481 COLEOPTERA. 



falvescent ; hiucl-body half the whole U-iigth, castaneous, covered with 

 fine decumbent yellowish hairs. 



Head shorter and slightly broader than thorax, its sides gently rounded ; 

 irregularly but distinctly jDunctured in front, almost smooth behind the 

 middle but with a row of finer punctures across the base, lateral sculpture 

 somewhat rugose ; each antennal tubercle is prolonged as a carina as far 

 back as the eyes, and there is a short stria alongside^ it. Thorax truncate 

 at base and apex, slightly longer than broad, gradually narrowed posteriorly, 

 with ^indistinct lateral margins ; along each side of the middle there is a 

 straight, deep, indefinitely quadripunctate groove which does not reach the 

 base or apex, and a pair of detached shallow punctures in front ; near each 

 side a simple groove extends from the base, it is a little curved outwardly 

 in front but does not reach the apex. Elytra nearly twice as broad as 

 long, truncate behind, curvedly narrowed towards the base, which has a 

 transverse series of small marginal punctures, the sutural striae are fine, 

 the lateral margins slender. Hind-body irregularly sculptured, basal seg- 

 mi>nt sliglitly longer than succeeding ones, fifth truncate behind, sixth 

 somewhat retracted, narrower, widely emarginate, seven tli ()])tusely tri- 

 angular, with minute yet quite definite terminal styles. 



Eyes lateral, with distinct facets, occupying more than half the length 

 of the head. Mandibles fully as long as the head, curved, slender and acute 

 towards the extremity, each with a median tooth which, though moderately 

 elongate, projects so little inwardly that it may escape notice unless 

 examined from the side. 



In D. bisulciceps (3823) the head is broadly grooved near the sides, the 

 thoracic grooves are broader and impunctate, and the middle pair, instead 

 of being straight, are bent obliquely outwards in front. D. stilbus (3037), 

 a North Island species, is smaller, the mandibles are shorter but the inner 

 tooth of each is more prominent and extends in front of the middle, and 

 the central thoracic grooves are more distant from each other near the 

 base than in front.

Elongate, subdepressed, glabrous, nitid ; black, the legs, clypeus, and 

 basal six joints of antennae castaneous, remaining joints dull fuscous and 

 densely pubescent, palpi and tarsi rufo-testaceous. 



Head, including the moderately prominent eyes, almost as broad as 

 thorax, closely and distinctly punctured near the eyes, very irregularly 

 and more distantly on the vertex, with a short broad groove along the 

 middle behind. Thorax scarcely as long as broad, finely margined, widest 

 and somewhat rounded near the middle, slightly sinuate and narrowed 

 towards the rectangular posterior angles, base and apex truncate ; with a 

 shallow central and a pair of basal impressions, the one at each side is 

 deeper and has a slight nodiform elevation in front, the disc distinctly but 

 irregularlv punctured so that some parts are nearly smooth. Elytra about 

 a fourth longer than broad at the sides, arcuate-emarginate at the extremity, 

 nearly a third longer a)id broader than thorax ; on each elytron there are
