with dark sides, sometimes middle of breast dark, legs entirely dark 

 except the pale coxae and sometimes tibiae with a light streak; lightly 

 pubescent; hind femora with fine pubescence. Length 5.5 to 6.5 mm., 

 width 2.9 to 3.4 mm. 



Type: Not located (not in Berlin). The species was described from 

 a specimen from Buenos Aires.

 Brazil with a Chevrolat name. 



Remarks: I have been unable to find the w^hereabouts of the type 

 of this species and it may be lost, although the type of D. conjuncta 

 (Germar), described at the same time, is in Berlin. Harold, writing 

 in 1875, stated that D. copulata was unknown to him. Thus, I am 

 uncertain whether the insect described above is really D. copulata, 

 but of several closely related species from Argentina this best corre- 

 sponds with Germar's description. He described the thoracic markings 

 as a spot on the disk composed of three confluent ones making a crown 

 in reverse (''corona reversa"). The thoracic markings of this and 

 D. prolixa Harold might be interpreted as a "corona reversa," but 

 the undersurface of the latter is not dark as described by Germar.
