Head brick-red ; . the little stripes running down from the 

 vertex and the region of the ocelli steel-blue, rather shining; the 

 larger portion of the occiput blackish, with a grayish-white pollen. 

 The front is of only moderate breadth ; the hairs upon it are 

 strikingly coarse, more dense upon the pollinose lateral borders, 

 scarce upon the remainder of the surface. Antennas brick-red, 

 third joint rounded-oval, towards its end brownish and more so 

 on its outer than on its inner side. The face is very moderately 

 excavated ; the clypeus moderately projecting, both with a steel- 

 blue reflection and a white pollen. Thorax of a very dark color, 

 verging sometimes on green, sometimes more on steel-blue or 

 violet, and always covered with a rather dense whitish pollen. The 

 scutellum is of a still more dark violet-black color, and less polli- 

 nose. The abdomen is of a metallic, but very dark bluish-black 

 or violet-black color. The first segment of the flattened ovipositor 

 is generally still darker. Fore coxae, with the exception of their 

 basis and the tip of the hind coxas, brownish-brickred, the former 

 with a white pollen. Femora black; the first pair, and generally 

 also the last, more metallic-black; all are brownish-brickred at 

 the tip; tibiae blackish-brown; dark brick-red at the tip and often 

 also at the extreme root; tarsi brick-red at the basis, blackish- 

 brown towards the tip. Halteres clay-yellow. Wings hyaline, 

 with four black crossbands. The first lies upon and a little 

 beyond the humeral crossvein and reaches the hasis of the anal 

 cell ; the second begins at the anterior margin with the but 

 moderately long, black stigma and the blackened extreme tip of 

 the costal cell : it is perpendicular and reaches beyond the fifth
