 apicem obsoletis, spatio laterali crebre subtilius punc- 

 tulato transversim rugato, lateribus pone medium serratis ;; 

 pro et metasternis disco sparsim subtilius, versus latera 

 crebre crasse, punctulatis, illo antice transversim fortiter

 crebre, squamose punctulato. Long. 5-| — 7^1. 



I know no species previously described bearing much resem- 

 blance to this. The six raised interstices between the striae on 

 the elytra and the wide space outside them free from distinct 

 striation and transversely wrinkled, together are sufficient to 

 characterise the insect. The external non-striate space is in 

 some specimens a little copper coloured. The apical segment 

 of the hind body is of the structure usual in Melohasis. 



I owe my type to the liberality of Mr. J. Anderson, who cap- 

 tured it near Port Lincoln. There are two specimens in the 

 South Australian Museum, and I have seen a fourth taken by 

 Mr. Eothe, near Sedan. In the last-mentioned example the- 

 curve of the apical portion of the lateral margins of the elytra 

 is somewhat sinuate.
