ORTALID.E EUXESTA. 167 



the orbits of the eyes, as well as the well-defined ocellar triangle, 

 shining steel-blue. The lateral border of the front shining and 

 generally with a rather distinct steel-blue reflection ; immediately 

 above each antenna, a trace of a small swelling is discernible. 

 The hairs on the front are not conspicuous, moderately dense on 

 the sides, very scarce on the remaining surface. The first two 

 joints of the antennae brownish-black, the rounded-oval third 

 joint reddish-yellow from the basis as far as the arista, more 

 brownish beyond it. Face very much excavated, shining steel- 

 blue, with a whitish pollen on its upper part only ; above this, 

 just between the antenna?, is a conspicuous, velvet-black spot. 

 Clypeus very much projecting, shining, steel blue, pollinose on 

 the margins only. The rather broad orbital circles of the eyes 

 brick-red below, at the lower corner of the eyes. Thorax dark 

 metallic-green, somewhat verging on steel-blue ; the dorsum with 

 a very thin gray pollen. Scutellum blackish-green. Abdomen 

 of the same color as the thorax, but darker, often with a stronger 

 steel-blue reflection ; the last abdominal segments of the male 

 sometimes more bronze-colored. The first segment of the 

 flattened ovipositor metallic-black. Feet black ; the tips of the 

 knees and the basis of all the tarsi brownish-brickred. Halteres 

 white-yellowish. Wings with four black crossbands. The first 

 lies, as in several other species, on and immediately beyond the 

 humeral crossvein and extends as far as the basis of the anal cell. 

 The second band, which is rather broad, begins at the costa with 

 the blackish end of the costal cell and the black stigma ; it is 

 generally very much fainter beyond the fourth longitudinal vein 

 and disappears entirely between the fifth vein and the posterior 

 margin of the wing ; the small crossvein lies almost exactly upon 

 the outer margin of this band. The third band, which is per- 

 pendicular, runs over the posterior crossvein and reaches the 

 posterior margin of the wing almost completely ; it is broader 

 anteriorly than posteriorly, and is connected with the fourth band 

 on the inside of the marginal cell, so that the hyaline interval 

 between these bands extends exactly as far as the second longi- 

 tudinal vein. The fourth band, lying along the apex of the wing, 

 is also rather broad and extends as far as the fourth longitudinal 

 vein. The last section of the fourth vein is distinctly curved and 

 in its second half converges towards the third longitudinal vein.
