to record here an error in the description of //. insignis (Proc. 

 Linn. Soc, N.S.W., 1888, p. 1332), by which its antennae 

 were said to be 8-jointed, and that (with its other characters) 

 * would place it in this group. Its antennae have 9 joints, and 

 I can account for the mistake only by supposing that after 

 I had examined the antennae I intended to place it among 

 those with 9-jointed antennae awaiting description, but by 

 some oversight placed it among those with only 8 joints in 

 their antennae. It is a member of Group IV. 



The following is a tabular statement of some of the dis- 

 tinctive characters of the Heteroriyce^ of this group: — 

 A. Hind angles of prothorax (viewed from 

 above) quite defined (size moderate, 

 3 1. or more). 

 B. Elytra having an apical row of 



granules bearing stout bristles 

 BB. Apex of elytra not as B. 



C. Ciypeus and frons present a con- 

 tinuous surface. 

 D. Head and pronotum uniformly 

 confluently and asperately punc- 



tulate 



DD. Pronotum smoothly and not 

 closely punctulate 

 CC. Ciypeus on a plane quite differ- 

 ent from that of frons. 

 D. Elytra non-striate and upper- 

 most tooth on front tibiae obso- 

 lete 



DD. Species not combining the two 

 characters of D. 

 E. Apical part of elytra deplan- 

 ate in front of its mem- 

 branous border. 

 F. Front face of labrum dis- 

 tinctly wider than its dis- 

 tance from summit of 



ciypeus 



FF. Front face of labrum dis- 

 tinctly narrower than its 

 distance from summit of 



ciypeus 



EE. Elytra not deplanate in its 

 apical part. 

 F. Elytra distinctly substriate. 

 G. Elytral puncturation rugu- 



lose 



GG. Elytral puncturation 



smooth 



FF. Elytra non-striate (the 

 subsutural stria of course 



excepted) 



AA. Hind angles of prothorax entirely 

 rounded off (size very small, less than 

 2 1)
