128 COLEOPTERA 



Long. Corp., 2^ mm. 



Mas. Antennis lo-articulatis, articulis duobus ultimis extus concavis ; 

 trochanteribus anterioribus spina tenui elongata armatis ; abdomine 

 segmento 2° ventrali ante apicem processis tenuibus duobus leviter 

 recurvis insigne. 



^ Antenniz longer than head and thorax, first joint scarcely so long 

 as the two following together ; fifth joint longer but scarcely stouter 

 than the contiguous ones ; eighth joint small, scarcely so large as the 

 seventh ; ninth joint large, cut away on one side, so as to leave the 

 apical portion prominent on that side ; eleventh joint large, much 

 broader in one direction than in the other, and with one of the two 

 broad faces impressed or concave. Head with the front much depressed 

 in the middle, and the vertex with two large fovete. Thorax much 

 narrower than the elytra, about as long as broad, the sides dilated a 

 little in front of the middle, and on each side there is an indistinct fovea 

 behind the dilated part. Elytra much longer than the thorax, with a 

 deep and distinct sutural stria, but without other impressions. Legs 

 long, and rather slender. 



The whole of the upper surface is shining and impunctate, and bears 

 some long, fine hairs. 



I have received five specimens, all males, of this species, taken at 

 Auckland, from Mr. Edwards. 



Note. — I found a ii^.^^ individuals, of both sexes, at Tairua. In the 

 female the penultimate joint is larger than its predecessor, and the last 

 joint of the antenn* is ovate. 



235. B. impressifrons, n.s. Somewhat similar to the female of 

 B. dispar ; being of a shining red colour, the head and ventral segments 

 darkest, the palpi and apical joints of the antennae a little infuscate. 

 AntenncE longer than head and thorax, ten-jointed ; their basal joint 

 stout, much longer and broader than second ; third and fourth equal, 

 smaller than second : fifth a little broader, and two times longer than 

 fourth, as long but not so stout as the first ; sixth as broad as but a good 

 deal shorter than fifth ; seventh and eighth about as wide as sixth, 

 transverse, the eighth only about half the length of the sixth ; ninth 

 moderately large, about as long as broad, its internal apex produced in 

 the form of a stout claw-shaped spine ; tenth joint larger than ninth, 

 broadly oval ; the last six joints are covered with very short pubescence, 

 so as to render them dull and rough. Head nearly as wide as thorax, 

 with a broad but not very deep impression extending from the front to 

 behind the eyes, this depression is divided into two distinct parts by a 

 carinated interval between the eyes, and the lateral space behind the 

 eye is also depressed. Prothorax a little longer than broad, a good 

 deal narrowed and rounded anteriorly, with a sinuation towards the 

 base, so that it seems to be somewhat dilated laterally at the middle ; 

 it is convex and uneven, there being a large, somewhat curved depres- 

 sion at each side behind the middle, almost confluent towards the 

 dorsal line, and extending towards the front ; these impressions are 

 irregular in form. The elytra are convex, rather long, wider than
