OF NEW ZEALAND. 825. 



between them plane or nearly so, the third and seventh with large 

 punctures, the marginal sculpture not differing materially from that 

 of pretiously-described species. Underside glossy black. 



This species, owing to its short broad thorax and finely-grooved 

 wing-cases, with flatfish interstices, presents a striking contrast to 

 nearly all the described TricJiosternii.

This individual was captured on Maungatua by Mr. S. W. 

 Fulton. 



1466. T. CSphaloteS, ^'-s. Yiridescent, shining ; legs piceous ; 

 tarsi, antennae, and palpi piceo-rufous ; black below. 



Head uncommonly large, including the eyes almost as broad as 

 the thorax but decidedly longer than it, with two frontal fovese, but 

 otherwise perfectly smooth, and of a glossy green. Prothorax quad- 

 rate, convex, apex arcuated, base slightly so, its sides not greatly 

 curved except at the anterior angles, gradually narrowed and just 

 perceptibly sinuated behind ; posterior angles quite rectangular, not 

 projecting ; with a distinct dorsal groove terminating in the shallow 

 curved frontal impression ; basal fossae large, with an intervening 

 depression, and having a few aciculate marks on the middle. 

 Scutellum black, scored with sbort grooves. Elytra convex, sub- 

 oblong, widest behind, narrowed anteriorly, moderately rounded 

 laterally, sinuously narrowed apically, humeral angles not very 

 protuberant ; the discoidal furrows, except the sutural, rather deep 

 and finely punctured, interstices convex, the third and seventh with 

 three or more large punctures, eighth smooth, bordered by the usual 

 row of catenulate punctures, having an outer, somewhat interrupted 

 stria, and a line of elongate impressions close to the rim, which 

 becomes obsolete behind. Legs normal. 



The large head, in conjunction with the almost uniform bronzed- 

 green colour of the surface, seems to differentiate this species from all 

 but T. capito, which should have large punctures between the fotirtli 

 and fifth striae. 



? . Length, lo^ lines ; breadth, quite 3f . 



A single female is all I have seen. It was taken on the range 

 near Wellington by Mr. P. Stewart-Sandager. 



1467. T. vagans, n.s. Narrow, slightly convex, glossy black; 

 legs and antennas piceo-rufous, underside black. 



Read rather small, not very broad, with shallow frontal fovea? , 

 otherwise smooth ; eyes prominent. Prothorax convex, apex in- 

 curved and ciliated, transversal, strongly rounded laterally and con- 

 siderably sinuated behind, posterior angles rectangular (though 

 appearing more prominent than they really are), base medially 

 arcuated ; basal fossae moderate, united by a shallow^ impression, 

 discoidal groove narrow but somewhat expanded behind, the surface 

 with many very fine undulating striae. Scutellum striate at base. 

 Elytra oblong-oval, regularly rounded laterally, obviously sinuously 

 narrowed apically, humeral angles dentiform; each with a short 

 scutellar and eight punctated striae, the two sutural rather fine,
