 crenulate ; disc with wide smooth medial convexity, with 

 narrow sulci on each side of this terminating in a rugose 

 space towards front angles, and three large depressions near 

 margins (one near posterior angle) and smaller round foveae, 

 irregular in size on other parts of disc. ScuteXlum small,

A single female specimen from the French Collection in 

 the Melbourne Museum is quite different from all described 

 species, and may be readily distinguished by the combination 

 of large size, violet-blue colour, slightly-raised costae, wide 

 marginal vitta, and irregularly spotted surface. Type in the 

 National Museum, Melbourne.
