OF NEW ZEALAND. T2Q 



thorax, their base and apex truncate, the sides a little rounded, the 

 shoulders are narrowed: they are smooth and shining, quite impunctate; 

 but with the usual sutural striae, and a slight humeral elevation. Hind- 

 body deflexed, its basal segment rather large. The intermediate tibia 

 are slightly flexuose, and a little excised inwardly near the apex ; the 

 hind pair are a little dilated near the apex, and at that point distinctly 

 bent inwards ; tarsi yellow.

Described from one example which I found at Tairua. 



236. B. mundus, n.s. This insect is allied to B. micans and 

 impar, being less elongate than the former, and with a longer thorax 

 than the latter, but more nearly approaching it in the structure of the 

 antenna, which are finely pilose and ten-jointed ; the basal joint is 

 cylindric, longer and much stouter than the second, which is larger than 

 the third ; third and fourth equal ; fifth to eighth of equal breadth, a 

 little broader than fourth, the eighth very short ; ninth large, conspicu- 

 ous, nearly obconical, not much longer than broad, almost truncate at 

 apex ; the tenth joined to ninth by means of a very short, slender 

 stalk, of the same breadth as its predecessor, but longer, oblong, 

 obtusely rounded. Head nearly as broad as thorax, antennal tubercles 

 very indistinct, with two elongate fovese between them, and two others 

 on the vertex. Prothorax convex, a little longer than broad, dilated 

 laterally in the middle, rounded anteriorly, and sinuously narrowed 

 behind ; its surface is quite smooth and shining. Elytra longer and 

 wider than thorax, narrowed towards the shoulders ; each elytron with a 

 sutural stria, the rest of the surface unimpressed. Pygidium deflexed 

 and pubescent. Legs pubescent, the two hind pairs of tibiae flexuose. 



The insect is of a shining red colour, the head, thorax and elytra are 

 quite nude. 



In thefema/e, the basal antennal joint is not appreciably broader 

 than the second, the ninth joint is not quite so large, and is obliquely 

 truncated at apex ; the frontal fovese are less obvious, and the body is of 

 a darker colour. 



Length, f line. 



I found five specimens at Tairua. 



237. B. crassicomis, n.s. Somewhat similar to B. micans in 

 general outline, of a dark shining red, the legs and elytra paler. 



Antenna stout, ten-jointed, as long as head and thorax ; the two 

 basal joints stout, the second not much smaller than the first ; joints 

 three to seven become shorter and more transverse, the seventh as broad 

 as the eighth but short ; eighth large, oblong ; ninth larger than eighth, 

 sub-oblong, obliquely truncated at apex ; the tenth not so large as 

 ninth, rounded ; the seven basal joints are smooth and shining, the 

 eighth and ninth, owing to their very short pubescence, are quite dull 

 and somewhat piceous, and the last is of the same colour as the basal 

 ones, but not so bright. Head as broad as thorax, with two foveae on 

 the vertex, and the space between these and the somewhat transverse 

 antennal tubercles depressed.
