Whigs ting-ed with yellowish: proximal half brownish, which color is 

 especially distiiict in tlie first basal cell, from which it extends and be- 

 comes gradiially evanescent, towards the costa, the discal and the third 

 posterior cell. There are faint, small, grayish clonds at the tip of the 

 auxiliary, tirst and second veins and also about the middle of the last 

 section of the 3. and 4. veins. Length, about 4 mm." 



L. c. p. 221: Front and vertex broad, even, nearly flat; about as 

 broad as each eye; a little narrowed, anteriorly, not swollen above the 

 lunule; the space on each side, between front and lunule, very narrow: 

 profile not projecting-; ocelli near the edge of the vertex. 2 pair of verti- 

 cal bristles; no other cephalic bristles. Arista microscopically pubescent. 

 Thorax broader than long; the lateral transverse sutures are very 

 near the humeri, ending on each side in a feeble longitudinal furrow. — 

 Abdomen short and broad, fmely pubescent, but without bristles; con- 

 sisting apparently only of two segments; the first is transverse and vi- 

 sible on the sides of the scutellum only (das basale Doppelsegment); the 

 second occupies the remainder of the upper side of the abdomen and is 

 nearly as long as it is broad, convex, smooth; under it, the short basal 

 Segment of the ovipositor, with its protruding second segment. In the 

 specimen which I take for the male, the 2. segment seems to be less large, 

 and a third, short segment is distinctly visible under it. 



Wings: Costa and first vein distinctly hairy; the 3. is glabrous. 

 Auxiliary in close contact, with the first; is ending rather instinct. The 

 first vein ends nearly opposite the posterior crossvein; the 2. soon after 

 it; the bifurcation of second and third takes place about the middle of 

 the length of the wing; anterior crossvein very short; second basal cell 

 unusually broad and long, reaching beyond the middle of the wing; as a 

 consequence, the discal cell is shortened and nearly Square; anal cell cut 

 off Square at the end; alulae large. The wings are not expanded horizon- 

 tally, their distal half being somewhat beut (as in Stegana).

 zijde van de bijoogen (even als in A^. platessa O.-S.) eeine glanzige vlek,

 schildje en achterlijf glanzig zwart, met nauwelijks merkbaren blauwen
