ocell-ocular line about two-thirds as long as ocellar diameter. 

 Propodeum with distinct longitudinal and apical carinae; areolet 

 much longer than wide; nervulus broken by the stump of a vein ; 

 nervellus broken slightly above middle. Abdomen rather stout, 

 weakly compressed at apex; postpetiole less than twice as long as 

 wide at apex. 



Ferruginous with ocellar spot black and trochanters and tarsi pale. 



Male. — More slender than female with postpetiole distinctly more 

 than twice as long as wide at apex; temples broader than eyes; 

 abdomen not at all compressed. 



Type-locality. — Hartford, Connecticut. 



Type.— C&t. No. 25982, U.S.N.M. 



One female from the type-locality June 24, 1904, and one male taken 

 by K. F. Chamberlain, June 15, 1919, at Durham, Connecticut. 



Tribe PANISCINI. 



As indicated above this tribe as here treated consists only of the 

 genera Paniscus Schrank and Parahates Foerster, and is most closely 

 related to the tribes Tryphonini and Cteniscini. 



The two genera are separable by the following key: 



KEY TO GENERA PANISCINI. 



Occiput margined; nervulus usually postf ureal; ovipositor strongly exserted. 



Paniscus. 



Occiput immargined; nervulus interstitial or nearly; ovipositor usually not strongly 



exserted Parabates. 



The characters employed in the above key are really all compara- 

 tive and the two genera are not more than subgenerically distinct. 

 Several authors have so treated them. But since the group as here 

 limited is so homogeneous this treatment is unnecessary and less 

 convenient than to consider them as genera. In certain species of 

 Paniscus the occipital carina is so faint as to be visible only from 

 certain positions; the nervulus is very variable in its position and 

 angle ; while the long ovipositor is not at all unusual in Parahates.

As indicated by the above synonymy Paniscus was first proposed 

 by Schrank; not by Gravenhorst, to whom it was for many years 

 credited. Schrank mentioned only one species in connection with 

 the genus, Ichneumon luteus, which he cited as an example. From 

 the context it is evident that Schrank intended Paniscus as a name
