POOONIUAE. 365 



0. probus (2(jl6), from Westpoit, is tlu' specif s most resembling this, 

 but it is smaller, the thorax is incurved in front, and narrower ; the elytra 

 are more attenuate posteriorly, the brighter testaceous apical marks extend 

 nearly to the hind thighs, their outer striae are obsolete, and there are no 

 punctures on the 3rd interstices. 



Length, 5 J mm. ; breadth, 2| mm. 



Moa and Mistake Basins, near Mount Algidus. A male and two females, 

 discovered by Mr. T. Hall on the 20th October, 1913. 



3807. Oopterus suavis sp. nov. 



Glossy, moderately convex ; rufo-piceous, the lateral margins, base of 

 thorax, elytral suture, labrum, and mandibles piceo-rufous ; femora some- 

 what testaceous; palpi fulvescent ; tibiae and basal joints of antennae more 

 or less light fusco-rufous, remaining articulations of the latter darker ; 

 elytral apices sometimes pallid. 



Head, with its large, moderately convex eyes, rather broader than front 

 of thorax, smooth, with elongate frontal impressions, labrum subtruncate. 

 Thorax subcordate, distinctly margined, a fourth broader than long, widest 

 at the middle, well rounded to beyond that point, gradually and slightly 

 sinuously narrowed behind, posterior angles just rectangular, base and apex 

 subtruncate ; disc usually almost smooth, having only some very obsolete 

 striae across it, the central groove in some aspects appears to attain both 

 base and apex, basal fossae moderately large and deep, their outer borders 

 carinate, the base irregularly and finely but quite perceptibly punctured. 

 Scutellum triangular. Elytra oval, broadly margined, thrice the length but 

 not double the width of thorax in the middle, slightly broader than it is 

 at the base, with distinctly singly rounded apices, which are sometimes 

 testaceous ; the sutural stria on each is rather deep and finely punctate, 

 the 2nd less so, the others are indistinct ; interstices nearly flat, the 3rd 

 tripunctate ; the suture is bent outwardly at the extremity and prolonged 

 forwards as a carina nearly in line with the 5th interstice. 



Underside like the dorsum in colour, but with rufescent coxae and tro- 

 chanters. Last segment of abdomen in the male, at the apex, with a single 

 setigerous puncture at each side of the middle ; in the female bipunctate 

 there. 



0. latifossxis may be easily separated by its less convex body, by its 

 thorax being broader in front, more sinuate behind, with sharper hind 

 angles, broader fossae, and more coarsely punctured base, and materially 

 difi.'rent elytral sculpture. None of the subantarctic islands species closely 

 resembles ours. 



S- Length, 5-5| mm. ; breadth, nearly 2\ mm. 



Routeburn and HoUyford. Several specimens secured at night off moss- 

 covered trees by Mr. T. Hall during February, 1914. 



3808. Zolus ocularius sp. nov. Zolus Sharp, Man. N.Z. Coleopt., p. 1000. 



Nitid, elongate-oval, of somewhat interrupted contour, slightly convex ; 

 piceous, the lateral margins, elytral suture, and sometimes the head and 

 base of thorax piceo-rufous ; legs and antennae usually rufo-castaneous, 

 basal joints of these latter and the palpi fulvescent. 



Hrad oviform, almost as long as thorax but obviously narrower, with 

 nearly flat eyes. Thorax nearly a fourth broader than long, widest near 

 the middle, curvedly narrowed anteriorly, gently but not curvedly narrowed
