410 Transactions. 



Male. — Abdomen elongate, 1st segment ciliate behind, only slightly 

 exposed, 4th rather shorter than 2nd or 3rd, 5th widely incurved at the 

 apex, the 6th more deeply, 7th small. 



Female. — 5th segment nearly truncate at the extremity, 6th not abbre- 

 viated. 



This small species may be identified by the antennal structure and 

 zealandius-like elytral striae.

Erua and Raurimu, January, 1910. Three or four specimens were 

 also found amongst leaf-mould collected at Makatote by Mr. W. J. Guin- 

 ness, and at Retaruke by Captain H. S. Whitehorn, in March. 



3208. Euplectopsis biimpressus sp. nov. 



Elongate, nitid ; pubescence yellowish, nearly suberect on the elytra; 

 rufous, legs and antennae paler, tarsi and palpi Havescent. 



Head smaller than thorax, straight behind the prominent eyes, punc- 

 tate and slightly asperate, the foveae somewhat prolonged anteriorly, 

 antennal tubercles rather small and distant. Thorax oviform, slightly 

 longer than broad, the middle widest, more gradually narrowed towards 

 the front than behind ; it is less distinctly punctate than the head, the 

 discoidal groove is distinct and extends into but not beyond the basal 

 fossa, which is connected with the large lateral foveae. Elytra rather 

 longer than thorax, curvedly narrowed towards the base, indistinctly 

 punctate; the sutural and interhumeral striae broad and deep at the 

 base, separated by slightly raised lines. Hind-body rather longer than 

 elytra; 3rd segment quite as long as the 2nd, and only slightly deflexed; 

 basal segment with a deep transverse impression in front, the 2nd 

 similarly but less deeply impressed, both of these impressions without 

 cariniform margins. Antennae stout, their 2nd joint slightly thicker 

 than the 1st, quite as long as it is broad; 3rd slightly larger than the 

 shorter 4th, neither quite as broad as the 2nd ; 5th distinctly broader 

 than adjoining ones; 6th and 7th transverse, broader than the shorter 

 8th; 9th and 10th transverse, the latter evidently larger than the 9th, 

 and as broad as the large, conical, terminal joint. 



The lather narrower outline, enlarged 5th antennal joint, and the 

 additional impression on the 2nd dorsal segment will aid in its separa- 

 tion from E . heterarthrus.

Raurimu. I obtained my specimen in January, 1910, at the bottom 

 of a steep ravine. 



3209. Pycnoplectus cephalotes Reitter. Euplecfus. Verh. d. naturf. ver. 



Brunn.. vol. 18. 



Rufescent, shining, very finely pubescent. 



Head large, transversely quadrate, as broad as thorax, frontal foveae 

 subparallel, united in front, apex deeply foveolate. Thorax with the 

 discoidal sulcus much abbreviated in front. Elytra with the sutural 

 striae entire, the dorsal very short and broad, and with 2 punctiform 

 foveae at the base. Basal three dorsal segments almost equal, the 1st simple. 



Very like Euplectus erichsoni. The head larger and more quadrate, 

 with shorter frontal furrows opening out into larger grooves behind. 

 Thorax wider, the median groove sharply impressed. 



Length, 2 mm.
