470 COLEOPTERA 



times concentrated as patches. The under-side is punctate, and densely 

 clothed with whitish pubescence, and the metasternum is longitudinally 

 furrowed. 



Length, 3 lines (rost. inch). 



The five examples of this fine species, which I found at Whangarei 

 Heads, exhibit scarcely any variations of size or colour. 



832. P. sumptuosa, n.s. Body brilliant green with a reddish 

 hue, the latter prevailing along the sides ; antennae, tibiae, and tarsi dull 

 red, femora greenish. 



Rostrum elongate, almost twice the length of the head, smooth and 

 shining, its apical half red ; the point of insertion of the antennae very 

 near its base, and protuberant, giving the basal portion a somewhat 

 constricted appearance. Head very coarsely and closely punctured. 

 Thorax so sculptured as to appear covered with transversal rugosities, 

 interrupted by a not very distinctly impressed dorsal line. Elytra 

 cylindrical, being, with the exception of the slightly dilated humeral 

 angles, very narrow and parallel-sided, covered with transversal rugosities 

 and punctate intervals ; with a sutural depression near the base, and 

 bearing, on each, a patch of white hairs on the middle and another at 

 the apex. 



Legs stout, with slightly flexuose tibiae, and somewhat expanded 

 tarsi. 



Length (rost. inch), 4 lines ; breadth, nearly i. 



I am indebted to Mr. Robert Peace, of Parua, for the only specimen 

 I have seen. 



Agathinus. 



Nov. gen. 



Head oblong, transversely convex ; rostrum not so wide as (but 

 about twice the length of) the head, robust, slightly arched, cylindrical, 

 curvedly narrowed before and behind the middle ; scrobes small, puncti- 

 form. Antenna, straight, longer than head and thorax, gradually dilated; 

 basal joint about as long as sixth, obconical ; second shortest, as stout 

 as first ; third slender, elongate, not so long as fourth and fifth con- 

 jointly ; fourth and fifth slender, the former the longer ; sixth and eighth 

 nearly equal ; eighth and tenth rather shorter than the preceding ; 

 eleventh joint oblong-oval, pointed, longer than tenth. Eyes moderate, 

 very prominent, rounded, not at all coarsely facetted. Prothorax sub- 

 conical, about as long as broad, uneven, apex truncate, the base emar- 

 ginated at each side of the middle so as to appear trilobed. Scutellum 

 sub-triangular, rather large. Elytra oblong, nearly twice the width (at 

 the base), and four times the length of the thorax, adapted at their base 

 to the prothorax, with almost prominent but rounded shoulders, they 

 are gradually widened, and then narrowed posteriorly, the apices cur- 

 vedly excised, the suture and outer angle produced, the outer tooth 

 more acuminate and prolonged than that of the suture; they are uneven, 

 each terminates outwardly in an obtuse tubercle, and bears two discoidal
