Cokoptera.] SUBANTARCTIC ISLANDS OF NEW ZEALAND. 107 



inconspicuous fine setae only, but the fine yellow setae attached to the tarsi and 

 the extremity of the anterior tibia are quite discernible. Under a strong magnify- 

 ing lens numerous minute grey setae may be seen on the body. 



Underside shining, black, finely and irregularly punctate, the head transversely 

 rugose and punctate, the femora finely punctured. 



Length, 3|-4 lines ; breadth. If lines. 



Carnley Harbour ; under logs of rata-trees. 



The foregoing description has been drawn up from eight specimens received 

 from Mr. Hudson. 



Pseudhelops quadricollis, sp. nov. (Plate V, fig. 8.) 



Oblong-oval, moderately glossy, apparently nude ; head and thorax violacea- 

 niger, elytra viridescent, legs and antennae piceo-rufous. 



Head moderately closely and distinctly punctured, a good deal narrower than 

 front of thorax. Thorax subquadrate, one-fifth broader than long, its sides nearly 

 straight, only slightly narrowed in front, the base just perceptibly broader than 

 the middle, posterior angles obtusely rectangular, the base distinctly bisinuate, 

 apex slightly and widely incurved, the lateral margins thicker in front than behind ; 

 its punctuation rather closer and finer than that of the head. Scutellum small. 

 Elytra gradually narrowed backwards, a good deal near the extremity, where the 

 margins are more visible than along the sides ; their whole surface finely punctured, 

 not at all striate, the serial punctures rather small, not close to each other, and 

 all more or less obsolete in front of the middle ; there are two slight somewhat 

 elongated obtuse prominences on each near the extremity, and the external interstice 

 is swollen but not quite nodiform. 



Underside black, shining ; closely, rugosely, and very distinctly punctured. Pro- 

 sternal process perfectly flat, not in the least grooved along the middle, finely punc- 

 tured. 



This appears smoother than the typical species ; the slight posterior nodosities 

 do not interrupt the oviform outline ; the elytra, instead of being of a brownish- 

 coppery hue, are greenish ; the eyes are less prominent ; and the shape of the 

 thorax is entirely different. The basal joint of the posterior tarsi is evidently shorter 

 than the terminal one. 



Length, 3|^ lines ; breadth, 1^ lines. 



The Snares ; one individual, found under logs of Olearia Ltjallii by Mr. Hudson. 



Pseudhelops posticalis, sp. nov. 



Suhoi-ate, rather elongate, slightly bronzed, nigro-fuscous, head and thorax sub- 

 opaque, elytra more shining, legs pitchy-red, antennae more rufescent. 



Head rather narrower than front of thorax, its punctuation more shallow and 

 distant and rather finer than in the preceding two species. Thorax one-fourth 

 broader than long, subquadrate, gently curved laterally, a little narrower in front 

 than behind, very little wider at the middle than at the base, which is only feebly 

 bisinuate, with obtusely rectangular angles, apex truncate, the lateral margins more 

 developed near the middle than elsewhere ; its surface very finely and not closely 

 punctured. Elytra elongate-oval, widest near the middle, a good deal narrowed 

 and somewhat prolonged at the apices ; their sculpture not well defined, appearing 

 to consist of rather distant very fine punctures, which, however, on some parts seem
