408 COLEOPTERA. 
Difierentiated from P. binodes (776) (Empaeotes crispatus Pascoe) by the 
absence of rugosely tubercular thoracic sculpture, and from P. brevicornis: 
by the less rotundate eyes and anteriorly prominent 3rd elytral inter- 
stices, &c. P. humeralis (3119) may be at once separated by the broadly 
margined frontal portion of the sides of the hind-body, and the pair of 
outstanding sutural prominences below the top of the posterior declivity. 
Length (rostrum inclusive), 1] mm. ; breadth, 44 mm. 
Mount Moa, Canterbury. One, taken off a tree at night by Mr. T. Hall,. 
20th October, 1913. 
3875. Platyomida cuprealis sp. nov. 
Subopaque, the derm somewhat glossy black: covered with small, 
depressed, coppery squamae, and bearing also some more elongate setiform 
ones on the elevated parts; funiculus red, tarsi piceous. 
Rostrum a little expanded anteriorly, slightly shorter than thorax; the 
central carina distinct, with an elongate impression along each side of its 
basal half. Thorax of the same length and breadth, only very shghtly 
wider before the middle than behind, gently narrowed anteriorly; the 
surface only slightly asperate but without discernible punctures or rugae, 
the discal channel interrupted, broader and deeper in front than behind. 
The sunken scutellum small. Elytra oblong, gradually narrowed towards 
the base, which is a third broader than that of the thorax, just thrice its 
length, their sides scarcely at all uneven, much narrowed and _ vertical 
behind ; only a single series of small interrupted punctures can be seen 
along each side of the suture, the single ones between the common 3rd 
and 5th interstices are very coarse, rather shallow and irregular, the double 
series near the sides are also irregular but only moderately coarse; 3rd 
interstices slightly porrect but distinctly elevated at the base, with a pair 
of elongate elevations along the middle, the terminal nodosities are mode- 
rately large and horizontal but hardly extend beyond the top of the 
declivity: 5th flat near the base, but extending obliquely backwards as 
almost continuous ridges, their terminations not quite as prominent as 
those of the 3rd, and not projecting outwardly as in P. dorsalis; the 
declivity has a pair of distinct nodosities near the top and some small 
tufts lower down. 
Antennae finely setose ; scape gradually and slightly incrassate towards 
the extremity ; joints 3-7 of the funicle obconical, all longer than broad ; 
club elongate-oval, dull, finely pubescent. Tibiae normal, sparsely denti- 
culate inwardly. 
Underside nigrescent, the greater portion thickly covered with bright 
fulyous scales and paler setae, the last 3 ventral segments bear setae only, 
5th closely punctured and emarginate at the apex. Head distinctly trans- 
versely rugose. 
The elytral sculpture is manifestly different from that of any recorded 
species. When quite fresh the scales no doubt are of a reddish-coppery 
hue. The 5th elytral interstices, and the row of coarse punctures between 
each of them and the 3rd, are, I think, quite a ager characters. 
Length (rostrum inclusive), 10} mm.; breadth, 44 mm. 
Mistake Basin, Canterbury. One example, minus an antenna, found 
by Mr. T. Hall on the 9th October, 1913, amongst dead leaves on the 
ground.
