408 COLEOPTERA. 



Differentiated from P. hinodeH (776) {Enipaeotes crispatus Pascoe) by the 

 absence of rugosely tubercular thoracic sculpture, and from P. hrevicornis 

 by the less rotundate eyes and anteriorly prominent 3rd elytral inter- 

 stices, &c. P. humeraUs (3119) may be at once separated by the broadly 

 margined frontal poition of the sides of the hind-body, and the pair of 

 outstanding sutural prominences below the top of the posterior declivity. 



Length (lostrum inclusive), II mm. ; breadth, 4| mm. 



Mount Moa, Canterbury. One, taken off a tree at night bv 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 setifonn 

 ones on the elevated parts ; funiculus red, tarsi piceous. 



Rostrum a little expanded anteriorly, shghtly 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 slightly 

 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 ; ojily 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 ])orrect but distinctly elevated at the base, Avith 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 

 fulvous 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-copper}' 

 hue. The 5th elytral interstices, and the row of coarse punctures between 

 each of them and the 3rd, are, I think, quite exceptional characters. 



(J. Length (rostrum inclusive), 10| mm. ; breadth, 4| mm. 



Mi.stake Basin, Canterbury. One example, minus an antenna, found 

 by Mr. T. Hall on the 9th October, 1913, amongst dead leaves on the 

 ground.
