Broun. — New Genera and Species of Coleoptera. 393 



Head nearly quite smooth. Thorax about a fourth broader than 

 long, not perfectly smooth, having some obsolete longitudinal linear 

 impressions in front and transverse ones on the disc; the mesial sulcus 

 nearly attains the apex; there are no basal fossae, only a broad oblique 

 impression of each side near the angle; its sides are rather slightly, 

 almost regularly rounded, yet rather more straightly narrowed towards 

 the subrectangular basal angles. Elytra with well-marked impunctate 

 striae and short scutellar grooves; they are rather wider than thorax at 

 the base, and a good deal, though gradually, narrowed behind the pos- 

 terior femora, with only very slight subapical sinuosities. 



When compared with A. smithi this is seen to be narrower and 

 flatter. The front of the thorax is a little more incurved, so that its 

 angles seem more prominent, but the posterior angles are more obtuse, 

 and the base slightly emarginate medially. The elytra appear to be 

 narrower and longer, and are not at all abruptly narrowed near the 

 extremity; the dorsum is nearly Hat, but the sutural region is a little 

 elevated behind. 



$. Length, 8 mm. ; breadth, 2 1 - mm. 



Forty-mile Bush, near Napier. A single female, under the number 

 352, from Mr. H. Suter, had to be set aside for many years until the 

 recent discovery of the male of A. smithi.

 Coleopt., p. 1327. 



Oblong-oval, gradually narrowed anteriorly, slightly convex, mode- 

 rately shining, piceo-niger; legs, mandibles, and labrum pitchy red, the 

 antennae, palpi, and tarsi paler. 



Head narrower than thorax, smooth, frontal impressions quite obso- 

 lete. Thorax incurved at apex, with obtuse angles, the width at the 

 base nearly a third more than the length in the middle; its sides dis- 

 tinctly margined, nearly straight for two-thirds of the length, being 

 only very slightly and gradually narrowed anteriorly, but near the 

 front rather more curvedly contracted ; base medially emarginate and 

 resting on the elytra, with obtusely rectangular angles; the mesial groove 

 starts from the basal margin but does not reach the apex, basal impres- 

 sions feeble and elongate, placed between the middle and sides. Scutel- 

 lum triangular. Elytra scarcely any broader than the thorax at the 

 base, humeral angles thickened and projecting outwardly, only very 

 slightly, however; they are a little wider at and behind the middle, and 

 considerably though not abruptly narrowed near the extremity; their 

 striae are simple, narrow, and sharply marked throughout, and become 

 deeper behind; interstices broad and plane; marginal punctures almost 

 absent near the middle. 



There is a single setigerous puncture at each side of the thorax before 

 the middle, and another at each hind angle, a pair alongside each eye 

 and on the edge of the forehead, and twice that number at the extremity 

 of the last ventral segment. 



Antennae thickly covered with yellow pubescence, and a few slender 

 setae, from the 4th joint onwards, the basal three glabrous; they extend 

 backAvards to the shoulders. Labrum transverse. Palpi with acuminate 

 terminal articulations. Eyes moderately large, but not prominent. Legs 

 robust; tibiae with spiniform setae externally, the posterior flexuous.
