 larged, third shorter than fourth and fifth combined, third 

 to seventh cylindrical, eighth to tenth shorter and thicker, 

 eleventh oval. Prothorax (2 x 3'5 mm.), with apex pro- 

 duced slightly in the middle and strongly so at the acute 

 anterior angles, base slightly sinuate, not much wider than 

 apex, sides with basal half nearly straight, anterior half

 smooth medial line; lateral margins evident from above. 

 Scutellum black, triangular smooth. Elytra considerably

A single specimen in the Melbourne Museum is differen- 

 tiated from all described species by its combination of black 

 prothorax, legs, antennae, and tarsi, and bright vari- 

 coloured elytra. The strongly produced anterior angles and 

 nearly straight sides of prothorax (shaped somewhat like Chal- 

 copterus purpureus, Germ.) are distinctive. The elytra are 

 sculptured somewhat as in G. variabilis, Bless. Type in the 

 Melbourne Museum.

 the sides.
