Cokoiitera.'} SUBANTARCTIC ISLANDS OF NEW ZEALAND. 89 



Oopterus tarsalis, sp. nov. 



Shining, pitchy-black, lubrum and mandibles rufescent, palpi testaceous, legs 

 also testaceous or slightly infuscate, basal 2 joints of antennae shining ferruginous, 

 the remaining joints dark and opaque. 



Head as long and almost as broad as the thorax, constricted behind the eyes, 

 the frontal imj^ressions like those of 0. marnneri. Thorax apparently narrow, in 

 reality slightly broader than long, its sides almost evenly rounded, yet more but 

 only gradually narrowed backwards than in front, posterior angles rectangular ; 

 dorsal groove very fine, sometimes indistinct near the front ; the basal fossae large, 

 not prolonged anteriorly, the base without distinct punctures or rugae, the disc 

 very vaguely transversely striate. Elytm oval, nearly double the breadth of the 

 thorax, almost obliquely narrowed near the base, the lateral margins and channels 

 well developed ; their striae well marked and finely punctured, but becoming finer 

 towards the sides; the space just in front of the posterior carina almost quite 

 smooth ; 3rd interstices with 3 or 4 punctures. 



Most nearly resembles 0. trifunctatus, from Carnley Harbour, but the thorax 

 seems narrower ; its lateral rims and channels, however, are more distinct. The 

 elytra, though similar in shape, are evidently, instead of being somewhat feebly, 

 striate. The basal 2 joints of the antennae are very percejDtibly differentiated from 

 the following opac^ue ones, and the basal 2 articulations of the male anterior tarsi, 

 though dilated, are much less prominent at the inner angles. This last characteristic 

 and the oval elytra at once distinguish it from 0. mnrrineri.

Campbell Island. 



We are indebted to Mr. Marriner for this species also. 



Oopterus elongellus, sp. nov. 



Body rather elongate, nitid, piceous ; front of head, sides and base of thorax, 

 and the elytral suture and margins more or less piceo-rufous ; the legs and 3 basal 

 joints of antennae chestnut-red, remaining joints darker, palpi fulvescent. 



Head ovate, as long as the thorax but not quite so wide as it is ; labrum, 

 epistome, and mandibles red ; frontal impressions broad ; the groove near each 

 eye also broad, but rather indefinite, owing to the presence of 2 or 3 longitudinal 

 rugae ; the carina somewhat flattened ; ocular orbits dilated, and a little prolonged 

 backwards, so that the back of the head seems somewhat abruptly constricted. 

 Thorax subquadrate, hardly broader than long, slightly wider before the middle 

 than it is elsewhere, moderately rounded towards the front, very gradually and 

 not sinuously narrowed backwards, hind angles rectangular, base truncate, apex 

 very slightly emarginated ; lateral margins distinct, but the channels extremely 

 narrow ; discoidal furrow well marked, but not attaining the front ; the transversal 

 striae feebly impressed ; basal fossae large, but not extended forwards, its base 

 slightly rugose. Elytra rather elongate, oblong-oval, a good deal narrowed pos- 

 teriorly, shoulders rounded, lateral margins and channels moderately developed, 

 not very broad ; their striae well marked and finely punctured except near the apex ; 

 the carinae are present, fine and distinct at the extremity but becoming obsolete 

 within a short distance trom the apices.
