Scutel- luin generally yellowish, with the exception of its middle. Abdominal segments, with the exception of the last one, with very narrow, but very sharply limited and conspicuous brown posterior margins. The first segment of the very flattened ovipositor is only moderately long, very broad, and very broadly tnnicate at the end; its coloring and its pollen arc similar to those of the abdomen. Feet clay-yellow; tarsi strongly infus- cated, generally paler towards the basis. The first spot upon tlie wings reaches from the first to the fourth longitudinal vein ; the spot upon the end of the stigmatical cell is more or less completely connected with the spot covering the small cropsvein, forming a straight, almost perpendicular half-erossband; tlie other spots have the ordinary appearance.
