Brassy -green. Front bluish. Antennae of the male rather shorter 

 than the thorax, arista half as long as the third joint. Second and 

 third segments of the abdomen often yellow at the sides, as well as 

 beneath. Femora and tibiae, fore coxae, anterior metatarsi, and base of 

 the hind pair, yellow. Hind legs stouter in the male, with the tibiae 

 and the tip of the femora more spiny, the metatarsus hairy in front 

 and armed at the base beneath with a hooked tooth, divided at the tip into 

 two points ; the femora usually blackish at the tip, sometimes the tibiae 

 also, this colour again extending more largely over them, and occupying
