over, the thoracic setae are absent, though the specimens are quite fresh 

 and uninjured. 



Length, 6 mm. ; breadth, 3 mm. 



Erua, at an elevation of about 2,500 ft. ' Three were found by myself 

 in January, 1910, and two by Mr. W. J. Guinness, railway station- 

 master, in March, all amongst decaying leaves on the ground. Another 

 was found near the base of Mount Ngauruhoe by Mr. Guinness; and 

 one taken previously by myself at Raurimu, elevation 1.900 ft., has more 

 strongly sculptured elytra than the others. 



3172. Tarastethus lewisi sp. uov. 



Glossy, aeneo-niger, elytra! margins and apices, the legs, antennae, 

 and palpi testaceous, mandibles pitchy red. 



Head smooth, reddish in front, interocular impressions elongate, the 

 space between each of these and the lateral groove somewhat elevated. 

 Eyes large, not prominent, finely faceted. Thorax a fourth broader 

 than long, widest near the middle, its sides distinctly margined, mode- 

 rately rounded, slightly sinuously narrowed behind the middle, posterior 

 angles rectangular ; the anterior, though not prominent, are more dis- 

 tinct than usual, owing to the slight dilatation of the lateral margins 

 there; disc moderately convex, smooth, its central sulcus does not attain 

 the apex, the base has duplicate fossae near each side, and the outer one 

 is separated from the lateral margin by a carina. Scutellum distinct, 

 rather broad. Elytra oviform, a fifth longer than broad, widest near 

 the middle, of the same width as thorax at the base, with refiexed mar- 

 gins and rather broad channels; they are moderately punctate-striate, 

 the striae, however, do not reach the base, and, except the sutural pair, 

 become indefinite towards the extremity, and those beyond the 4th are 

 indistinct near the sides; 3rd interstices slightly broader than the con- 

 tiguous ones and rather coarsely tripunctate, the apical carinae are well 

 developed. 



Certain peculiarities are observable in this species. Ihe labrum is 

 remarkable, for in place of being subquadrate, and widely emarginate 

 in front, it is quite conical, and bears an exserted central seta and a 

 pair of finer ones at the sides. The maxillary palpi are finely setose. 

 The inner emargination of the front tibiae is less distinct than usual, so 

 also is the basal margin of the elytra. The surface of the front tarsi is 

 more pubescent. There is only a single ocular seta, and that of the 

 thorax appears to be absent. 



Length, 4| mm. ; breadth, 24 mm. 



Greymouth. Described from a female sent by Mr. J. H. Lewis, whose 

 name has been given to it. 



3173. Tarastethus cordipennis sp. uov. 



Convex, rather elongate, glossy, nigro-piceous, labrum and mandibles 

 dark red; antennae, palpi, and tarsi testaceous, the legs rather darker. 



Head oviform, frontal impressions elongate, and with some fine punc- 

 tures between them. Labrum quadrate. Eyes nearly flat, indistinctly 

 faceted. Thorax apparently elongate, actually of equal length and 

 breadth, lateral margins distinct, slightly thickened behind, it is mode- 

 rately rounded at and before the middle, and distinctly sinuate behind, 

 the base nevertheless is about as wide as the apex, with rectangular 

 angles ; the dorsal furrow does not extend to the apex or base, which 

 latter is very distinctly punctured right across; the basal fossae are
