The species of this genus are probably the most elegant, as regards coloration and 

 shape, among the Ichneumonidse. Yellow or lemon-yellow is the predominating 

 ground-colour, the head, thorax, and, more rarely, the abdomen being marked with 

 black; the wings are yellowish or hyaline, marked with black, or, more rarely, 

 entirely black. They are (except a few species from India, South Africa, and 

 Australia) natives of the Neotropical region. It is very difficult to point out any 

 characters whereby the species, as a whole, may be distinguished from Ichneumon, and 

 especially from Trogus.
