This species, Promachus contradicens (including P. inter- 
ponens, from Australia), Promachus noninterponens, Ricardo, 
and Promachus raptor, Austen, form a group of nearly 
allied species, only distinguished by the colouring of the 
femora and by slight differences in the genitalia. They 
are large species, the females with broad bodies and very 
long ovipositors, both sexes with blackish abdomens and 
narrow yellow or golden-yellow segmentations. .
