circular: the tip of the pygidium. linwever, is not brought forward, and the front 

 legs are not longer than the hind ones; characters usually confined to females in 

 the genus. 



Since the above was written two females (from Alexandria in the Northern 

 Territory) belonging to the British Museum have been examined, and these 

 dit'fer from the type in being somewhat larger, and with the apical fovea of the 

 abdomen normally large and round. 



DITROPIDUS STRIATUS sp. nov.

.\s the scutellar lobe is notched, the club five-jointed with the joints rather 

 short and wide and the intercoxal process of presternum wider than long, with 

 its posterior end gently incurved, this species can only be referred to Ditropldus. 

 although it looks out of place in that genus ; at a glance it appears close to 

 Prasonotus latibasis, but that species has the prosternal process longer than wide, 

 and its end deeply incurved. The head and pmthorax are of a rather deep red, 

 the elytra are flavons, with a very narrow black basal edging, the basal space is 

 red with six black spots f including one on each shoulder"), giving it a fasciated 

 appearance, there is a conspicuous black and reddish zigzag fascia at the apical 

 third : the metasternum, four basal segments of abdomen, and the femora are 

 deeply infuscated or black, the club is slightly infuscated. There are ten strong 

 striae on each elytron.
