Group POGONIDAE. 
3805. Oopterus minor sp. nov. Odptéerus Guérin, Man. N.Z. Coleopt., _ 
p. 54. 
Glossy, moderately convex, of irregular contour ; .elytra piceous, with 
pitchy-red margins; head and thorax rufo-piceous, legs and basal joints 
of antennae light rufo-castaneous, palpi paler. 
Head, and the large moderately convex eyes, a little wider than front 
of thorax, smooth, with shallow frontal impressions. Thorax subcordate, | 
finely margined, widest and rounded at or just before the middle, gradually 
narrowed towards the rectangular, shghtly prominent hind angles, base 
and apex subtruncate, it is about a fourth broader than long; disc smooth, 
the well-marked central groove not reaching the apex, basal fossae of 
moderate size, situated near the angles, with about 4 punctures between 
them, the lateral plicae obsolete ; the seta at each side, in front of the 
middle, and the other at the hind angle sometimes missing. Elytra broadly 
oval, in the middle double the width and thrice the length of the thorax, 
yet hardly any broader than it is at the base, with well-developed margins 
and subapical plicae ; the sutural stria on each usually well marked and 
punctate, the others more or less obsolete ; imterstices plane, the 3rd 
tripunctate. 
Male—Anterior tarsi with the basal 2 joints dilated, and prolonged 
at inner extremity. Antennae reaching backwards to intermediate femora. 
O. pygmeatus (2618) has oblong-oval elytra. O. parvulus (2617) is 
rather smaller, and the sides and apices of the elytra are broadly testaceous. 
In O. basalis (3684) the elytra are more oblong, with much more definite 
sculpture, and the whole base of the thorax is punctate. These are the 
only near allies. 
$. Length, 34 mm. ; breadth, 1} mm. 
Mount Dick, near Kingston. A single pair from Mr. T. Hall on the 
LOth March, 1914. 
3806. Oopterus latifossus sp. nov. 
Nitid, slightly convex ; piceous, elytral margins pitchy-red, their apices 
fusco-testaceous ; legs and antennae light chestnut-red, the glabrous joimts 
of the latter and the palpi fulvescent ; labrum and mandibles dark rufous. 
Head rather narrower than thoracic apex, smooth, with elongate inter- 
ocular impressions; eyes large but not very convex. Thorax cordiform, 
a third broader than long, widest just before the middle, well rounded 
there, somewhat sinuously narrowed towards the subacute and _ slightly 
prominent posterior angles, distinctly marginate, base truncate, apex nearly 
so; disc smooth, central groove abbreviated but distinct, basal fossae large 
and broad, each separated from the side by a plica, the space between 
them with numerous distinct punctures. Elytra broad, oviform, with well- 
developed rims, thrice the length but hardly double the width of the rather 
broad thorax; their striae moderately deep and distinctly punctate, but 
becoming obsolete near the individually rounded apices, the outer striae 
and punctation less obvious ; interstices very slightly convex, 3rd tripune- 
tate, apical carinae distinct. 
Male.— Anterior tarsi with the 2nd joint little more than half the length 
of the Ist, both dilated, and slightly prolonged at the inner extremity- 
Maxillary palpi setigerous. Thorax with a single seta at each side near 
the middle, and another at the hind angle.
