smooth and bare ; the base of the mandibles covered with 

 golden pubescence; the palpi are covered with a pale pile. 

 Pro- and mesothorax thickly covered with bright golden 

 depressed pubescence ; the median segment with pale 

 fulvous hair. The basal portion of the median segment 

 is closely transversely striated ; the transverse striae are 

 irregularly intersected by longitudinal ones ; on the basal 

 half in the centre is a longitudinal one ; the apex has an 

 oblique slope, is irregularly transversely striated, in the 

 middle is a deep furrow. Propleurae shagreened, covered 

 with pale fulvous pubescence ; the mesopleurae closely punc- 

 tured and thickly covered with rufo-fulvous pubescence, 

 intermixed with long pale fuscous hair, as are also the 

 metapleurae and the mesosternum. The mesosternal furrow 

 is narrow and shallow ; the transverse furrow at the middle 

 coxae is deeper and wider; the metasternal process is nar- 

 rowly, but distinctly, furrowed down the middle; the apex 

 is divided into two somewhat triangular processes. Legs 

 densely covered with a golden pile ; the hinder tibiae are 

 distinctly keeled in the middle behind ; the calcaria black ; 

 the tibial and tarsal spines bright rufous. Wings yel- 

 lowish hyaline, the apex slightly infuscated ; the nervures 

 and stigma yellow; the first cubital cellule at the top is 

 hardly one third of the length of the second ; the first 

 transverse cubital ncrvure is broadly curved ; the two 

 recurrent nervures are united near the top, shortly appen- 

 diculated, and are received near the apex of the basal third. 

 The basal three abdominal segments are covered with 

 depressed golden pubescence; the pygidial area black, 

 sparsely covered with golden hair ; the hypopygium is 

 closely and distinctly, the penultimate segment sparsely, 

 punctured. The lateral folds on the inner orbits are promi- 

 nent ; the sculpture of the front and vertex is hid by the 

 dense pubescence ; the frontal furrow appears to be wide 

 and shallow. 



Allied to T. Saundersi and T. Rothneyi, but is quite 

 distinct.

Scape of antennae (except above) thickly covered with pale
