instead of being simply curvate, are obtusely angulate externally. The 
series of coarse punctures across the front of the thorax in C. tibialis is 
another peculiar feature.

Mount Dick. Unique. Another of Mr. T. Hall’s captures on or about 
the 13th March, 1914. 
3968. Caccomolpus viridescens sp. nov. 
Convex, broadly oval, glabrous, nitid; greenish-black, head of a more 
brassy hue ; labrum, palpi, and legs fusco-rufous, antennae fulvescent. 
Head smooth near the eyes, finely punctate-rugose elsewhere. Thorax 
more than twice as broad as long, apex widely incurved and finely margined, 
the sides gradually narrowed, but not distinctly rounded towards the front, 
posterior angles rectangular ; disc finely and irregularly punctured, the sides 
nearly smooth. Scutellum short. Elytra of the same width as thorax 
at the base, more than thrice its length, broadly rounded behind, their 
margins most distinct near the shoulders; each with 3 or 4 inner series 
of moderately fine punctures which scarcely reach the extremity, the 
external series less distinct and more irregular, the intervals minutely and 
rather distantly punctate. Pygidium slightly exposed, rufescent. 
Tibiae with distinct yellowish pubescence below the middle; the 
anterior straight inwardly, slightly dilated and curved outwardly, the others 
slender near the base, dilated and obtusely angulate, the intermediate 
especially, outside below the middle. ‘Tarsi simple. 
Antennae longer than head and thorax, finely pubescent towards the 
extremity ; basal joint stout, curved on the inside, 2nd nearly thrice as 
long as broad, joints 3-5 about equally slender and elongate, 6—LO longer 
than broad, narrowed towards the base, the terminal elongate-oval. 
Underside finely and irregularly punctured, with very fine inconspicuous 
setae ; metasternum flat, rather longer than the basal segment, which is 
truncate in front and nearly equals in length the following 5 together. 
This, owing to the tibial structure, should be placed near C. jflectipes 
(3667), which, however, is of a faintly reddish-bronze hue, with a larger 
scutellum, &c. C. tibialis has shorter antennae and coarser sculpture. 
The specimen described above, judging by its tarsi, is apparently a 
female.

3969. Allastena eminens sp. nov. Allastena Broun, Man. N.Z. Coleopt., 
p. 1318. 
Oblong, subdepressed, nitid; nigro-aeneous, the tibiae and basal 4 
joints of antennae fusco-testaceous ; remaining joints, the tarsi, and femora 
more infuscate ; sparingly clothed with elongate, slender, suberect, tawny 
pubescence. 
Head nearly as broad as front of thorax, smooth behind, with a few 
fine interocular punctures and a distinct channel between the antennal 
orbits. Thorax a third broader than long, apex truncate ; the base nearly 
so, marginate and a little rounded near the sides so that its angles are some-
