Deep metallic green, with a large orauge spot on the front half 

 of each elytron and a still larger one on the posterior half, the 

 Jatter usually occupying almost the full breadth of the elytron. 



It is a very large insect, elongate in shape, slightly narrowing 

 behind, very smooth and coriaceous above. The clypeus rugose, 

 the margins reflexed, the sides straight and very slightly diverging 

 towards the front, and the front margin nearly straight. The 

 pygicUum is very finely rugose, tbe metasternuni rugose and setose, 

 and the mesosterwd process short and bluntly angular at the end. 



S . The clypeus is granulated and without distinct punctures, 

 and the angles are rather sharp. The prothorax is swollen above, 

 longer than that of the female and a little narrowed towards the 

 base, its surface being less shining and more coriaceous. The 

 front legs are greatly elongated, with the tibiae strongly but 

 irregularly tuberculated beueath and the terminal external tooth 

 very feeble and blunt. The fringe at the inner edge of the 

 •middle and hind tibite is close but short, aud the middle tibiae are 

 not toothed externally. The abdomen is broadly impressed along 

 the middle beneath. 



Lenytli 37-46 mm. ; breadth 19-23 mm.

Deep bronzy brown or green, with a yellow margin at each side 

 •of the pronotum, and a round anterior spot aud a lunate posterior 

 ■ one, of the same colour, on each elvtron. 



The form is moderately elongate, with the elytra scarcely 

 narrowed behind. The head and clypeus are rugose, the prothorax 

 strongly punctured, the scutellum punctured at the sides, and 

 the elytra finely rugose, except in the scutellar region, where 

 •they are strongly punctured. The pygidium is finely rugose, the
