3268. Lyperobates rostralis sp. nov. 



Robust, opaque, piceous, thickly covered with slender depressed pale 

 yellowish-brown scales, and numerous coarser and more flavescent ones ; 

 antennae and tarsi fusco-rufous. 



Rostrum with a pair of broad basal grooves which do not extend 

 forwards as far as the middle, and a fine median carina in front ; the head 

 and rostrum conjointly just the same length as thorax ; the interocular 

 fovea small and quite punctiform. Thorax with 4 large impressions, two 

 frontal and two basal, and with irregular intervening elevations ; there are 

 a few small black granules along the middle, but no punctures are dis- 

 cernible ; it is of equal length and breadth, distinctly more dilated before 

 the middle than it is elsewhere ; the yellowish setae or scales are some- 

 what congregated in front. Scutellum small and short. Elytra not wider 

 than thorax at the base, the shoulders gradually widened to beyond the 

 middle thighs and at that part not quite double the breadth of thorax, but 

 slightly wider than the lateral dilatations on top of the apical declivity ; 

 between these lateral prominences there is a small nodosity ; the disc is 

 not quite level, as from each shoulder an obtuse, more or less interrupted, 

 ridge extends obliquely backwards to beyond the hind thigh, but does not 

 reach the suture ; the 3rd interstices are elevated at the base ; they are 

 indistinctly seriate-punctate, and bear some minute black granules near 

 the suture ; the flavescent squamiform setae are serial near the suture ; 

 the sides and posterior declivity are vertical and seriate-punctate. 



Scape nearly straight, and gradually thickened ; 2nd joint of funiculus 

 slightly longer than 1st, joints 3-7 each longer than broad ; club elongate- 

 oval. 



Underside piceous, covered with an admixture of greyish-yellow de- 

 pressed coarse and fine setae ; it is very finely and indefinitely sculptured ; 

 the basal segment behind and the 2nd in front are medially impressed 

 lengthways, the 5th is subtruncate at the apex. 



No other species closely resembles this. It is larger than all, except 

 L. guinness i, from which it is differentiated by the much less prominent 

 post-humeral angles and more uneven dorsum. The abbreviated rostral 

 grooves and small punctiform interocular fovea will aid in its identification. 



Length (rostrum inclusive), 11| mm. ; breadth, 5 mm. 



Waimarino. Two found by myself in the forest, on the ground, mid- 

 way between that place and Erua in January, 1910. 



3269. Lyperobates punctatus sp. nov. 



Subopaque, pale castaneous, antennae piceo-rufous ; squamosity dense, 

 somewhat tawny, grey, with a slightly reddish tint, on the legs. 



Rostrum with a slight frontal carina, the broad grooves are confluent 

 behind, so that the middle of the head is depressed ; it is rather shorter 

 than the thorax ; the clypeal portion is rufescent and finely punctured ; 

 instead of the usual interocular fovea there is an oval, smooth, blackish 

 spot. Thorax slightly broader than long, widest and obtusely prominent 

 just in front of the middle, distinctly narrowed anteriorly, nearly straight 

 behind ; its surface uneven, with 4 frontal and 2 oblique basal impressions, 

 the intervals irregularly and obtusely elevated, and bearing some small 

 dark granules near the middle. Scutellum short. Elytra nowhere twice 

 the breadth of the widest part of the thorax, very little broader than it is
