 Elytra orange-coloured, with the apical third black. Abdo- 

 men checquered black and ash-coloured, middle and sides alter- 

 nating in colour. Legs with the thighs black, which may be

 subquadi-atam, ultra scutellum postice fere cruciformi), dimi- 

 dia parte apicali (notulis tribus viridibus signata, duabus 

 transverse positis, tertia virguliformi infra fere ad maculam

This species much resembles in its coloration T. Gicerinn, 

 White {T. scenica, Dej.), but it differs in the design on the 

 elytra. Head velvet-black, with two longitudinal green lines 

 which start from the exterior angle, course along the eyes, are 

 united between the antennte, and are prolonged along the 

 sides of the thorax to its base. Mandibles green on the side, 

 black and smooth at the point. Antennas of the length of the 

 body, black. Thorax velvet-black, straight in front, shortly
