Coleoptera.] SUBANTARCTIC ISLANDS OF NEW ZEALAND. 117 



Antennae with a few yellow setae. Scape elongate, slender, gradually incrassate 

 towards the extremity. Basal joint of funiculus rather longer and stouter than 

 2nd, 3rd longer than broad, 4-6 beadlike, the others broken off. 



Underside slightly nitid, dark reddish-brown, nearly glabrous, there being only 

 a few short slender brassy setae, densely and minutely sculptured, with very 

 few shallow indistinct punctures, head closely and distinctly transversely striate. 

 Epipleurae extremely narrow throughout. Prosternum moderately incurved. 



Kather longer than the typical species, the deflexed apical portion of the rostrum 

 slightly longer, and bearing yellow in place of white hairs ; the elytra more parallel- 

 sided, with deeper striae ; the scrobes deeper and more sharply limited above, and 

 almost extending to the front of the eyes ; the scape is rather longer ; the tibiae 

 a little flexuous and dilated at the extremity. 



Length (rest, incl.), 3^ lines ; breadth, 1 line. 



Carnley Harbour ; under a log. 



Another of Mr. Hudson's discoveries. Described from a damaged specimen set 

 out on cardboard. 



Stilbodiscus, gen. nov. 



Rostrum rather shorter than thorax, stout, slightly arched, subpterygiate near 

 the front, contracted behind, truncate at apex.. Clypeus short, deeply emarginate, 

 appearing to consist of 2 rounded lobes. Mandibles prominent. Scrobes quite open 

 and expanded above, beginning near the apex, deep there, but becoming shallow 

 towards the eyes. Antennae inserted between the middle and apex of the rostrum. 

 Scape very gradually incrassate, attaining the back of the eye. Funiculus 7-articulate, 

 basal joint as long as 2nd and 3rd combined, 2nd longer than 3rd or 4th, joints 5 to 7 

 moniliform. Club oval, triarticulate, stout. Eyes large, transversely oval, widely 

 distant from each other, just free from thorax. Thorax subovate, as long as broad, 

 without ocular lobes. Scutellum obsolete. Elytra more than twice the length of 

 thorax and rather wider at the base. Pygidium slightly exposed. Legs moderately 

 elongate. Fetnora medially clavate. Tibiae flexuous, the anterior rounded exter- 

 nally at the apex and mucronate inwardly. Tarsi setose, 2nd joint transverse, 3rd 

 deeply lobate, the terminal elongate. Claws simple. Prosternum deeply incurved. 

 The coxae prominent and contiguous ; intermediate coxae also prominent, nearly 

 approximated ; the posterior widely separated. Abdomen elongate, its basal seg- 

 ment longer than the metasternum, 2nd as long as 1st at the sides, 3rd and 4th 

 conjointly rather shorter than 2nd but not abbreviate, 5th nearly as long as the 

 preceding 2 taken together, subconical, the supplementary short, with a deep sub- 

 lunate transverse basal impression. 



This genus is distinguished from all its allies by the somewhat shining body, 

 and must be placed between Hycanus and the New Zealand Clypeorhynchus. From 

 the latter it is differentiated by the structure of the rostrum and antennae, by the 

 absence of ocular lobes, &c. It differs from Hycanus in having longer antennae, 

 an unclavate scape, larger and transverse eyes, and elongate lobes to the 3rd tarsal 

 joint ; these lobes, in fact, are about as long and slender as in the corresponding 

 joint of Clypeorhynchus.
