Face of the male entirely linear ; that of the female also very 

 narrow, snow-white. Palpi and proboscis dark-yellow. Antenna) 

 bright reddish-yellow ; the small third joint somewhat infuscated 

 at the tip. Front with thick whitish dust ; the frontal bristles 

 black. The cilia of the upper orbit black, those of the lateral 

 and inferior orbits whitish. The upper side of the thorax has a 

 pale, metallic-green ground-color, more copper-colored towards 

 the sides, appears, however, on account of the thick gray-whitish 

 dust, opaque and glaucous. Scutellum more blue-green, but also 

 rather thickly covered with gray-whitish dust ; it has tw r o strong 

 black bristles. The pleura), which are covered with thick white 

 dust, have a grayish-green ground-color, only their posterior mar- 

 gin (ejnmera metathoracis) is of a yellow color. Abdomen some- 

 what less elongated than in the preceding species ; its first seg- 

 ment yellow, usually with a blackish spot on each side, which 

 expands more in some specimens, so that the greater portion of 

 this segment is of a blackish color ; the second segment is also 

 yellow, has however on each side a large, bright, metallic-green 

 spot, which reaches from the posterior almost to the anterior mar- 

 gin and not unfrequently comes in contact with the opposite spot 

 and forms a complete band, so that the anterior margin of this 

 segment alone remains yellows The following segments are on 

 their whole upper side of a very saturate metallic-green coloring 

 and very shining ; towards the lateral margin the color often 

 changes more into gold-green, rarely into coppery. Venter yel- 

 low. *The small rounded hypopygium of the male yellow. All 

 the coxae and the long slender feet pale-yellow ; the stronger hairs 

 and bristles on the fore coxae are fallowish-yellow in the males, 

 black-brown in the females ; the more delicate hairs are pale-yel- 

 lowish in both sexes. Tibiae and tarsi very elongated, especially 

 the fore and middle tarsi of the male, the first joint of which is 

 almost as long as the tibiae and considerably longer than the four 

 following joints together ; in the female, however, the fore and 

 middle tarsi are less elongated, especially their first joint, though
