about midway between the coxa and the pseudo suture; ovipositor 
about as in macrosterna; upper valves tipped with black; lower valves, 
viewed from the side, broad at the base, the ventral margin concave,

of the stigma; Rs short, less than twice as long as the deflection of 
Rais; Rois short, forming the caudal margin of the stigma; R» short,
