In most Collections. 



This insect, which appears to be the most common in the genus, 

 is sent in most collections from South Australia ; it differs from 

 the last in having thicker antennge, and in the relative length of 

 the third and fourth joints ; the sides of the elylra are rather 

 less parallel,

Elongata, fusco-aenea ; subtus nigra, thorace lateribus punctate, 

 elytris punctato-striatis.

Elongate, the elytra more convex than in the last species ; the 

 thorax has a steel-blue tint, and the elytra occasionally a metallic 

 green reflection. Antennae black, stouter than in the two pre- 

 ceding species, half the length of the body, third and fourth joints 

 equal. Head and palpi black, the former finely and remotely 

 punctured ; clypeus separated from the face by a deep groove. 

 Thorax twice as broad as long, sides slightly rounded, coarsely 

 punctured, disc smooth and shining, slightly convex, with a few
