Species of Xeic-Zealand Coleoptera, 391 



there is a pair of less distinct nodosities ; on top of the 

 declivity there are four, the two nearest the suture being the 

 largest; their sides are vertical, but the posterior declivity is 

 not as vertical as in other species, being a little prolonged ; 

 some slighter inequalities may be seen ; the sculpture near 

 the suture is serial, and may be termed either granular or 

 punctiform according to different points of observation. 



Tarsi finely setose. Anterior tibioi seemingly slightly 

 grooved along the front face. AntennoR very sparingly 

 pubescent, second joint ol)Conical and stout, longer than the 

 uncovered portion of the first ; third slender, evidently 

 longer than the succeeding ones ; fourth and fifth longer 

 than broad. 



This species is most like P. indentatus as regards super- 

 ficial inequalities, but the thorax is without indentations, the 

 posterior slope is more gradual, and the insect itself is 

 smaller. It is extremely difficult to determine the exact 

 affinities of these species when one example only is available 

 for examination. 



Length \h ; breadth \ line. 



Otara, Southland, One of Mr. A. Philpott's discoveries. 



Symphysius, gen. nov. 



Antenna' 11-articulated, club abruptly two-jointed. 7am 

 very scantily pilose, almost bare underneath ; the basal three 

 joints slightly longer below than above, the first joint rather 

 longer than second. 



The head behind the mentum is broad and plane, with 

 sharply limited quite straight sides just outside, but inside of 

 the eye there is a cavity, not a groove, wherein the basal 

 joint of the antenna is accommodated. 



In Ulonotus the oblique antennal furrow just passes, without 

 encroaching on, the rounded inner margin of the eye, and 

 passes uninterruptedly to the sculptured part of the head. 

 The tarsi are thickly clothed and the claw^s thickened at the 

 base. 



In Recyntus the antennal groove is straight, but so ex- 

 panded that the inner margin of the eye is shaved off and 

 polished, so as to be quite truncate ; it is limited behind by a 

 distinct oblique ridge, thus separating the smooth deep groove 

 from the sculptured portion of the head, 



Symphysius serratus, sp. n. 



Convex, subobloug ; fuscous, the antennae and legs red ; 

 covered with greyish sappy matter and bearing fine setee.
