OF NEW ZEALAND. SoQ 



coarsely punctured, the sides a little uneven, destitute of tubercles, 

 and, with the exception of a few large punctiform impressions, not 

 sculptured, but densely pubescent ; the coarser yellow hairs are 

 confined to the dorsum. Scntellum densely pubescent. Elytra 

 broader than thorax, near the base transversely punctate-rugose, 

 from thence the punctation becomes finer and less rugose, so that 

 towards the apices it is nearly obsolete ; they bear short, decumbent, 

 coarse, pallid hairs. Legs pubescent ; femora strongly clavate, id 

 est, nearly straight below but arched above. Aiitennce as long as 

 the body, their fourth joint shorter than third, the latter but little 

 shorter than fifth. 



May be readily identified by the absence of thoracic tubercles, 

 and the strongly inflated thighs.

One example in my own collection ; exact locality unknown.

Nov. gen. 



Body elongate, slightly convex, sub-opaque, sparsely pubescent. 

 Head porrected, oviform, ^vith a short muzzle. Eyes large, reniform, 

 coarsely facetted. I'dlpi of moderate length,, the terminal joint cf 

 the maxillary nearly twice as long as the penultimate, nearly securi- 

 form. AntenncB inserted on the forehead in line with the inner 

 margin of the eyes, pubescent, 1 1 -articulate ; basal joint stout, net 

 much clavate, second minute, third and fourth equal, each a little 

 longer than the first, joints 5-7 longest and about equal, the last 

 four compressed ; they are shorter than the body. Protliorax sub- 

 cylindrical, contracted near the apex, base emarginate, the sides 

 dilated just behind the middle and armed with a strong acute spine ; 

 two other equally stout, erect spines are placed on the chsc. Scu- 

 tclluni transverse, rounded behind. Elytra elongate, moderately 

 convex transversely, humeral angles obtuse, the sides a little rounded, 

 finely rnarginated ; apices individually rounded, exposing a small 

 portion of the abdomen, which, however, does not project. Legs 

 rather slender, linear, simple ; tarsi with brush-like soles, their basal 

 joint about as long as the following two united, third small, deeply 

 bilobed ; claws simple. Another coxce, prominent, sub-conical, but 

 little separated ; intermediate prominent, also somewhat cone-shaped, 

 more distant than the front pair, deeply notched; posterior furthtr 

 apart, less convex, notched and angulated. Metastcrnum short; 

 abdomen elongate, the basal segment largest, its process triangular, 

 the next four of nearly equal length. 



This genus is founded on No. 1013. The capture of a perfect 

 specimen, quite recently, on the Waitakerei Kange, near Auckland, 

 enables me to make known its characters. I have also changed the 

 specific name from " simpliceps" to "rugosus," and add a short 

 description.
