 from base to apex ; metacarpus as long as the stigma ; the radius per- 

 pendicular to the anterior margin of the wing, and about as long as 

 the transverse cubitus ; abdomen rather slender, strongly compressed ;

 little broader than the second tergite is long down the middle, smooth 

 at base, ruguloso-striate on the posterior two-thirds; second tergite 

 small, as broad at base as first tergite is broad at apex, and much

 and entirely rugulose; the membranous margins on the two basal 

 abdominal tergites very broad; the third and following tergites 

 smooth and very shining; hypopygium not projecting beyond the 

 apex of the last dorsal segment ; ovipositor sheaths more than one- 

 third the length of the abdomen, and narrowing gradually toward 

 tip. Mostly black; antennal scape yellowish; remainder of the an- 

 tennae dark brown or black; tegulae pale yellow; wings slightly 

 clouded, the veins and stigma brown; legs entirely, including all
