86 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [i'nlniplvm. 



Female. — Underside shining coppery-brown, the last 3 ventral segments paler ; 

 the prosternum, .coxae, and trochanters reddish ; the intermediate ventral segments 

 with 2 fine setigerous punctures, the terminal with 4 at the extremity, which is 

 broadly rounded, and, like the preceding two. impressed near each side. It is from 

 the reversed specimen of this sex that the structure of the underside has been studied. 

 9 . Length, 2J lines ; breadth, 1 line. 



The Snares. 



We are indebted to Mr. Hudson for this valuable little beetle. 



OoPTERUS, (xuerin-Menev. 



Palpi elongate ; 2nd joint of the maxillary broad, strongly arched externally, 

 nearly straight inwardly : 3rd about as long as the preceding one, slender near the 

 base, gradually dilated apically, straight outwardly, arcuate inwardly ; the terminal 

 also elongate, thick at the base, tapering towards the acuminate extremity; pen- 

 ultimate joint of the labial stout, the terminal attached at right angles to the apex 

 of its predecessor, elongate, and tapering towards the extremity. Mentum deeply 

 emarginate, with a simjile prominent median tooth, the outer lobes acute ; it bears 

 2 elongate setae at each side. Ligula angulate at the extremity, with a projecting 

 seta there. Antennae filiform, reaching backwards beyond the base of the thorax ; 

 the basal 2 joints and basal half of the 3rd glabrous, but provided with one or more 

 outstanding setae ; the succeeding ones more or less densely pubescent and setose ; 

 2nd articulation about as long as the exposed part of the 1st. not as stout as it is ; 

 3rd quite as long or longer than the preceding one. 



There are 2 setigerous punctures alongside each eye, 2 on the forehead, 1 at 

 each side of the thorax near the middle, and another at each posterior angle. The 

 sutural margin of the elytra is bent outwards at the extremity and prolonged for- 

 wards near the side as a distinct carina. 



Mrt/e.- -Anterior tibiae notched inwardly, incrassate. but not prolonged at the 

 apex. Tarsi setose, the front with feeble squamae, or spongy, underneath ; basal 

 2 joints moderately dilated and prolonged at inner angles, the 1st oblong or sub- 

 quadrate, the 2nd cordiform ; the 3rd and 4th but little expanded, both subcordate ; 

 intermediate tarsi simple. 



Female. — Basal joint of anterior tarsi stout and (iltjoiig. joints 2 to 4 cordiform 

 and about as broad as the 3rd and 4th of the male. 



The above description has been drawn up from specimens from Carnley Harbour, 

 and substituted for the original one. 



Oopterus clivinoides, Guerin. 



Shining, dark brown. 



Head oblong, narrower than the thorax, smooth, witli 2 broad longitudinal 

 grooves between the antennae. Antennae and palpi yellowish-brown. Thorax 

 convex, cordate, margined, with a feeble median groove, a few fine transverse striae 

 near the sides, with a rather large fossa near each posterior angle, and a few longi- 

 tudinal striae at the basal margin. Scutellum triangular. Elytra much broader 

 than the thorax, especially near the middle, rather convex, quite oval, smooth and
