it becoming gradually larger as it does so ; the apex 

 itself being broadly rounded. Antennae flattened and 

 dilated beyond the middle as in Joppa; mandibles at the 

 apex with two large teeth. Scutellum flat ; a broad, 

 curved, deep depression at its base ; its sides keeled. 

 Median segment without closed arese, only the posterior 

 median being defined, and it is open at the apex ; there 

 are no spines. Metathoracic spiracles linear, longish, 

 slightly curved, and placed near the base. Legs as in 

 Ichneitnion except as regards the metatarsus ; the claws 

 simple. Wings and gastrocoeli as Ichneumon. 



If it were not for the extraordinary structure of the 

 metatarsus this genus might be included in Ichneumon ; 

 but the hinder tarsi are shaped quite differently from 

 anything known among the Ichneumonidae. For anything 

 like its form we have to go to the saw-fly genus Croesus.
