 and front of thorax spotted with yellow, pronotum with a broad 

 lateral submarginal streak ; tips of humeral horns and terminal 

 process black ; tegmina pale horn yellow, the veins and an 

 apical spot slightly darker. Length of pronotum 1 ] , width at

This is the liemiptyedia centrotoides of Walker's List ; but it 

 differs from that species not only in colour but in structiu'e, 

 the front margin of the pronotum being regularly convex and 

 the humeral horns perfectly continuous with it, so that, instead 

 of being slightly inclined ujnvards, they take a downward curve.
