 seta at each basal angle wanting. 



Table of Genera of the Australian Subtribe Melisoderides. 



i. Prothorax with sides not rounded posteriorly. Elytra with eighth inter- 

 stice narrowly carinate at apex. 

 A. Metepisterna long. 



b, Prothorax with a short distinct narrow ridge between marginal channel 

 and lateral basal impressions. Eyes globular, rising sharply from 

 head at base. 

 C-. Prothorax with three marginal setae anteriorly. Elytra with 7th 



stria entire... Celamda. 



cc. Prothorax with- one marginal seta anteriorly. Elytra with 7th 



stria obsolete, except on apical fourth Melisodera. 



bb. Prothorax without any submarginal ridge near basal angles. Orbits 

 oblique behind eyes. 

 d. Antennae moniliform. Prothorax short. 



e. Anterior tibiae with external side feebly arcuate; intermediate not 



arcuate Moriodema. 



ee. Four anterior tibiae arcuate Moriomorx>ha . 



dd. Antennte slender. Prothorax rather long (3 'S x 3 '7 mm. ). Inter- 

 mediate tibiae only strongly arcuate Rlia'bolestus, n.gen. 



AA. Metepisterna wide and short. 



/. Antennae moniliform Phersita, n.gen. 



ff. Antennge slender Tropopterus ?* 



ii. Prothorax with sides rounded posteriorly. Elytra with 8th interstice not 

 carinate at apex (except in Cyclothorax curtus, SI.) MecyclotJiorax.i 



The genus Cyclothorax (Macleay, 1871) must be deleted from 

 the Carabidce, having been proposed previou.sly in the Class 

 Arachnida (Frauenfeld, 1868), and it seems to me that its place 

 may be taken by Mecyclothorax, which Dr. Sharp says only differs 

 by the "atrophied wings from the antipodean genus Cyclothorax." 

 I do not look upon this character as truly generic in itself
