smooth ocular orbits large and gradually narrowed behind. 
Prothorax sub-quadrate, widely incurved apically, base emarginate; 
sides rounded and sinuously narrowed towards the rectangular © 
posterior angles; the dorsal groove extends from the base and 
terminates in the frontal impression ; the basal foveze are deep, 
almost sulciform, but extend outwardly close to the base so as 
to form a transversal depression near each angle. Elytva oblong, -— 
punctulate-striate, interstices somewhat convex ; shoulders den- 
tate. This species is abundantly distinct. On examination it 
will be observed that the basal joint of the antennee is depressed 
or broadly grooved above; that the posterior tibiz terminate 
inwardly in a robust calcar-like process, and that the basal arti- 
culation of the tarsi (hind) is very mnch marae laterally, 
and widely furrowed underneath. 
Male; length, 11 lines ; breath, 4. 
The discovery of this ‘species at Mount Arthur is due to 
Messrs. T. F. Cheeseman and Fred. Combes, of Auckland. No 
females were obtained. 
1331.7 vichosternus combesi,n.sp.—Oblong, sub-depressed ; shinide 
black with green and red metallic reflections, the latter hue pre- 
dominating, antennee and trophi dark red, femora blackish, tibiee 
and tarsi rather clear bright red. Head rather broad, somewhat 
uneven, epistome and vertex bi-punctate; eyes prominent. 
Prothovax sub-quadrate, transversal, rounded laterally and sinu- 
ously narrowed towards the posterior angles; the basal foveze 
are deep and rather narrow, and in addition asmaller depression 
occurs near each angle. Elytva oblong, their humeral angles dis- 
tinct, punctulate striate, interstices plane. 
The following are distinguishing characteristics. The first 
antennal joint is broadly sulcate above, and several of those 
which follow are peculiarly compressed at the sides; the basal 
joint of the posterior tarsus is long and narrow; and the elytral 
interstices, second, fourth, and sixth, are more or less reduced in 
width, particularly in the vicinity of the base. 
Female ; length, 11 ; breadth, 4 lines. 
I have named this fine insect in honour of Mr. Fred. H. 
Combes, of Auckland. It was found by him on Mount Arthur; 
but unfortunately no examples of the male were procured. 
1332. Tvichosternus humeralis,n.sp.—Oblong, moderately convex, 
brilliant greenish black, legs and antenne rufo-piceus, tarsi red. 
Flead not-much narrower than thorax, smooth and somewhat 
contracted behind, forehead with the common impressions ; eyes 
prominent. Pyvothovax transversal, slightly but widely incurved in 
front, base obsoletely sinuated, sides distinctly marginated and 
obtusely rounded, moderately narrowed behind, posterior angles 
rectangular, not protuberant; basal fovesee large and deep, 
united by an impression extending from side to side, the dorsal 
groove attains the base and apex, the curved frontal impression — 
is well marked; its whole surface is evidently striated across, 
has two rounded impressions near the middle, and many 
abbreviated aciculate marks at the base and apex. Scutellum —
