I have divided the Australian species of Clivina into thirteen 

 groups; a synoptical view of these groups is given in the table 

 below. The groups are formed in an arbitrary way, and no doubt 

 their number might advantageously be reduced had J a surer 

 knowledge of the affinities of the species. 



Tahlt (jroupinc) the Aus',ralia7i ■•<2)ecifii of Clivina. 



I. Elytra with strife free at base. (Subniarginal humeral carina wanting). 



A. Facial sulci simple, clypeus emarginate; inter- 



coxal part of prosterniim wide anteriorly..., biplagiata group. 



AA. Facial sulci recurved, clypeus with median 

 part angular; inter-coxal part of prosternum 

 very narrow anteriorly cribrosa group. 



II. ?]lytra with four inner striiB free at base, fifth joining sixth at base. 



(Submarginal humeral carina normally present). 



B. Mandibles short. 



C. Clypeus with five triangular projections in 



front V coronata gco\\\i. 



CC. Clypeus with median part more or less 



angular laterally ohliquata grou p. 



BB. Mandibles long, decussating. 



D. Prothorax with border reaching base on 



each side planiceps group. 



DD. Prothorax with border not reaching base r/randiceps group. 



III. Elytra with three inner stritB free at base, fourth joining fifth at base. 



(Submarginal humeral carina usually well developed). 



E. Clypeus with median part more or less dis- 

 tinctly divided from wings along anterior 

 margin (usually more prominent than 

 wings). 



F. Anterior femora with posterior edge of lower 



side strongly dilatate in middle punctaticeps group. 



FF. Anterior femora not greatly dilatate on 

 lower side. 



G. Head very wide across occiput, eyes not 

 prominent.
