$. Length rS, 2, to 2 '8 mm. Metallic green to blue-green, shagreened, the sides 

 of the thorax and beneath and the legs more of a bronzed green, the tarsi, except the 

 last joint, pale yellowish, the tibial spurs whitish ; thorax beneath and the legs, except 

 the tarsi, sometimes aeneous-black ; metathorax very short, with a median carina. The 

 abdomen is usually fusiformly pointed, longer than the head and thorax united and 

 usually of a darker colour than the thorax (rarely oval and shorter than the thorax, due 

 probably to the terminal segments being retracted). The wings are hyaline, with the 

 veins brownish-yellow. The antennae are subclavate, the scape and pedicel aeneous- 

 black or metallic, the flagellum brown-black, rather densely pubescent, the funicle 

 4-jointed, the joints rather stout, a little longer than thick. 



$. Length 0*9 to i mm. Very variable in colour, blue-green to bronzed green, but 

 rarely blue-black, the sides of thorax and beneath, and the legs, except tarsi, blue-black, 

 the tarsi, except the last joint, whitish. The flagellum is dark brown, very hairy, with 

 the funicle only 3-jointed, the joints of same being moniliform ; otherwise as in female. 



Comes near O. versicolor Ashm., described from St Vincent, \V. L, but differs in 

 colour, and particularly of the legs and antennae.
