pubescence ; tibial and tarsal spines whitish ; calcaria rufous ; 

 claws for the greater part black. Second cubital cellule about

 Tacky tes monetarms, Smith, Cat. Hyju. Inst. IV., 298. 

 The largest and handsomest of the Indian species, and 

 readily known by the abdomen being covered all over with 

 silky golden pubescence. The antennae have the third 

 joint longer than the fourth, and four times the length of 

 the second. Front and vertex opaque, closely and finely 

 rugosely punctured ; eyes at top separated by a little more 

 than the length of the third antennal joint. Clypeus rounded 

 at the apex. Thorax opaque, closely roughly punctured ; the 

 medial segment much more strongly than the mesonotum 

 and finely and closely transversely striated at the apex. 

 Second cubital cellule at the top nearly one-fourth shorter 

 than the third ; the first recurrent nervure is received about 

 the length of the second cubital cellule from the transverse 

 cubital nervure ; the second is received a little beyond the 

 middle of the cellule. 



The $ has the antennae stouter ; the third joint is 

 distinctly longer than the fourth.

 that of T. ornatipes being elongate and narrow ; the wings 

 have a more decided yellow tint, and the nervures are more
