764 COLEOPTERA 



elevations on each side of the median groove, the basal laterally 

 compressed and carina-like, those near the posterior declivity most 

 prominent but romided ; just beyond these (laterally) are two others 

 placed near the middle. Legs finely hispid, outer edge of tibiae with 

 numerous short denticles. 



"When denuded of the greyish sappy or scale-like matter, it will 

 be seen that the head and thorax are irregula-rly granulated; the 

 elytra bear regular rows of granules, there being four such on the 

 discoidal elevation, and seven on each side ; of these latter the six 

 inner form pairs ; these nodules or gramilar elevations are glossy, 

 and in some lights give a punctate appearance to the elytra ; the 

 interstices are brown, but the insect otherwise is almost wholly 

 ferruginous, wdth short yellow setae on the more elevated parts. 



Length, nearly 3 lines ; breadth, 1^. 



I found one example on the "Waitakerei Eange. 



Note. — No. 325, Tarj^hiomimus acuminatus, belongs to this 

 genus. 



1355- D. nndosus, '^-s- Uneven, sub-oblong; piceous, varie- 

 gated with greyish to fuscous ; setae, antennae, and tarsi dark-red. 



Head granulated ; antennal orbits large. Prothorax transversal, 

 considerably contracted behind, its sides nearly flat and divided into 

 five lobes, the anterior largest, posterior angles rectangular ; dorsum 

 considerably raised, with three laterally compressed elevations on 

 each side, the frontal largest and porrected ; it bears numerous 

 granules. Elytra oblong, margins serrate, apices protuberant ; disc 

 elevated, broadest behind, with vertical sides, granulated, with a 

 large basal, median, and ante-apical depressions ; the sides of the disc 

 are irregularly raised, and bend inwards in such a manner as to 

 partly isolate the hollows ; all but the basal are interrupted by the 

 raised suture, so that there appear to be five depressions instead of 

 three ; the margins terminate behind in two obvious protuberances 

 having a large semi-circular intervening gap. Legs clothed with, fine 

 yellowish setae, the tibiae with many denticles on their outer edge. 



The insect is remarkable on account of the whole disc of the 

 elytra being abruptly elevated, the raised edges being nearly on a 

 line with the side margins, and the posterior protuberances extending 

 nearly as far as the apices, whilst the enclosed space seems, at first 

 sight, one large depression. 



Length, 2^2| lines ; breadth, i^-if . 



I have seen two specimens only ; one has been returned to 

 Mr. Sydney W. Fulton, who found both at Outram, Otago. 



Recyntus. 



Nov. gen. 



Body rather short and broad, convex, tuberculate, setose. 



Head sub-trigonal; eyes convex, coarsely facetted; antennal 

 insertion at the sides in front of the eyes, prolonged as a smooth 

 groove along the front and side of each eye. Last joint of maxillary 

 ]jalxn thick, obtuse. Antenna 1 1 -articulate ; basal joint stout,
