This species varies much, but may always be distinguished by 

 the two broad green bands on the back of the thorax, which are 

 securiform behind, and below which three black or green spots in 

 an oblique series are always visible. In the less adult specimens 

 the pterostigma is yellow, and the abdomen is yellowish towards 

 the extremity and on the sides. In the most adult specimens 

 the pterostigma is blackish, and the abdomen is almost entirely 

 bronzy black above, even the anal appendages being blackish. 

 The postnodal cross-nervures vary from 10 to 13.
