c?. Length (rostrum inclusive), 6|-8 mm. ; breadth, 2|-3 mm. 



Mount Roberts, Nelson ; 28th December, 1915. A dozen specimens 

 taken by Mr. T. Hall at a height of 4,000 ft., feeding on the flower-buds 

 of the mountain-daisy, 



Zenographus Broun. N.Z. Inst. Bull. 1, Part IV, p. 326. 



4197. Zenographus albinotatus sp. nov. 



Oblong, moderately convex, nitid ; black, partly covered with similarly 

 dark inconspicuous squamae, elytral interstices distinctly marked with 

 numerous irregular patches of small white scales. 



Rostrum quite a third shorter than thorax, stout, arched, moderately 

 dilated and finely punctured in front, the carina along the middle ending 

 at the elongate interocular fovea. Eyes subrotundate, more distant from 

 each other than from the thoracic apex. Thorax only a trifle broader than 

 long, slightly wider and rounded before the middle than elsewhere, gently 

 narrowed towards the subtruncate base ; disc irregularly punctate, more 

 closely on some parts than others, a little uneven, with a few coarse 

 irregular rugae and impressions and a well-marked groove from base to 

 apex, it has only a few white or feebly iridescent scales. Scutellum small. 

 Elytra oblong-oval, quite 2| times the length of thorax, somewhat incurved 

 and rather broader than it is at the base, moderately narrowed and 

 curvedly deflexed behind, with dehiscent apices ; each elytron is tricarinate, 

 the external one is less distinct than the others at the base, all are less 

 evident near the apex, the intervals have large irregular punctiform impres- 

 sions, which, however, become much finer and more regular behind, where 

 there are a few fine setae. 



Underside shining black, finely punctate, with decumbent grey setae, 

 mesosternum with small scales. Basal ventral segment truncate between 

 the widely distant coxae, broadly imj)ressed behind, the second across the 

 middle ; fifth almost as long as preceding two together, nearly straight 

 behind, sixth short and broad. 



Antennae similar to those of Z. metallescens (3756), the club as long 

 as preceding three joints of funiculus, tapering towards the extremity, 

 indistinctly quadriarticulate. 



In Z. metallescens the vestiture is altogether different, the thoracic disc 

 is more uneven, and the elytral punctures are less coarse but almost quite 

 regiilar. In this species the anterior tibiae are mucronate, and the ocular 

 lobes are moderately well developed. 



(^. Length (rostrum inclusive), 9h mm. ; breadth, 3f mm. 



Old Man Range, Otago. One, forwarded by Mr. A. C. O'Connor on the 

 21st August, 1916, but found by Mr. W. G. Howes. 



Hygrochus Broun. Man. N.Z. Coleopt., p. 702. 



4198. Hygrochus monilifer sp. nov. 



Oblong, slightly convex, subopaque ; piceous, antennae chestnut-red ; 

 covered with depressed, slender coppery scales and suberect greyish setae, 

 which latter form six small tufts across the summit of the posterior declivitv. 



Rostrum a fourth shorter than thorax, half its width, parallel ; obtuselv 

 carinate and broadly bisulcate along the middle behind. Thorax verv
