 chest, upper side surrounded with a rim, deeply notched on the hind 

 border, divided by a middle-ridge into two compartments ; front con- 

 tracted in the middle, more widened towards the epistoma, sur- 

 rounded by a rim, and divided by a longitudinal ridge ; sides of the 

 head about half its breadth above: mouth pale luteous: fore-chest 

 short, convex in front, with a deep angular notch on its hind border 

 corresponding to that on the head, surrounded by a rim, having three 

 ridges, the side pair very oblique • three ridges on the middle-chest, 

 the side pair very slightly waved : abdomen obconical, as long as 

 the chest, whitish beneath ; sides and hind borders of the segments 

 green : legs pale green; thighs pale luteous towards the base: hind-
