bristle at the middle and another one just before the tip, without distinct 
setulæ above. Wings hyaline, the costal vein extending to about two- 
fifths of the distance to the wing tip, its bristles rather stout and close. 
First vein close to the third until near its tip, the two ending rather 
close together ; fourth vein suddenly strongly recurved near its tip ; fifth 
nearly straight, ending nearer the wing tip than the fourth ; seventh 
indistinct. 
Described from a single male specimen collected at Yilcanota. 
The species is readily distinguished from other membres of the 
genus by its color and the chætotaxy of the legs, as well as by the 
shining front and thoracic dorsum.
