Yellowish brown, thoracic dorsum with three almost confluent 

 brown stripes ; brown spots on the metanotum. Antennae pale yellow, 

 darker towards the tip; halteres brownish yellow; abdomen yellowish 

 brown (tip broken). Legs dark brown, but femora paler; a small 

 white ring before the tip of the tibise ; three successive white rings 

 at the end of tarsal joints one, two and three. Wings with a pale 

 brownish tinge; stigma brown. 



Habitat. — Brazil (discoverer, Sellow) ; a single specimen in the 

 Berlin Museum; sex uncertain, as the tip of the abdomen is broken 

 off. The length, when the abdomen is entire, must be about 14 mm. 

 The number of joints of the antennae is certainly more than eleven 

 (this number I counted in T. opilio). 



The above is taken verbatim from Osten Sacken's original descrip- 

 tion ; the type specimen seems to be the only one so far taken.
