Abdomen with five segments, the bnsal four nearly equal, 

 fifth very sliort, searcoly \isil)le towards the sides. 



This gentis is closely fdlied to Odontria, and should pre- 

 cede it in the TSew Zealand list. The typical species of 

 both genera, however, differ in shape and general appear- 

 ance, and may he distinguished ahnost at a glance. In 

 Odouirin the metasternnm is moderately ehiugate, and the 

 middle femora are, in lepose, received in a !)road groove or 

 imjires^ion, which is limiied l)y fine frontal and posterior 

 maigins. In Prodoutrm the metasternnm is more reduced, 

 so iliat the space between the middle and bind pairs of h'gs 

 is less than tliat between the front and intermediate ones, 

 just the revcise of \\hat obtains in the older genus, and, 

 moreover, the middle thighs have no depressions for their 

 accommodation, there being a fine elevated carina on that 

 part of the sternum, and behind it the face seems nearly 

 vertical. 



Prodontria Leivisii, sp. n. 



Robust, subovate, a little nitid, almost nude above, there 

 being only a grey fringe under the base of thorax and a few 

 erect scattered setse on the elypeus that can be easily seen; 

 colour fusco-testaeeous, the legs and antennre testaceous. 



Head quite half the width of thorax, its central portion 

 di>tinctly and irregularly punctured, the elypeus coarsely 

 and rugosely punctured, the intervals minutely. Thorax 

 twice as broad as it is long, deeply and widely incurved in 

 front, anterior angles acute and attaining the middle of the 

 eyes ; its sides strongly and irregularly rounded, but in one 

 specimen there is an obsolete angulation at each side, and 

 in it the sides appear to be gradually narrowed towards the 

 base and apex ; base strongly bisinuate, its ai.gles distinct 

 bat not at all projecting; the surface with distinct but finer 

 jjunctures than the head. Sctdellum punctate. Elytra 

 rounccd laterally, not Mider than thorax at the base, apices 

 truncate ; each elytron has eight more or less evident striae, 

 these are moderately finely and regularly punctured, but the 

 apical sculpture becomes confused and puuctiform, and the 

 outer stiice are somewhat abbreviated ; interstices finely and 

 irregularly punctured, in some of these punctures minute 

 setui may be detected. 



Lndtrside testaceous, more or less finely punctured, spar- 

 ingly and finely pubescent, but bearing eloni:ate silky greyish 

 hairs on the prosternura. Club of antennae composed of four
