A specimen from Barrackpore, and another from Tir- 

 hoot, are probably referrable to this species. The antennit^ 

 are covered with a pale microscopic down ; the third joint 

 is a little longer than the fourth, and three times the length 

 of the second. Eyes at the top separated by the length of 

 the third antennal joint. Vertex and front almost shining, 

 finely rugosely punctured. Clypeus punctured, the apex 

 depressed, broadly rounded, entire. Thorax closely punc- 

 tured all over ; the median segment transversely punctured,, 

 the apex transversely striated, deeply furrowed down the 

 centre. Abdomen aciculated, punctured closely and finely 

 towards the apex. Pygidial area elongated, sharply pointed 

 at the apex. Ventral surface shining, sparsely haired,, 

 aciculated, the apical segments punctured laterally. Wings 

 yellowish hyaline, the nervures yellowish testaceous ; the 

 second cubital cellule one-fourth longer than the second ; 

 the first recurrent nervure is received about the length of 

 the top of the second cubital cellule from the recurrent 

 nervure ; the second about the same distance beyond it, 

 and before the middle of the cellule. The tarsi are only 

 red at the apex. 



T.fervidus, Sm., is the only other known Indian species, 

 with red abdomen, but it has the legs reddish.
