and median segment form a combination of dis- 

 tinctive characters which warrants a new genus being 

 formed for this species, which I would name Xenopimpla. 

 The c^ is not described by Kirby. It agrees generally 

 in coloration with the ? ; but the scutellar keels, the 

 apex of the scutellum, the post-scutellum, the edges 

 of the apex of the mesonotum, and the metanotal spines 

 are yellow ; the furrow on the mesopleurae and the apex 

 of the mesopleurae, are black, but the extreme apex of 

 the latter is yellow ; the petiole is bordered with yellow, 

 the yellow band being narrowed in the middle ; the yellow 

 marks on the abdomen extend to the fifth segment ; one, 

 two, or three of the apical segments may be red ; the 

 hinder tibise may be for the greater part blackish and they 

 are less strongly spined. In both sexes the quantity of 

 black on the antennae varies, as does also the amount of 

 violaceous colour in the wings.
