18 Mr. H. W. Bates on the Longicorn 



well-known Austriilian insect. White gives it on the authority 

 of Dr. Sinclair.

This new genus is founded on CalUdium zealandicum 

 (Blanch.), an insect having no near affinity to Calliclium, but 

 which Lacordaire was inclined to place in CaUidiojosis^ and 

 White included in CEmona. It differs in essential characters 

 from all those groups, and seems most nearly allied to the 

 American genus Elaphidion.

Rusty brown in colour, with paler pubescence ; the smooth 

 streaks on the thorax consist of a dorsal line and two dis- 

 coidal ones on each side, the inner of which is connected with 

 a rounded tubercle, and the outer short and sometimes obsolete ; 

 the elytra are rugose-punctate throughout.
