 tles ; antennae livid j face and orbits mostly yellow ; scutellum 

 unarmed, yellow, completely bisected by a longitudinal black 

 line ; legs yellow ; hind femora and base of hind tibia? blackish, 

 the former mostly yellow above and below, and armed be- 

 neath with numerous small teeth ; abdomen subsessile, rather 

 long and pointed, with three interrupted transverse yellow 

 lines ; wings subhyaline, with yellowish nervures. In a 

 second specimen the yellow markings are more extended, the 

 thoracic sutures being marked with yellow, and the pleura? 

 also with small irregular yellow markings ; the hind femora 

 are yellow, black at the tip, this colour extending to the base 

 of the hind tibia? ; and there is a large blackish blotch in the 

 middle, hardly connected with the black at the tip, and shading

 abdomen with four yellow uninterrupted belts. 



Buenos Aires. Parasitic on (Eceticus platensis, Berg. 



Not very closely allied to any other species known to me. 

 It somewhat resembles Conura in shape, and should perhaps 

 be referred to that genus.
