one, whereas in the previously described species the club is simply elongate- 

 oval. 



Length (rostrum inch), 4 J lines ; breadth, 2 lines. 



Tarukenga. My specimen was taken on the high land near Rotorua. 



3124. Lyperobates ardens sp. nov. 



Subopaque, rufo-piceous, legs and antennae fusco-rufous ; densely covered 

 with elongate flavescent squamae, which when touched with benzine resume 

 their natural metallic and somewhat rufescent hue. 



Rostrum, with 2 l)road grooves extending from the back of the eyes to the 

 middle ; it is of normal size. Thorax of about equal length and breadth, 

 widest in line with the lateral protuberances near the front, its sides behind 

 nearly straight yet slightly narrowed ; disc uneven, with a rather sharply 

 defined central ridge and near the middle a less-distinct transverse one, 

 so that there seem to be 4 rather large cavities ; the apex bears some coarse, 

 erect, greyish setae. Elytra rather narrow and elongate, very uneven, with 

 an interrupted oblique ridge on each extending from the post-humeral 

 prominence to the suture ; just in front of this a pair of nodiform elevations 

 almost form another oblique ridge ; at the middle of the base there is an- 

 other nodosity ; the prominences on top of the rounded posterior declivity 

 are large and somewhat elevated at the sides ; there are 2 smaller nodosities 

 between these, which are greyish ; all the other raised parts are more or less 

 infuscate ; some coarse, irregularly distributed punctures are visible. 



This is the most brightly coloured member of the genus. It is differen- 

 tiated by the more definite ridge and deeper impressions on the thorax. 

 The elytra appear rather narrower than usual ; the lateral prominences near 

 the shoulders, the middle, and at the termination of the disc cause a much 

 interrupted outline ; these last, being somewhat elevated, are in marked 

 contrast to the broad horizontal protuberances of the other species. The 

 superficial inequalities are all more strongly developed. The eyes are sub- 

 truncate underneath. The funiculus is finely setose and shining red. 



Length (rostrum inch), 4 lines ; breadth. If lines. 



Himua Range, Auckland. Amongst leaves, on the ground. Unique, as 

 yet. 



3125. Hygrochus cordipennis sp. nov. Gen., Man. N.Z. Coleopt., p. 702. 



Derm subopaque, piceous, legs dull rufo-castaneous, antennae rufescent, 

 the funiculus shining, tarsi pale shining castaneous ; clothed with small 

 depressed scales of a somewhat metallic coppery lustre, those on the sides 

 of the thorax and in front of the scutellum yellowish ; there are also many 

 erect infuscate setae along the sides and apex of the elytra as well as on tlie 

 legs and scape, but on the small posterior nodules they are grey. 



Rostrum, a third shorter than thorax, bi-impressed behind, obtusely 

 carinate along the middle. Scrobes directed obliquely downwards clear of 

 the eyes ; these are very prominent and longitudinally oval. Club ovate, 

 indistinctly quadriarticulate ; joints 3 and 4 of the funiculus slightly longer 

 than broad, 5-7 moniliform. Thorax as long as broad, sUghtly wider before 

 the middle than elsewhere, just a little uneven above, with a slight obtuse 

 median ridge and a frontal impression near each side ; there are no distinct 

 granules or punctures. Scutellum small. Elytra subcordate, with oblique 

 humeral angles ; the base, nevertheless, is rather wider than that of the 

 thorax, but is nearly double its breadth before the middle ; their sides 

 are a little uneven, yet without distinct prominences ; the apex much
