from the basal fovea, and nearly attaining the apex, besides the rather 

 deep marginal channel ; the basal fossie are almost connected by an irregu- 

 larly formed impression, while the curved frontal impression extends 

 nearly across the thorax ; the disc itself, owing to these depressions, 

 appears convex, and is finely striated transversely. The e/y^ra are ovi- 

 form, with fine, reflexed margins, slightly sinuated near the apices, the 

 latter divaricate and rounded ; each elytron has a short scutellar, and seven 

 strise, these latter bear rather large but shallow punctures, and the sides 

 are punctate ; the interstices are simple and a little elevated, the fifth is 

 insulated by the confluence of the fourth and sixth, and these again by 

 the third and seventh. The /egs are long, the farsi elongate, the first 

 four joints superficially grooved and carinated and brush-like below.

I have named this fine species in honour of its discoverer, T. F. 

 Cheeseman, Esq., F.L.S. I have only seen one mutilated specimen 

 which was found by him at Remuera, Auckland. 



58. A. (Platynus) SUlcitarsiS, f'.s. A rather elongate, convex 

 insect, somewhat glossy black in colour, with pitchy-red legs, and reddish 

 antennsB, palpi, and tarsi ; the latter (anterior) have an elongate basal 

 joint, the second and third are triangular, the fourth sub-cordate, and 

 all are widely grooved above, so that the middle of each joint is a good 

 deal carinated ; the joints of the posterior are more sharply grooved and 

 ridged. The //an/ is oval, constricted behind, with a large, hispid 

 puncture near the base of each jaw, a transverse line in front unites the 

 very indistinct frontal impressions, and the rest is nearly smooth. J^/v- 

 thorax much longer than broad, ovate-cordate, narrower than the elytra, 

 convex, base and apex subtruncate ; it is rounded anteriorly and later- 

 ally, and narrowed behind, the width of the front and base about equal, 

 the posterior angles are not acute ; the median line does not reach the 

 apex, the basal foveas are large but not deep, with a curved impression 

 from each proceeding towards the front ; the marginal channel is not 

 continued to the hind angle, so that the surface, at that point, is level 

 with the rim, and the surface is finely strigose. The elytra are elongate- 

 oval, slightly sinuated and narrowed behind, slightly convex, with 

 sharply-marked, impunctate strife, the sixth and seventh are prolonged 

 towards the suture ; the interstices are a little elevated, the seventh 

 bears two punctures at the apex, and the marginal punctures are inter- 

 rupted, and coarsest behind.

I found one mutilated specimen at Parua, near Whangarei Harbour. 

 The species is quite distinct, dissimilar to the foregoing, and, perhaps, 

 not a true Auc/uvncnus.
