each becomes a little broader than its predecessor, eleventh ovate, 

 shorter than the preceding two. Prothorax longer than broad, narrow, 

 cordiform, emarginate at base, finely margined. Scutdlum strongly 

 carinated longitudinally. Elytra about as long as broad, with fine rims, 

 each obliquely truncated behind towards the suture. Abdomen strongly 

 margined laterally, moderately elongate, somewhat attenuated at base 

 and apex. Legs very long and slender, simple ; tarsi filiform, very 

 slender, pentamerous, the posterior not much shorter than the tibiae.

 behind the scutellum, distantly punctulated; shining, of a pale, or dark, 

 bronzy-brown colour. Abdomen glossy, the third and fourth segments

 fourth and fifth blackish, the others dark rich reddish-brown. Legs 

 castaneous, pale or dark, very long and filiform ; tarsi reddish-tes-
