rather broad reddish-brown appendages the ends of which are fringed with shorter 

 yellow hairs ; hypopygium very dark brown ; upper lamella thick, swollen, with a 

 median shallow furrow which is much narrowed anteriorly, posterior margin produced 

 into two short, blunt swollen processes which are widely separated by a deep rounded 

 incision, below these is another pair of flattened, triangular, sharper pointed processes; 

 the posterior half of the suture separating the upper from the lower lamella quite 

 wide, membrane whitish ; lower lamella with a rounded incision which is filled with 

 the broad bases of a pair of long triangular upward pointing appendages ; outer upper 

 appendages very long and slender ; wings hyaline ; costal and subcostal cells yellow- 

 ish ; fifth longitudinal vein with a narrow very faint yellowish border ; stigma brown ; 

 the whitish band beginning in front of the stigma extending through the discal into the 

 base of the fourth posterior cell ; a whitish spot beyond the stigma ; discal cell hardly 

 twice as long as wide. Length, male 21 mm., wing 22 mm.

 abdomen, first three joints yellow, others light brown, much darker at the base which 

 js somewhat incrassate ; mesonotum light yellow with three brown stripes, the median 

 one twice as broad as the lateral ones and indistinctly divided by a faint cinereous

 darker brown ; collare light yellow with three faint brownish spots ; scutellum and 

 metanotum light yel'ow, each with a very faint median brown line ; pleura whitish ; 

 halteres yellowish, knobs brown ; legs yellow, tarsi and the tips of the femora and

 lateral lines somewhat sinuate, lateral margin of each segment broadly whitish ; eighth 

 sternite dark brown, somewhat lighter posteriorly, posterior margin truncate with a 

 median rather broad, blunt, rectangular reddish process; lateral angles with a pair of 

 long, rather narrow, flattened appendages the inner margins of which are furnished with 

 a few yellowish hairs ; hypopygium large, very dark brown ; upper lamella thick, 

 swollen, with a median shallow furrow which is not narrowed anteriorly, posterior 

 margin produced into two rather long, blunt, rounded processes which are separated by 

 a deep, V-shaped incision ; wings hyaline, faintly darker toward the tip ; costal and 

 subcostal cells faintly tinged with yellow ; stigma brown ; the posterior cross vein and 

 the portion of the fifth longitudinal vein beyond this vein with a faint very narrow 

 brownish border ; a broad whitish interrupted line beginning in front of the stigma and 

 extending across the discal cell into the base of the fourth posterior cell ; a small 

 whitish spot beyond the stigma ; discal cell twice as long as wide. Length, male 21

Very similar to T. hirsuta, but easily distinguished by the structure 

 of the eighth abdominal sternite and the upper lamella of the hypo- 

 pygium.
