1010 COLEOPTEEA 



top of the hind slope, and are rather feebly impressed there, the 

 punctuation becomes less distinct behind the middle ; the third in- 

 terstices with two punctures. Tibice rather slender ; basal joint of 

 front tarsi oblong, and, like the second, not strongly produced at 

 the inner extremity. 



The insect is subopaque. The contraction of the thorax behind 

 the middle is rather abrupt, somewhat similar to what may be seen 

 in the genus Metacjlymma.

Manawatu Eiver, near Palmerstou. One male, found by Mr. 

 G. V. Hudson. 



1810. B. tersatum, n-i^- Suboblong, somewhat depressed, 

 shining, chestnut-red or fulvescent, the legs and two basal articu- 

 lations of the anteunee yellowish, the other joints infuscate, elytra 

 sometimes with fuscous marks. 



Head with elongate frontal impressions, and distinct interocular 

 punctures with long, yellow sette. Mandibles elongate, curvate at 

 apex only. Eyes prominent. Penultimate joint of maxillary j;aZj;i 

 large, somewhat rounded at one side, infuscate, densely pubescent ; 

 terminal joint minute, scarcely perceptible. Prothorax transverse, 

 broadest before the middle, strongly rounded, a good deal sinuate 

 behind; basal angles acute, rectangular, somewhat prominent, disc 

 slightly convex, median groove rather fine, basal foveee small, close to 

 the angles ; near the basal margin there is a transverse depression, 

 which has a row of punctures ; lateral margins well developed, the 

 basal distinct from the angles as far as half-way to the middle. 

 Elytra oblong, broader than thorax, humeral angles rounded, the 

 sides a little curved, not distinctly sinuated behind ; the punctate 

 sutural stria extends from the base and recurves at the apex, forming 

 a distinct curvate carina directed forwards nearly in line with the 

 third interstice, but the punctuation ceases near the hind slope ; there 

 are two other punctate stride which scarcely reach the hind thighs, 

 and do not touch the basal margin ; beyond these are two series of 

 moderately large punctures, not extending as far back as the second 

 and third striae, the external row, indeed, has only six or eight 

 punctures ; near the basal margin there are two large round im- 

 pressions. Front legs robust, the others rather slender ; hind tarsi 

 with elongate joints.
