74 JS'KW AUSTRALIAX ASILID.E, 



the two species are really very distinct. C. pitnctatiis is a 

 deep black species, without a trace of red, and with very 

 distinct white lateral spots, whereas C. rtihidi pennis is dis- 

 tinctly a reddish species, and the lateral spots are pale red- 

 dish and inconspicuous ; the difference is very perceptible in 

 the thorax, which in G. ruhidipcnnia is a deep claret-red 

 instead of bla.ck, and the legs are also red-brown instead 

 of black; C. ruhidipennis is also a slightly larger species. 



G. ruhidijyennifi is at present known from a single 

 specimen taken by Mr. F. P. Spry in Victoria. 



Brachyrrhopala, Macq. 



Of this genus, characterised by the club-shaped abdo- 

 men and anterior tarsi with a terminal curved spine, six
