OOLKOPTEHA. 



basal elevation, an ohlique one extending' from the side, before the middle, 

 towards the sutnre ; the area between this and the horizontal unj^ular jiro- 

 niinence at the side of the nearly vertical declivity appears dejiressed ; the 

 disc is nearlv truncate beliind, bears several sli^'ht inequalities, and the 

 coarse serial punctures are hidden by the squaniosity ; the sides also are a 

 little uneven. liavin<: a prominence behind the middle : the apex is obliquely 

 narrowed. 



Underside piceous, thickly squamose, the 3rd and 4th ventral segments 

 more sparinglv, but bearing coarse yellow setae. The hrad glabrous, convex 

 behind, but depressed between the eyes. Metastemum short, not foveate. 

 Posterior corhch witlx double ciliae, but only a narrow flattened surface. 



\\'hen compared with L. asper, the type of the genus, this species is seen 

 to have more slender and elongate antennae, the rostral grooves are more 

 shallow, the elytral disc is flatter, with h'ss distinct and numerous nodiform 

 ine(iualitiey. and without conspicuous setae on then) : the sf|uamosity, too. 

 is less hair-like. 



Length (rostrum inch), U lines : l)readth. 2 hnes. 



Waitakerei Range. December, 19U8. I found two amongst leaves on 

 the ground. It is named in honour of Mr. A. Waterworth. of Northcote. 

 who, though not an entomologist, has freely rendered valuable services in 

 the production of micro-photographs for the illustration of my " Revision of 

 the New Zealand Cossoniddf '' and of some other genera of Colcopfcra from 

 the Auckland Islands. 



3123, Lyperobates carinifer .sp. nov. 



Opaque, nigrescent, covered with decumbent fusco-testaceous setiform 

 scales and a few scattered greyish ones, antennae and tarsi fusco-rufous. 



Rostrum and head together rather shorter than thorax ; the ro.strum 

 with a slender shining black carina in front, and 2 broad shallow impres- 

 .sions belijnd. Scwbcs normal, with apical prolongations. TJiorax (juite as 

 long as it is broad, widest and obtusely prominent at the sides before the 

 middle ; uneven above, having 4 frontal and 2 post-median shallow im- 

 pressions separated by slight obtuse elevations. Elytra slightly incurved at 

 the base, and hardly any wider than the thorax there ; shoulders oblicpie. 

 just behind each of these an obtuse prominence extends as far outwards as 

 the horizontal one at the summit of the ])osterior declivity, and between 

 these, at each side, there is a smaller nodosity ; disc slightly flattened, yet 

 on a higher level than the thorax, nearly truncate behind ; at the middle of 

 each, at the base, there is a nodilorm elevation, and 2 others in line with it 

 further back, the central one the smallest ; between these and the side 

 there are 2 more ; the tip of the declivity is giejnsh ; they are apparently 

 seriate-punctate ; the declivity has some coarse punctures, it is not quite 

 vertical, there are 2 or 3 nodosities near each .side of it. and the suture there 

 is obtusely elevated. 



This species is of more elongate outlin*' than L. u.sjiir. with tli«' elytral 

 disc flatter and less asperate. It is'inore like L. ririlitt, which, however, is 

 of a ehocolate luie. with deeper rostral and thoracic impressions, and more 

 outstanding humeral and posterior prominences, so that the sides of the 

 elytra appear more deeply incurved : neither of these species has any dis- 

 tinct carina on the rostrum. The structure of the club in L. carinifi i is 

 perhaps its best distinguishing feature, the 2nd joint being roujided at the 

 Hidc.M and thus distinct Iv marked off from the basal as well as the terminal
