The eyes, though large, are much less prominent than in the typical 

 species, and the neck, in consequence, appears less constricted. The 

 labrum is richly metallic and punctured ; the neck is vaguely rugulose- 

 punctured, the rest of the surface of the head is covered with fine 

 longitudinal strigge, less sharp and less continuous than in many other 

 species. The thorax appears, at first sight, rounded, but the refle.xed 

 margin at the dilated anterior part really forms an obtuse angle ; from 

 this the sides are sinuated, and the margin is gradually off to the place 

 where it ceases, a little before the true base. The elytra are long and 

 ample in proportion to the anterior part of the body ; the stride are 

 much less interrupted than usual, and shallow ; they show but slight 

 traces of punctation, and, like the three small discoidal fovese, are 

 tinged with bluish-green. The species has a striking resemblance to 

 Beinbidia, of the section Tachypus. 



Under stones. Otira Pass, South Island (C M. Wakefield). The 

 nigrino variety appears to be rather common. 



One example, from the West Coast, in Mr. Wakefield's collection, 

 has a nearly smooth thoracic surface.

Differs from the allied species in the nearly uniform green colour of 

 its upper surface, including labrum, outer side of the mandibles and 

 femora ; the colour on head and thorax is metallic, on elytra more 

 olivaceous and duller. The usual strigse of the thorax are finer, and 

 more irregular and indistinct than usual, and the two lateral dentiform 

 projections very prominent, the margin between them being biflexuous. 

 The elytra are ample, somewhat depressed and moderately unlevel ; the 

 stride are shallow, and formed of elongate punctures, the usual fovese 

 are broad and shallow. 



Powell. One example, in Mr. Wakefield's collection.
