instead of being simply curvate, are obtusely angulate externally. Tlie 

 series of coarse punctures across the front of the thorax in C. tibialis is 

 another pecuhar 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, 6-10 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 follo^ving 3 together. 



This, owing to the tibial structure, should be placed near C. jiectipes 

 (3667), which, however, is of a faintly reddish-bronze hue, with a larger 

 scutellum, &c. G. 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. Colcopt., 

 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-
