ORTALID^E — EUMETOPIA. 175 



blackish ; this color, at its inner border, between the third and 

 fourth longitudinal veins, is very pale, and extends sometimes as 

 a gray shadow even beyond the fourth vein ; the first, second, 

 third, and fifth longitudinal veins are conspicuous for their stout- 

 ness and black color; the basis of the second vein and the portion 

 of it lying in the clear spot beyond the stigma, are of a paler color 

 and less stout. The small crossvein is immediately below or but 

 little beyond the end of the stigma; but always beyond the 

 middle of the discal cell; the posterior crossvein is perpendicular ; 

 the last section of the fourth longitudinal vein is conspicuous for 

 its great length and converges gently towards the third ; anal cell 

 with a sharp angle, which is not, however, drawn out in a point.

Gen. XL EUMETOPIA Macq. 



Charact. — Front very much projecting anteriorly, so that the head, seen 

 in profile, appears conical ; upon its sides and its auterior part it is 

 sparsely beset with short, not erect, hairs. 



Antennce of middle size; third joint oval, with a bare arista. 



Face unusually retreating, almost horizontal, below each antenna 

 distinctly excavated and with a small ridge between these impres- 

 sions ; clypeus small, but distinctly projecting over the anterior 

 edge of the mouth. 



Wings narrow and rather long ; stigma very narrow, posterior angle 

 of the anal cell acute ; the last section of the fourth vein somewhat 

 converging towards the third near the tip. 



The species of this genus are always bare, very slender and 

 have a metallic coloring ; moreover, they are easily distinguished 

 by the extraordinary projection of their foreheads and the conical 

 profile of their heads ; the picture of their wings only consists in 

 a more or less extended black spot on the apex.
