3563. Pedilophorus aemulator sp. nov. ' Pedilophorus Steffahny = 



Morychus, Man. N.Z. Coleopt., p. 244. 



Convex, oval, glossy; aeneous; head, thorax, and base of elytra nioi'e 

 or less rvit'escent; the legs, mandibles, and basal joint of antennae rufous, 

 remaining joints fusco-fulvous, tarsi testaceous. 



Head distinctly punctured, distantly along the middle, closely near 

 the sides, with many slender grey setae; forehead curved but not 

 margined. Thorax fully twice as broad as long, base bisinuate, with 

 acute angles; the sides straight but narrowed anteriorly, finely 

 margined; apex sinuate near the sides, with acute, dellexed angles; its 

 IJunctation distinct, very irregular, and rather distant, the median 

 longitudinal space almost smooth; it bears a few short, slender, greyish 

 setae. Scutellum smooth, triangular. Elytra almost thrice the length 

 of the thorax, of the same width as it is at the base; their sculpture 

 like that of the thorax, irregular and distant, becoming nearly obsolete 

 behind, the intervals minutely reticulate; some minute setae are dis- 

 cernible. 



Tibiae finely setose, moderately arched externally, the posterior near 

 the base only ; the anterior broadly grooved along the outer part of their 

 front face; tarsal appendages well developed; claws thickened at the 

 base. 



Antennae of about the same length as the head and thorax, finely 

 pubescent ; 2nd joint not quite as long as the basal, and more slender ; 

 joints 3-0 elongate, successively decreasing; 6-10 gradually expanded, 

 the terminal conical, hardly as long as the preceding two combined. 



Underside nitid, fusco-niger, with numerous fine greyish-yellow setae; 

 abdomen finely and closely punctured, the middle of metasternum more 

 coarsely and distantly. Trochanteral portion of coxal laminae nearly 

 twice as long, from front to rear, as the lateral. 



This most nearly resembles P. prohus, 2793, which, however, has 

 blackish legs; it is without setae on the head and thorax; the front 

 tibiae, below the middle, have slightly expanded lateral margins; it 

 has 2 smooth spots on the head, the thorax is less transverse and more 

 closely and evenly punctured, and the tarsi are more slender and elongate. 



Length, 4^ mm. ; breadth, 2^^ mm. 



Curiosity Gully, near Methven. Three specimens were picked out of 

 leaf-mould by Mr. T. Hall on the 9th August, 1912. One of them is 

 without the labrum, so that the mandibles are wholly exposed. 



Group Dascyllidae. 



3564. Mesocyphon bifoveatus sp. nov. Mesocyphon Sharp, Man. N.Z. 



Coleopt., p. 316. 



Elongate, subdepressed, slightly nitid; fuscous, legs and antennae 

 more or less rufo-testaceous, terminal joints of these latter slightly 

 darker, labrum and mandibles rufescent; covered with decumbent, dis- 

 tinct, yellowish-grey, and more slender inconspicuous ashy setae. 



Head almost as broad as the thorax, abruptly narrowed, and pro- 

 longed in front, unimpressed, closely and finely granulate. Labrum 

 and mandibles prominent. Thorax small, a third broader than long, 

 its sides slightly rounded, not at all flattened, finely margined; with 

 subrectangular angles, the anterior somewhat deflexed ; apex truncate, 

 base slightly rounded; the surface rather finely punctate-granulose on 

 some parts, simply granulate on others. Scutellum large, minutely
