colour; tlic base of tlio JuaiuliMes covered with <le|)rc.sse<l 

 golden piihe.scence. Tlionix l)lnck ; the tubercles rufous, 

 covered with short golden pubescence ; the inesonotum 

 alutaccous; the nietanotuin and the pleurje closely and finely 

 |)unituri'd. Legs rufous, the coxie broadly black at the base. 

 Wings hyaline, with a slight fuscous tint; the apex of both 

 wings smoky, the cloud commencing near the end of the 

 radial cellule ; the first cubital cellule is half the length of 

 the second; the first transverse cubital nervure is sharply 

 elbowed and bullated shortly below the mifldle, and is united 

 to the first recurrent nervure. The basal three segments of 

 the abdomen arc rufous, marked with black on the apices, th»; 

 third more broadly than the others, the fourth is still more 

 broadly black ; the last segment is rufous, suffused with 

 black, and is strongly and closely punctured ; the pile is 

 golden. The ventral surface is similarly coloured but more 

 suffused with bhick. 



Comes nearest to T. Yerbia-i/i, Bingham. Characteristic 

 is the interstitial first recurrent nervure, a feature which does 

 not occur in any of the other Oriental species. The apex of 

 the radial nervure too is rounded, not straight or oblique as 

 in most species ; the appendicular cellule is almost obsolete, 

 the nervure being almost obliterated.
