, are glabrous. Thorax as long as 

 broad, widest before the middle, well rounded there, deeply 

 sinuate behind, so that the acute posterior angles appear large 

 and prominent ; the base is truncate, the ajjex emarginate; 

 the median furrow extends from the front and is a little
