This is a very common insect. Many writers have written 

 about it. I refer the reader to Spaeth's Catalogue, p. 52. 



Boheman, Mon. Cassid. ii. p. 99, distinguishes S. nebidosa 

 thus : — " S. spi7iifex minus lata, magis convexa, prothoracis et 

 humerorum structura, necnon elytris apice sub-rotundatis, ab ilia 

 abunde distincta." Having examined 28 examples of nebidosa 

 and spinifex in the collection of the British Museum, I am of 

 opinion that they must be regarded as the same species and 

 that characters mentioned by Boheman cannot distinguish them.
