OF NEW ZEALAND. 673 



broader than the thorax, oblong, marginated laterally, gradually rounded 

 posteriorly ; the scutellar region is depressed, their shoulders somewhat 

 elevated, and the middle of each broadly impressed ; they are punctate- 

 striate, the punctures more obvious than the striae, all more or less 

 irregular, the sutural striae being nearly obliterated at the base, and their 

 punctation ceasing behind the middle. Legs clothed nearly in the same 

 way as the body. 



Under-side blackish, densely punctulated, covered with pale yellow 

 hairs, some of which are very short; metasternum grooved longitudinally; 

 the two front pairs of coocce and the base of the femora castaneous. 



Length, if lines; breadth, \. 



We are indebted to Mr. P. Stewart, of Wellington, for the detection of 

 this species. He found it on stones in a local stream. 



Group LUC ANID^E (P. 250). 

 Dorcus (P. 251). 



1174. D. Stewarti, n.s. Body sub-depressed, oblong, obscure- 

 black, legs piceous, antennal club and palpi reddish, sparingly clothed 

 with short, erect, yellowish setae. 



Head broadly depressed in front, moderately closely and not very 

 coarsely punctured, the base and a spot in front of each eye nearly 

 smooth; eyes encroached upon by the lateral lobes, but not deeply 

 divided ; mandibles stout, tri-dentate, moderately punctured. Prothorax 

 transversal, anterior angles prominent, the middle of its apex sub-trun- 

 cate, the sides slightly rounded, broadest in front, base feebly sinuated ; 

 its whole surface more or less punctured, the punctures similar to those on 

 the head, much closer near the sides, with a large shallow impression on 

 each side of the middle. Scutellum nearly smooth, having only a few fine 

 punctures at its centre. Elytra less than twice the length of the thorax, 

 widely marginated at the base, the humeral angles not very prominent, 

 rounded behind; their punctation the same as that of the thorax, 

 becoming closer towards the sides, and on some parts of the disc 

 rather sparingly punctured, but without distinctly-raised linear spaces. 

 Anterior tibia obtusely dentate externally, the others with one median 

 tooth. Club tri-articulate. 



Under-side black, more coarsely sculptured than the upper, the back 

 and sides of the head and the sides of the abdomen with very few punc- 

 tures. 



Its comparatively small size, anterior depression of the head, and 

 sculpture of the inferior surface, &c., lead to its identification. 



Length, 5-5-! lines ; breadth, 2-2\. 



I have three mutilated specimens : one from Mr. P. Stewart, of Wel- 

 lington ; the others I found near Stoke Point, Waitemata Harbour. 



1175. D. abditUS, n.s. Oblong, sub-depressed, nude, obscure 

 black, legs rufo-piceous, tarsi and antennae pitchy-red. 



Head transversal, coarsely punctured, but with the basal space nearly 

 smooth, considerably depressed on the middle, the lateral lobes nearly 

 dividing the eyes ; mandibles stout, notched at apex, bi-dentate inwardly, 

 coarsely sculptured, but more finely near the extremity. Frothorax
