OF NEW ZEALAND. 915 



small but distinct ; interstices slightly convex, the third tri-punctate, 

 seventh multi-punctate. Legs robust. Underside pitchy-black, with 

 fine linear marks. 



The conspicuous thoracic angles distinguish this species.

Invercargill. Discovered by Mr. T. Chalmer. 



1637. T. COnvexuS, n.s. Oblong, convex, shining, cupreo- 

 niger, legs and antennae rufo-piceous. 



Head nearly smooth ; eyes prominent, orbits inflated. Prothorax 

 quadrate, transversal, apex incurved, base widely emarginated, sides 

 moderately rounded, with a short sinuosity behind, causing the 

 angles to appear prominent ; disc rather convex, the basal portion 

 between the fossae somewhat flattened, with a curved frontal im- 

 pression, dorsal stria distinct. Scutellum striate. Elytra oblong, 

 but little rounded, shoulders dentate, apical sinuations distinct; 

 sub -punctate -striate, striae deep ; interstices moderately convex, the 

 third with three, the seventh with several large punctures, feebly 

 impressed transversely. Underside pitchy-black. 



The thorax is more convex than in any species as yet described 

 from Otago. T. angulalus makes the nearest approach to it in that 

 respect, but the angles differ. The punctures in the elytral furrows 

 are hardly discernible.

Another of Mr. Chalmer's captures near Invercargill. 



1638. T. agriotis, n.s. Elongate-oblong, convex, shining-black, 

 tarsi and antennae piceous, apices of palpi rufescent. 



Head nearly smooth, not broad ; eyes conspicuous, their orbits 

 inflated. Prothorax quadrate, yet rather broader than long, mode- 

 rately convex, its sides moderately rounded from the anterior angles 

 to near the base, from thence sinuously narrowed to the rectangular, 

 hardly protuberant, angles, apex incurved, base emarginated ; basal 

 fossae large, leaving only a small raised space between them and the 

 sides, median furrow abbreviated in front, slightly curvedly impressed 

 near the apex. Scutellum striate at base. Elytra convex, shoulders 

 dentate, apical sinuosities moderate; punctate-striate, the puncta- 

 tion fine ; interstices convex, the third with two or three, the fifth 

 with one (perhaps none in some examples), the seventh w r ith several 

 large punctures, these impressed interstices rather broader than the 

 others. Legs stout. Underside black. 



Allied to the preceding species (T. meritus), yet 'abundantly 

 distinct ; the hind-body is more convex, and the plain black colour 

 is relieved by faint tinges only of a coppery colour on the depressed 

 parts of the thorax.

 species also.
