Head thickly and strongly punctured, with a slight 

 fovea on the vertex. Thorax two-fifths wider than long, 

 gently convex, contracted in front, nearly parallel-sided 

 behind the middle, moderately thickly and strongly jnmc- 

 tured. Elytra a little more than twice the length of the 

 width of the thorax, not broader than the thorax at the 

 base but a little broader posteriorly and then narrowed to 

 the apex ; punctate-striate with the interstices gently con- 

 vex, sparingly and moderately finely j^unctured ; the pos- 

 terior half of the suture and the apex are bright green ; 

 the apex of each elytron is bidentate, the sutiu'al tooth 

 being the longer. The under side of the insect is yellow, 

 with the exception of the prosternum, the middle of the 

 metasternum, the margins of the coxai and abdominal 

 segments, which are bright green.

This species is immediately distinguished from S, 

 limbata by the teeth at the apex of the elytra. Froni 

 S. sa7iguinea it is distinguished, besides the difference of 

 colour, by its shorter thorax and elytra, by the regular 

 striffi of latter, and by the absence of the large ])inictures 

 on the third and fifth interstices, &c. S. Jansom is dis- 

 tinguished by its elongate form, by its uniform green 

 underside, and by the teeth at the apex of the elytra beuig 

 all nearly equal ; the elytra have also a tendency to be
