specimen above described diifers in having the prothorax less 

 transverse, the teeth of the pectoral canal much shorter and 

 terminating considerably behind the ocular lobes (in the N.Z. 

 specimen they are somewhat curved and terminate level with the 

 lobes); the ocular vibriss£e are shorter, denser and more decidedly 

 golden; the eyes are very distinctly more prominent; the rostrum 

 is narrower with a more regular outline, and the punctures at 

 the base are denser and less clearly defined; from the sides it is 

 seen to be narrow and very gently curved throughout, whilst in 

 the other specimen it is stouter and very decidedly elevated 

 immediatelv in front of the ocular fovea. 



Genus Psepholacipus, n.g. 



Head not concealed; ocular fovea indistinct. Eyes large, sub- 

 reniform, coarsely faceted, not separated the width of rostrum. 

 Rostrum slightly shorter than prothorax, wide, curved, dilated and 

 truncate at apex; mandibles almost concealed. Antenna, moder- 

 ately slender; scape inserted nearer apex than base of rostrum 

 and passing apex; 1st joint of funicle moderately elongate; club 

 ovate, subadnate to funicle. Prothorax transverse, convex, sides 

 rounded, apex much narrower than base but not suddenly lessened, 

 base subtruncate; ocular lobes obtuse. Scutellum oblong-elliptic. 

 Elytra elongate-subcordate, wider than prothorax, shoulders and 

 apex rounded. Pectoral canal wide and moderately deep, 

 terminated between four anterior coxae. Mesosternal receptacle 

 depressed between intermediate coxfe, raised in front, the sides 

 rather narrow ; emargination widely transverse ; cavernous. 

 Metasternum large, the length of 1st abdominal segment; episterna 

 large, truncate posteriorly. Basal segment of abdomen consider- 

 ably larger than 2nd, apex almost truncate, intercoxal process 

 narrow and rather strongly I'ounded, intermediates rather large 

 and flat, their combined length noticeably more than that of 2nd 

 or apical. Legs not very long ; femora comparatively stout, 

 edentate, narrowly grooved, the groove usually concealed, posterior 

 terminated before apex of abdomen; posterior cox£e feebly trans-
