to the pseudosutiire, this pale line being somewhat impressed; 

 scutum, scutcllum and postnotum brown, the latter rather darker. 

 Pleurae, propleurae and cephalic and dorsal portions of the meso- 

 pleurse, up to the wing-root, j'ellowish ; remainder of the pleura? 

 brownish. Halteres pale, yellow. Legs : coxae suffused with brown ; 

 trochanters light yellow; femora yellow basally, becoming brown 

 at the tip. Wings tinged with grey, stigma elongate-oval, brown, 

 distinct. Venation (see fig. 4, plate IV). 



Abdomen light brownish yellow, the caudal half of the 7th, 

 8th and 9th tergites brown. Hypopygium (see figs. 13-15, plate 

 X) : 9th tergitc, viewed from above, with the lateral ears or lobes 

 prominent, the interval between them almost straight, not deeply 

 notched as in nodicornis; 9th sternite and its pleurite fused, 

 massive, as in the genus, the apical appendate stout, directed 

 ccphalad, flattened at its apex. Viewed from the side, the penis- 

 guard is conspicuous, tripartite as in the tribe, it is very long, 

 arising from the ventral wall, directed caudad and thence dorsad, 

 almost attaining the level of the dorsal edge of the 9th sternite, 

 toward their end, directed ccphalad, the tip flattened; anal tube 

 conspicuous. Viewed from beneath, the massive sterno-pleurites 

 meet in a straight median suture, which is membranaceous; the 

 tripartite penis-guard is deeply concave below the forking.

The difference between the .American and Japanese species arc 

 shown by the following key : 



1. Abdomen brown; cf hypopjgium, 9th tergite with a deep 

 median notch; guard of the penis short, directed caudad. 



(East. U. S.) nodicornis O. S. 



Abdomen reddish brown; cf hypopygium, 9th tergite without 

 a deep median notch between the prominent lateral cars; 



guard of the penis elongate, conspicuous, directed caudad and 

 dorsad, almost attaining the dorsal level (,f the abdomen.
