patches, on the femora there is usually a grey band ; the decumbent setae 

 arc greyish or fawn-coloured. 



Rostrum slightly shorter than thorax, moderately dilated apically, with 

 a slight median carina extending to the middle of the eyes. Thorax cylin- 

 drical, of almost equal length and breadth, very slightly rounded laterally 

 before the middle, base and apex truncate ; a little uneven above, with 

 a slight median ridge, its punctation hidden. Scutellum oblong. Elytra 

 distinctly wider than thorax at the base, the shoulders not narrowed, they 

 are gradually narrowed from the hind thighs to the dehiscent moderately 

 prolonged apices ; rather distantly seriate - punctate ; the .3rd interstices 

 slightly raised at the base, less so on the middle, but terminating on top 

 of the posterior declivity in robust horizontal protuberances, 5th slightly 

 elevated behind. 



Scape moderately stout, bearing greyish setae, and attaining the back of 

 the eye. Funiculus sparsely hispid ; basal 2 joints only moderately elongate 

 and about equal ; 3rd rather shorter ; 4-6 obconical, rather longer than 

 broad ; 7th slightly larger ; club dull, infuscate, densely and finely pubes- 

 cent, elongate-oval, triarticulate. Scrohes deep, quite open above in front, 

 rather short, extending only half-way to the eyes, which are longitudinally 

 oval. Ocular lobes obsolete. Tibiae fiexuous, the anterior inwardly mu- 

 cronate, the others expanded apically and minutely denticulate along the 

 front face ; posterior corbels with double ciliae, and a narrow truncate space 

 outside. 



Underside piceous, with greyish-yellow scales and setae. Prosternum 

 subtruncate in front ; metasternutn not longer than the basal ventral seg- 

 ment, with a foveiform impression behind ; abdomen considerably narrowed 

 posteriorly, finely punctate, 2nd segment shorter than 1st, both slightly 

 flattened. 



Fem. — 4^ by If lines. The sides and apex of the elytra with fewer grey 

 squamae. 



This, owing to the abbreviated scrobes, should be placed near P. amota. 

 It is, however, less uneven and asperate, the nodosities on the 3rd inter- 

 stices behind the posterior femora are absent, those on the summit of the 

 declivity are not at all contiguous and less prolonged backwards, there are 

 no tubercles on the 5th, and the shoulders are moderately prominent.

Mount Quoin, Wellington. Found by Messrs. O'Connor and Simmonds 

 on Asteliae, at an elevation of about 3,900 ft. 



Obs. — P. amota was described on p. 432 of the " New Zealand Journal of 

 Science," 1883, and redescribed by Dr. Sharp as P. coronata in the " Trans- 

 actions of the Eoyal Dubhn Society," 1886. 



3119. Platyomida humeralis sp. nov. 



Robust, piceous, densely covered with fawn-coloured squamae, of a 

 somewhat metallic rufescent hue when alive ; tarsi and antennae fusco- 

 rufous ; the setae paler, quite grey on the legs ; shoulders greyish. 



Rostrum rather broad, subparallel, hardly at all dilated in front, the 

 scrobes, nevertheless, quite open above near the apex, rather deep, and 

 prolonged almost to the lower front of the eyes ; there are 2 broad longi- 

 tudinal impressions above, and a moderate carina between them ; the punc- 

 tation is hidden by the squamae. Thorax of nearly equal length and 

 breadth, slightly wider before the middle than elsewhere, base and apex 

 very slightly emarginate medially ; the disc only slightly uneven, with a
