Group Pycnomeridae. 



3226. Pycnomerus reversus sp. nov. Pycnomerus Erichson, Man. N.Z. 



Coleopt., p. 208. 



Glabrous, slightly nitid, nigrescent, legs and antennae rufous. 



Head subquadrate, evidently narrower than thorax, moderately finely 

 and rather distantly punctate, very deeply bi-impressed throughout. 

 Thorax longer than broad, its sides nearly straight, just perceptibly or 

 hardly at all narrowed anteriorly; the apex with a slight median emargin- 

 ation, its angles not prominent; base somewhat curved, so that the 

 angles are not sharply rectangular ; it is distinctly but not coarsely and 

 rather distantly punctured, moderately bi-impressed along the middle, 

 and with the interval between the impressions rather broad and nearly 

 smooth. Scutellum obsolete. Elytra double the length of the thorax, 

 somewhat oviform, widest near the middle; the base slightly incurved, 

 with incrassate angles, which therefore appear to project slightly out- 

 wardly as well as frontally ; the dorsal sculpture on each elytron con- 

 sists of 4 series of unequal, mostly elongate, punctiform impressions; 

 these are connected by feeble striae, but towards the apex the stria are 

 deep, the sutural particularly so, and also rather broad, so that the 

 adjoining interstice appears costiform ; the suture is broad and slightly 

 expanded outwardly at the base, the 2nd and 4th interstices do not 

 reach the base ; the sculpture near the sides is finer and more punctate- 

 striate; all the interstices and the suture have distant, minute, serial 

 punctures. 



Underside nitid, the sternum coarsely, the abdomen more finely and 

 remotely punctured, its terminal segment with a large fovea at each side. 



Belongs to section I in my cabinet, which comprises species with 

 minute eyes and indistinct 11th antennal joints. Most nearly related to 

 1944, 1949, and 1950, but, independently of other details, differentiated 

 by the finer punctation of the thorax and unusual elytral sculpture. 



Length, 3^-3^ mm. ; breadth, 1-lj mm. 



Greymouth. Three examples from Mr. J. H. Lewis. 



3227. Pycnomerus candidus sp. nov. 



Nitid, castaneo-rufous, antennae rufous, apex of thorax fringed with 

 fine yellowish pubescence. 



Head subquadrate, narrower than thorax, frontal fovae deep ; its 

 punctation distinct but not close. Thorax of about equal length and 

 breadth, very slightly narrowed in front, very gradually so behind, with 

 well-developed lateral margins; apex medially truncate, but with a short 

 sinuosity near each side, thus permitting the small eyes to be easily seen, 

 its angles acutely prominent; posterior angles rectangular, but not ex- 

 tending to the base itself, close to each there is a deep transverse fossa 

 which has a thick hind margin ; it is moderately coarsely and rather 

 distantly punctured; the dorsal impressions are well marked and elon- 

 gate, and are separated by a nearly smooth space which is broader behind 

 than in front, but not cariniform there. Scutellum small. Elytra ovi- 

 form, twice the length of thorax, widest near the hind thighs, a good deal 

 contracted posteriorly; at the base they are singly rounded, yet only 

 gently, towards the suture, the humeral angles project forwards; they are 

 deeply striate, with rather distant and not very definite punctures; the 

 interstices have remote, minute serial punctures; on each elytron the
