 their third and fourth joints less oviform.

I found several examples amongst decaying Nikau trees in the neigh- 

 bourhood of Whangarei Harbour. The species will, most likely, become 

 the type of a new genus. 



169. G. fuscicorne, n.s. Head rounded, black and shining, 

 somewhat rufescent in front, seemingly free from any kind of sculpture, 

 though punctulated near the eyes. Prothorax a little larger than the 

 head, a little broader than long, finely margined, rounded anteriorly, 

 and slightly narrowed behind ; it is densely punctulated, obsoletely 

 impressed at the base and along the middle, less shining than the head 

 and browner in colour. Elytra as long as, but broader than, thorax, 

 moderately tri-sinuated behind ; they are finely punctulate, distinctly 

 clothed with greyish hairs, dark red in colour, the sides and sutural 

 space blackish, and a little shining. The hind-body is elongate, sparingly 

 punctulate and pubescent, shining blackish brown, but paler at the 

 extremity. Legs yellowish. 



This insect has very much the appearance of the female form of 

 G. cornigera, but the antennse differ materially, being moderately long 

 and rather robust, their three basal joints elongate and about equal to 

 one another, joints four to ten short and of nearly the same quadrate shape, 

 the eleventh ovate and shorter than the preceding two ; they are obscure 

 fuscous or blackish, except the two shining castaneous basal joints, and 

 the eleventh, which is paler in colour than the tenth.

I found one individual only, near Whangarei Heads, 



170. G. ruflpenne, «.i'- Antennce elongate, very gradually and 

 shghtly thickened towards the extremity ; their three basal joints 

 elongate, about equal, second cylindric, third somewhat obconical and 

 nearly twice the length of the fourth, tenth transverse, eleventh ovate, 

 much longer than the preceding one ; the two first joints are reddish 

 and shinmg, the others black. Head shining, black or reddish, quite as 

 broad as the thorax, rounded ; its middle part smooth, elsewhere finely 

 punctured, and bearing a few fine hairs. Prothorax hardly longer than 

 broad, finely margined, obtusely rounded at the base, narrowed pos- 

 teriorly, more or less evidently channelled at the base, finely punctured, 

 and sparingly clothed with yellowish hairs ; its colour very similar to 

 that of the head. Scutelluin punctate. Elytra not longer but broader 

 than the thorax, red, and notwithstanding its pubescence rather shining, 

 sinuated near each hind angle, punctulate. Abdomcti elongate, of a 

 glossy brownish black, the two last segments castaneous ; the four basal 

 segments are depressed at the base, the fourth least so, and bear a row 

 of punctures in the depressions, the rest of its surface is remotely punc- 

 tulated with fine hairs proceeding from the punctures, but much more 

 densely clothed with yellowish hairs beyond and below the lateral 

 margins. Legs moderately long, castaneous-red, clothed with fine yellow
