1046 COLEOPTERA 



1870. B. decens, n.s. Shining, nearly glabrous ; dark- 

 red, elytra paler, legs chestnut-red, tarsi and palpi yellow. 



Head broadly impressed in front, not distinctly foveate there, 

 with two small foveae on the vertex. Thorax widest behind the 

 middle, unimpressed. Elytra moderately large, the sides rounded, 

 widest behind the middle, with distinct sutural striae. Hind-body 

 deflexed, not distinctly pubescent. Legs elongate and slender ; 

 posterior tibiae flexuous. 



Underside reddish, with some fine hairs. Metasternum with a 

 broad shallow impression behind. Basal segment of abdomen 

 bituberculate, the tubercles bearing erect, slender, yellow setae. 



Antenna moderately elongate ; second joint narrow and shorter 

 than the first ; fifth distinctly longer than the third or fourth; sixth 

 and seventh nearly equal, as broad as the fifth, but shorter ; eighth 

 small, subquadrate; ninth joint large, abruptly incrassate, its basal 

 portion, at one side, where it is articulated to the preceding one, not 

 half the width of the larger part ; this is subquadrate, with its inner 

 angle impressed and rectangular ; the apex, at the other side, has a 

 small spiniform process ; tenth joint nearly as large as the ninth, its 

 extremity rounded, and with an angular prominence near the side. 



The form of the two terminal joints of the antennae will enable 

 entomologists to identify it. 



$ . Length, -| ; breadth, quite line. 



Paparoa, near Howick. Two males. 



1871. B. munroi, n.s. Impunctate, shining, red, head and 

 thorax darkest, tarsi fulvous ; clothed with elongate conspicuous 

 hairs. 



Head uneven, the sides broadly raised, the interval depressed, 

 owing to the fovese appearing confluent, the interocular foveae well 

 marked. Thorax widest before the middle, each side with a fossa- 

 like contraction behind. Elytra ample, somewhat curved laterally, 

 sutural striae fine but distinct. Legs elongate ; posterior tibia a 

 little bent near the extremity ; basal articulation of hind tarsi armed 

 with an elongate, spiniform, slender process extending more than 

 half-way along the second joint. Underside pubescent. 



Male. Antenna hirsute, 10-articulate ; basal joint longest, 

 cylindric ; second and third joints longer than broad ; fourth rather 

 shorter than these ; fifth nearly twice the length of fourth ; sixth 

 shorter than the preceding one ; seventh almost quadrate ; eighth 

 transverse ; ninth largest, nearly obconical, not exactly truncate at 

 apex, acuminate towards one side at the extremity ; tenth almost 

 rotundate, with a short, broad, terminal protuberance, hollowed out 

 underneath ; the two apical joints asperate. Prostcrnum somewhat 

 granulated on the middle. Anterior coxes armed with elongate 

 spines. Basal segment of abdomen very large, bearing a pair of 

 spiniform tubercles near its extremity; intermediate segments much 

 reduced, almost linear. 



Female. Antenna similar in structure to those of the other sex, 

 except as follows : 11-jointed ; ninth joint considerably larger than
