and of uncliaracterized species of Halticlnce. 317 



impunctate, finely rugnlose ; intei'ocular spaces impressed 

 Avith a few large round punctures, separated from the front 

 on either side by an oblique flexuose groove, the lower end 

 of which is connected with its fellow of the opposite side 

 by the transverse groove separating the apex of the clypeus 

 from the upper face ; encarpa^ and carina obsolete ; clypeus 

 short, very broad ; labrum large, its anterior margin ol)- 

 tusely angulate ; mandibles large ; antennas scarcely half 

 the length of the body, five or six lower joints piceous, 

 the rest black. Thorax nearly three times as broad as 

 long ; sides straight and parallel at the base, thence very 

 slightly converging to the apex, the anterior angles \)vo- 

 duced laterally into a very short subacute tooth ; middle 

 third of apical margin slightly sinuate ; above subcylindri- 

 cal, impressed on either side at the base, with a shallow, 

 slightly oblique, longitudinal groove, which extends up- 

 Avards on the disk for a fourth of its length ; surface very 

 finely granulose-rugose, nitidous, finely punctured, the 

 ]3uncturing and rugosity more distinct on the sides. 

 Elytra scarcely broader than the thorax at the base, 

 attenuated from before the middle to the apex, convex, 

 regularly and deeply punctate- sti-iate ; interspaces plane, 

 convex on the outer disk, sparingly impressed with very 

 minute punctures. Legs short, robust, basal joint of 

 hinder tarsus dilated in the $ . 



Separated from C. oenea, Waterhouse, by its smoother 

 head and thorax ; fi'om nvjro-mnea of the same author, by 

 the smoother thorax and by the basal thoracic grooves. 



Chatocnema brevicornis. 



Anguste ovata, convexa, nitida, subtus nigra, supra 

 cuprea, pedibus antennisque rufo-fulvis, his extrorsum 

 nigro-piceis, femoribus posticis cupreis ; thorace granu- 

 loso, minute, subremote punctato ; elytris ovalibus, sat 

 tenuiter punctato- striatis, interspatiis planis, granulosis. 



Long. 1 lin. Hab. — Western Australia. 



Head subrotundate ; vertex and front granulose, finely 

 punctured ; grooves separating the front from the inter- 

 ocular sj)aces distinct ; clypeus plane, more coarsely 

 punctured than the front, its apex broadly truncate ; 

 antennaj slender, much less than half the length of the 

 body, rufo-fulvous at the base, the seven outer joints 

 nigro-piccous. Thorax twice as broad as long ; sides
