segment and on each side a lateral spot, yellow; otherwise, the 

 abdomen is metallic-green, al the basis of the segments handsome 

 coppery-red, altogether covered with a slight whitish dust. The 

 pubescence of the first segment of the abdomen is whitish and 

 delicate, upon the remaining segments it is coarser and black ; the 

 minute black bristles before the second and before the following 

 segments differ but little from the remaining pubescence. Ven- 

 ter yellow, with a very scattered and shorl pubescence, which has 

 near its basis a whitish, towards its end a black color. Fore 

 coxa? yellow with a rather short whitish pubescence and with a few 

 stout whitish-yellow bristles. Middle and hind coxa? likewise yel- 

 low, still the first with a gray spot, which covers the larger pari 

 of its outside. Femora yellow, upon the under side with a hardly 

 distinct whitish pubescence ; the foremost with a single black 

 bristle inserted upon the outside not far from the basis. The 

 middle tibia? have a more distinct minute bristle upon the front 

 side near the basis and a few at the tip, besides some small one, 

 upon the hind side; the hind tibiae have upon the front side, not 

 far from the basis, also one stout bristle and some quite small. 

 hardly perceptible ones upon the upper and under side. Fore 

 tarsi about once and two-thirds the length of the tibiae ; their first 

 joint alone of the same length as the tibiae, brownish-yellow ; the 

 following joints brownish-black and of decreasing length, still the 

 third but little shorter than the second. Middle tarsi once and 

 a-half the length of the tibiae, of the same coloring and structure, 

 only the first joint proportionally somewhat shorter. Hind tarsi 

 but little shorter than the tibia-, brownish-black, at the basis more 

 yellowish-brown, the first joint not quite as long as the second and 

 third taken together. Halteres yellowish ; tegulae with a very 

 narrow black border and whitish cilia. The third longitudinal 

 vein of the wings distinctly curved backwards near its end ; tire 

 anterior branch of the fourth longitudinal vein diverges al a rather 

 acute angle and turns then at a very rounded righl angle tow 

 i he margin, which it reaches somewhat before the apex near the 

 tip of the third longitudinal vein; hind transverse vein Btrikiugl) 

 oblique, not sinuated.
