Sp ecies of Ne w-Zealand Coleopiera. 413 



Thorax relatively small, rather broader than long, without 

 distinct lateral margins above, the base widely but feebly 

 bisinuate ; when examined sideways the sides are seen to 

 form a curve from base to apex, the most prominent and 

 deflexed portion being near the middle ; when looked at 

 from above the apex appears nearly half the breadth of the 

 base; there is an oblique constriction or impression at each 

 side in front, and a large well-marked fovea near each side 

 at the base, posterior angles not projecting, the whole surface 

 moderately closely and finely but distinctly punctate. Scu- 

 tellum indistinct, obscured by minute greyish pubescence. 

 Elytra slightly but broadly longitudinally depressed behind, 

 the suture simple but well developed, their surface closely, 

 distinctly, and rugosely punctured. 



Underside nigro- fuscous, with decumbent greyish pubes- 

 cence, rather finely punctured, metasternum most distinctly. 



If the thoracic posterior angles projected backwards this 

 insect might be easily mistaken for a small black Eucnemid 

 or Elater. 



Length 2 ; breadth f line. 



Broken River. 



We are indebted to Mr. J. H. Lewis for bringing this 

 interesting little beetle to light. 



Group (Edemeridae. 

 Selenopalpus rectipes, sp. n. 



Subopaque, cyaneous ; the palpi, antennae, and legs nigro- 

 fuscous; pubescence inconspicuous, cinereous. 



Head immersed up to the eyes, narrowed anteriorly, with 

 a broad groove along the middle of the clypeus ; inter- 

 antennal impressions shallow, vertex slightly longitudinally 

 elevated, finely and closely punctured in front, more distinctly 

 but not so closely behind. Thorax widest before the middle, 

 sinuated behind ; the basal margin, however, not contracted, 

 and a little prominent at the sides ; the surface finely and 

 closely punctate, with a small antescuteliar impression. 

 Scutellum small, medially grooved. Elytra wider than thorax 

 at the base, slightly and very gradually expanded behind, 

 their sculpture rather fine and close, yet ill-defined, not 

 evidently punctiform nor granular, slightly rugose, the suture 

 distinct, the two discoidal lines on each also ill-defined. 



Legs rather slender, tibiae very nearly straight. 



The clavate posterior femora and thick, curvate, apically 

 prolonged tibiae distinguish S. cyanea. In S. aciphyllce the
