Uracanthus pallens, Hope. 

 PI. xxxii., fig. 28. 

 The original description of this species (excluding size, 

 which in the genus is very variable) would fit several species, 

 but as it was from Tasmania it is probable that a specimen 

 from the Blackburn Collection (bearing a label that is similar 

 to that of many Tasmanian specimens in his collection) may 

 belong to it. This specimen is close to simitlans, but the 

 spines at the tips of its elytra (fig. 28) are somewhat different 

 to those (fig. 22) of that species. 



Uracanthus bivittatus, Newm. 



PL xxxii., figs. 29 and 30. 



A fairly common species in New South Wales and South 



Australia. On some specimens the lines of clothing on the 



pronotum are continuous to the apex and closer together than 



on the typical form; but this may be sexual. 



Uracanthus froggatti, Blackb. 



This species was described as having the apex "of elytra 

 truncate and devoid of spines," but not correctly so, as two 

 co-types in the Museum have the tips of elytra densely 

 clothed with snowy pubescence, concealing their real sculp- 

 ture; the tips themselves are emarginate, with the sides of 

 the emargination lightly spinose, or at least acute; the elytra 

 just before the tips are each conspicuously semi-circularly 

 depressed.
