second and third segments ; they gradually become indistinct on 

 the sides and finally disappear near the lateral margin. The 

 fifth segment of the female abdomen is very much shortened. 

 The first joint of the ovipositor is shining-black, with black hairs, 

 about as long as the penultimate segment of the abdomen, not 

 very broad, and, towards its end, rather narrowed. Eeet brick- 

 red; tarsi infuscated towards their end, the front ones much more 

 than the four posterior ones; the front tibiae also show sometimes 

 a browner coloring. Wings grayish-hyaline, quite gray towards 

 the posterior border, not very transparent; more yellow towards 

 the basis, especially in the costal cell ; stigma ochre-yellow, with 

 a somewhat infuscated end. The picture of the wings is brownish- 

 black; it comprises: 1, a spot upon the humeral crossvein, 

 reaching as far as the fourth longitudinal vein ; 2, a perpendicular 

 crossband, covering the end of the costal cell near the anterior 

 border, and reaching posteriorly as far as the sixth longitudinal 

 vein ; between the fifth and the sixth longitudinal veins it is much 

 paler and disappears gradually in the gray coloring of the surface 

 of the wing; 3, a perpendicular half-crossband, beginning near 

 the anterior margin, immediately beyond the end of the first 

 longitudinal vein, running over the small crossvein and reaching 

 a little beyond its posterior end ; 4, a spot, broadly covering the 

 posterior crossvein in the shape of a half-crossband ; 5, a spot 

 occupying the end of the marginal cell and, with the end nearer 

 to the root of the wing, reaching into the submarginal almost in 

 the shape of a hook, without touching the third vein; 6, a spot 

 near the apex of the wing, the limit of which runs almost perpen- 

 dicularly from the end of the second longitudinal vein to the 

 fourth longitudinal, beyond which it occupies only a small space 

 at the extreme end of the second posterior cell.
