 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-
