78 COLEOPTERA 



punctures, which, however, do not seem to be very constant. Legs 

 moderately long. 



Alesosternal process very narrow and elevated, the metastcruuni 

 elevated at the middle, and terminating between the posterior coxa3 in 

 a rather acute process. Under-side densely clothed with short cinereous 

 pubescence ; the hind legs with long hairs. 



Length, 4-4!- lines ; breadth, 2. 



Described from specimens taken at Tairua and Whangarei Heads. 

 I think the same species occurs throughout New Zealand, as I have 

 another example from Mr. Wakefield. 



144. H. nitidiuSCUlus, n.s. Oblong-oval, moderately convex, 

 greenish-black, with the apex of the elytra and the legs brownish-testa- 

 ceous, and the palpi and antennae yellowish. 



Palpi stout, their terminal joint tipped with black. Head obtusely 

 rounded, slightly convex, and finely punctured ; eyes oviform, their 

 greatest bulk above. Thorax transverse, convex, finely margined, 

 rounded towards the front, finely punctated, its sides brownish. Elytra 

 convex, a little broader than thorax, and about three times its length ; 

 they are rather closely, almost rugulosely punctured, each bears a dis- 

 tinct sutural stria, and their sculpture is rather coarse and confused near 

 the apex. 



There is a more obscurely coloured variety which I am unable to 

 separate from this species. 



Length, \\ line. 



I obtained the specimens now before me at Tairua and Whangarei 

 Heads.

Mention quadrate, slightly rounded in front. Palpi very slender; 

 the labial short, their last joint fusiform, rather longer than the penul- 

 timate ; the maxillary very long, second and third joints large, almost 

 equal, a little arcuated, and slightly thickened apically, the last filiform 

 and shorter. Mandibles bidentate at the end, inner side ciliated. Lab- 

 rum transversal, hollowed, as is also the epistome. Antennce nine- 

 jointed, the basal joint very large, depressed ; the second very much 

 shorter, obconical ; joints three to five very small ; sixth cup-shaped, 

 forming with joints seven to nine an elongate club, which is rather 

 compact. Sciitellum rather large. Elytra oblong-oval, widely rounded 

 behind. Legs slender ; posterior tarsi slightly compressed and ciliated. 

 Mesosternal process narrow. Body oblong-oval, rather or only moder- 

 ately convex. 



145. P. tritUS, n.s. Oblong-oval, moderately convex, a little 

 shining, pitchy-brown, with the thoracic and elytral margins testaceous, 

 legs and palpi reddish-testaceous, the antennal club obscure. Antenmc 

 not much longer than the second joint of the maxillary palpi,
