OF NEW ZEALAND. 66l 



scarcely longer than broad, much narrower than the el)ira, narrowed 

 behind and in front, but not perceptibly marked in any way. The elytra 

 are much longer and broader than the thorax, convex, rounded laterally, 

 broader behind than at the shoulders ; each with a distinct sutural stria, 

 but quite destitute of other sculpture. Hind-hody rather shorter than the 

 elytra, curvedly deflexed, rounded, finely margined, its basal segment 

 not larger than the second, in fact the first three are of nearly equal 

 size. Legs moderate, normal, tarsi elongate and slender. Antennas, robust, 

 lo-articulate, quite the length of the head and thorax; their basal joint 

 longer and stouter than the second ; joints two to four not quite equal, 

 the third obconical, more slender at the base than its predecessor; fourth 

 sub-moniliform, shortest ; fifth a good deal larger than fourth, longer than 

 broad, almost obconical ; sixth transversal, much broader than the pre- 

 ceding, and projecting inwardly ; seventh as long as sixth, narrower, 

 disposed so as to project outwardly, but only in a slight degree ; eighth 

 shorter and narrower than seventh, a little thicker on the outside than 

 elsewhere ; ninth large, nearly obconical ; tenth largest of all, obtuse- 

 ovate : the enlarged terminal joints are rather dull and rough. 



The facies of these species is similar to B. mundus, but the structure 

 of the antenniE differs from all the previously-described species.

I found one male near Whangarei Harbour. 



1 1 55. B. ignotUS, n.s. Body convex, glossy, sparsely clothed 

 with long, erect, testaceous hairs ; elytra castaneous, head, thorax, and 

 abdomen dark-red, legs pale-red, antennas slightly fulvous, tarsi and 

 palpi yellow. 



AntenncB ftot longer than head and thorax, lo-articulate ; their two 

 apical joints obviously larger than their predecessors ; the two basal joints 

 stout, sub-equal; three to four equal, slightly longer than broad, smaller 

 than fifth ; the latter oblong, rather longer than sixth ; seventh similar to 

 the fourth ; eighth shortest ; ninth broader than eighth, transverse ; tenth 

 transversal, hardly twice the width of the preceding one, largest, ovate. 

 Head hardly as broad as thorax, vertex convex ; a large pubescent fovea 

 close to each eye seems continuous with a frontal depression. Prothorax 

 convex, cordate, considerably narrowed posteriorly, with a distinct fovea at 

 each side, but without other well-marked impressions. Elytra not longer 

 than thorax, convex, rounded, and a good deal narrowed towards the base, 

 without evident sculpture, but broadly emarginated at the apex near the 

 sides. Hind-hody about as broad as but longer than the elytra, its basal 

 dorsal segment rather larger than the second. Legs stout, the posterior 

 iibicc somewhat flexuose, and produced at the extremity in the form of a 

 straight calcar, as long as the first tarsal joint. 



Allied to Nos. 228 and 229; resembling B. inflata, but smaller and 

 narrower, with shorter antennx, cordiform thorax, &c. ; but its chief 

 peculiarity consists in the abnormal structure of the hind tibia. 



Length, nearly i line ; breadth, J. 



INIy only example was found in the forest, somewhere near Whangarei 

 Harbour.
