Aastfaliaii and Tasiaanian Colcoplera. 2Zl 



auteiinal joints were not counted ; the extremely curious pro- 

 thoracic sculpture being identical. The clothing on the upper 

 surface is scarcely perceptible, and the minute punctures on 

 the elytra! intei-stices are very indistinct. 



Di pJocotes sfrif/irolhs, n.sp. 



Reddish castaneous ; legs and club somewhat paler. With 

 fairly numerous, pale, short, stiff setae, becoming lineate in 

 arrangement on the elytra. 



Head as in two preceding species. Antennae extending to 

 middle coxae, first joint stout and very little longer than 

 second, second slightly longer than third, third to eighth equal 

 in width and subequal in length, ninth inflated, subovate, 

 almost as long as three preceding joints combined, tenth 

 slightly narrower and about half the length of ninth, its apex 

 truncate and densely pubescent. Prothorax slightly longer 

 than wide ; each side just before middle produced into a small 

 acutely angular tubercle, and at basal third notched ; densely 

 longitudinally strigose ; transversely impressed at basal third, 

 and feebly depressed (but not foveate) in middle of depression. 

 Elytra Ijriefly ovate, strongly convex ; with regular rows of 

 moderately large but shallow punctures ; interstices finely 

 punctate, not separately convex. Abdomen densely longitudin- 

 ally strigose. Legs moderately long. Length 1;^ mm. 



Hah. — S. Australia (type in Australian Museum). 



In general appearance like a small setose specimen of the 

 preceding species, and also with ten-jointed antennae, but the 

 club comparatively much wider, and the prothorax with a shal- 

 low submedian impression instead of a deep fovea. 



Tfie species known to me may be taijulated as follows: — 



Antennae ten-jointed. 



Prothorax with a very lari;e fovea - decemarticulatus, n. sp. 



Prothorax without such a fovea - - - striyicollls, u. sp. 



Antennae eleven jointed.
