GQ ON THE SCARITID^ OF NEW HOLLAND, 



Mr. Masters, at the place above mentioned. G. campestre mihi is 

 the species of the group which it most resembles in general form. 



Carenum sdbcyaneum. 



Nigrum nitidum viridi-marginatum sulcis frontalibus sub- 

 parallelis, thorace transverso marginato postice lobato 

 truncate utrinque emarginato, elytris nigro-cyaneis sub- 

 purpurascentibus postice bipunctatis tibiis anticis extua 

 tridentatis. 

 Long. 8 lin., lat. 3 lin. 

 Hab,, South Australia. 

 The above measurement is taken from the largest sized, but 

 most perfect of five specimens in my possession. Probably 

 7 lines is nearer the average length. It is very different from 

 the other species of the group in which its tridentate tibiee will 

 place it. 



Carenum dispar. 



Nigrum nitidum viridi-marginatum sulcis frontalibus sub- 

 parallelis, thorace transverso marginato postice rotundato 

 vix lobato, elytris subpurpurascentibus antice latis subtrun- 

 catis postice bipunctatis, tibiis anticis extus tridentatis. 

 Long. 9 lin., lat. 3| lin. 

 Hab., South Australia. 

 This also differs from the group in which my subdivision of 

 the genus would place it, in its parallel frontal grooves, and non- 

 oval elytra, its transverse broadly margined thoi-ax is however 

 quite in character with the group. 



Carenum ordinatum. 



Nigrum nitidum late atro-viridi-marginatum, sulcis frontalibus 

 divergentibus, thorace transverso postice rotundato sublo- 

 bato, elytris ovatis sei-iatim punctulatis postice bipunctatis, 

 tibiis anticis extus tridentatis. 



Long. 11 lin., lat. 3| lin. 



Hab., South Australia.
