226 ON THE AUSTRALIAN CLIVIXIBES, 



A comiDletely isolated species among the Australian members 

 of the genus. The external spur of the intermediate tibite is very 

 weak and situated not far fi'om the apex. 



The description given above is founded on specimens (^ '?) from the 

 Clarence River, sent to me by Mr. Lea, which, although appearing to 

 differ slightly from M. Putzeys' description of C. pectoralis in having 

 the puncturation of the head, prothorax, and prosternal ej^isterna 

 weaker, seems undoubtedly that species. One specimen (^ 

 probably), of which only the elytra now I'emain, is much smaller 

 (4-5 mm.), differently coloured^the elytra being black, with the 

 suture and latei'al border reddish — the puncturation of the 

 metasternum and ventral segments stronger, and the ventral 

 segments foveate laterally. In the specimen described above, the 

 puncturation of the prothorax is so obsolete as to require a 

 powerful lens to distinguish it; the metasternum is finely punctate 

 near the sides, also the episterna, and the ventral segments are 

 without punctures or lateral fovetB. A speciriien sent to me by 

 Mr. French, as from West Australia, is of an entirely ferruginous 

 colour. 



P r oc era gr ou j)- 



Size large, or above the average. Clypeus truncate-emarginate 

 (median part truncate, wings projecting strongly forward, and 

 roundly obtuse at apex). Elytra with fourth and fifth striiu con- 

 fluent at base, a submarginal carina at shoulder (sometimes 

 feebly developed, e.g., C. nyctosyloides, Putz.). Prosternum with 

 intercoxal part very wide anteriorly, not sulcate on base. Anterior 

 tibije .3-dentate, external teeth weaker in $ than in $; inner 

 apical spine in $ long, curved, obtuse at apex. 



Fifteen species are associated in this group; of these, twelve 

 known to me, are tabulated below. The group could readily be 

 broken up into seven sections represented by C. frocera, C. monili- 

 cornis, G. ohlonga, C. reynlaris, C. nyctosyloides, C. masters!, and 

 C. maryinata. The .species I do not know are G. elegans, Putz., 

 C. promineris, Putz., and C. obscuripes, Blkb.
