3683. Metaglymma curvidens sp. iu»v. Metaglynima Bates, Eiit. Mo. Mao-., 

 1867. p. 78, ;oiid M;in. N.Z. Coleopt., p. 10. 



Elongate, slightly convex, moderately nitid ; black, antennae, palpi, 

 and tarsi rufo-piceous. 



Head rather narrower than thorax, depressed and obsoletely wrinkled 

 behind the prominent eyes, with well-marked irregular rugae, and a seti- 

 gerous puncture, near each of these ; forehead minutely punctate and 

 broadly trisulcate ; labrum almost semicircular, with 6 setigerous punc- 

 tures ; mandibles curvate, distantly punctured. Thorax apparently elon- 

 gate, yet of exactly equal length and breadth, the sides finely margined, 

 indistinctly crenulate, nearly straight to behind the middle, somewhat 

 abruptly contracted and parallel near the base ; disc nearly plane, with 

 fine transverse striae, median groove distinct but not attaining the apex, 

 basal foveae moderate, situated close to the lateral margins. Elytra obloni^- 

 oval, twice as long as thorax, rather broader than it is at the base, a little 

 wider near the hind thighs, gradually narrowed posteriorly ; each elytron 

 with 8 moderate, finely and rather indistinctly punctured striae, these are 

 deeper at the base, but become obliterated by the rugose irregular apical 

 sculpture ; interstices almost plane, the 3rd, 5th, and sutural slightly broader 

 than the others, the 7th unipunctate near the hind thigh, the broad space 

 between the external striae and lateral margin is smooth. 



Antennae extending backwards to the middle of thorax, joints 5-7 

 scantily, the following ones more evidently pubescent, 3rd ratlier longer 

 than contiguous ones. 



Tibiae, anterior and intermediate, prominent at the outer extremity, the 

 posterior less so, the middle and hind pairs somewhat asperate. 



Flanks of prosternum, the mesosternum, and terminal ventral segment 

 finely transversely striate ; this last segment quadripunctate at the apex. 



Mentum tooth triangular, acute and curved upwards at the extremity, 

 with a pair of conspicuous setigerous punctures at its base. Palpi stout, 

 their terminal articulations suboviform, truncate at apex, double the leno-th 

 of the penultimate. 



The elongate form, indefinitely punctate elytral striae, the interfemoral 

 punctures, and the peculiar mentum tooth, conjoint^, distinguish this from 

 every described species. 



?. Length. 20 mm. ; brei'dth, nearly 6 mi:i. 



Opotiki. A single female received during December, 1912, from Mr. 

 F. R. Fiekl. together with some other species of Coleopteio.

 p. 54. 



Nitid, piceous, lateral margins of the thorax and elytra, and the suture 

 of the latter, piceo-rufous, head and thorax sometimes equally rufescent, 

 legs and antennae chestnut-red, palpi infuscate, paler near the extremity. 



Head with well-marked interocular furrows, and, including the larije 

 slightly convex eyes, as broad as the thoracic apex. Antennae stout, attain- 

 ing the shoulders. 1st and 2nd joints glabrous. 3rd and 4th more scantilv 

 pubescent than the following ones. Thorax slightly broader than lona, 

 rounded and widest at or just before the middle, gradually but evidently 

 narrowed behind, wath distinctly rectangular posterior angles ; disc a little 

 convex, almost smooth, median groove well marked but not reaching either 

 base or apex ; basal foveae moderately large, not prolonged forwards, each
