POGONIDAE. 365 
O. probus (2616), from Westport, is the species 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, 54 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 conyex; 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 ; imterstices 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. 
O. latifossus may be easily separated by its less convex body, by its 
thorax bemg broader in front, more sinuate behind, with sharper hind 
angles, broader fossae, and more coarsely punctured base, and materially 
different elytral sculpture. None of the subantarctic islands species closely 
resembles ours. 
$. Length, 5-54 mm.; breadth, nearly 24 mm. 
Routeburn and Hollyford. 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. 
Head 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
