 of the prothorax. Head smooth, with a transverse furrow behind the lip 

 of the vertex, which is elongate-conical ; front roughly punctured, with 

 lour yellowish dots; inner keels apparent only between the antennae; outer 

 keels* very slight, diverging towards the face; sides and face yellowish.

 purplish red. Prothorax punctured ; hind border elongated, conical ; 

 several yellowish marks on each side. Prosternal spine green, transverse, 

 acute, rather long. Pectus green, with some small brown marks. Abdo-

 shorter than the hind femora, their spines with black lips. Fore wings 

 green, rather shorter than the abdomen, with a ferruginous black-bordered 

 costal stripe. Hind wings blackish; veins black. Length of the body 

 17 lines; expansion of the fore wings 22 lines. 



This species seems to be different from T. octomaculatus, for in the

 thorax nor of the costal stripe of the fore wings.
