70 ON THE SCARITIDiE OF NEW HOLLAND, 



Antennce capite vix longiores, gracillimas, articulis 2'^°- et 3"°-, 



subaequalibus et sequentibus longioribus. 

 Pro)iotum convexum, postice parum lobatum. 

 Elytra e pronoto pedunculo brevi subremota convexa, apice 



baud truncata. 

 Pedes breves, sat robusti ; tibiis anticis extus dentatis, intus 

 emarg-inatis et calcaratis, tibiis intermediis ad apicem in 

 spin am externe productis. 

 I have quoted Mr. Westwood's description of this genus in 

 ftdl, as I am unable myself to give any information about it. 

 I have never to my knowledge seen a specimen of it. It was 

 founded on two species from Port Essington, and Reiche has 

 since described two species from Swan River. 



The chief distinguishing features of the genus seem to be 

 its unarmed mandibles, porrected labrum, and mentum without 

 any medial tooth.
