 NOTES ON SYNONYMY.

In this paper will be found descriptions of two genera and 12 

 species of Ichneumonoidea and Chalcidoidea. Notes on synonymy 

 of some species already described are also included. All of the new 

 species are described from reared material and the descriptions are 

 published at this time in order to make the names available for use 

 in economic papers dealing with the host insects. 



Superfamily ICHNEUMONOIDEA. 



Family ICHNEUMONIDAE. 



Subfamily JoPPlNAE. 



PHAEOGENES (CENTETERUS) INEPTIFRONS, new spedcs. 



This species runs in Foerster's synopsis of the Ichneumonidae, 

 satisfactorily to the genus Centetervs except that the head is more 

 transverse than quadrate, though with the posterior orbits full and 

 nearly as broad as the transverse diameter of the eyes. The female 

 is easily separated from any other Phaeogenines known to me by the 

 transverse carina on the f rons. 



Female. — Length 6.5 mm. Slender; head thorax and abdomen 

 some what shining, finely and nearly uniformly sculptured, the meso- 

 pleura and mesosternum with some distinct punctures, most nu- 

 merous on the mesosternum. Occiput deeply concave; antennae 

 short, 20-jointed, thickened slightly toward the apex, the basal joint 

 of the flagellum a little shorter than the second joint, second and 

 third flagellar joints subequal, and about two and one-half times as 

 long as thick, following joints shorter, the apical one conical, about 

 twice as long as thick, the penultimate joint quadrate; clypeus 

 sculptured like the face, with a few irregularly placed punctures, its 

 anterior margin nearly straight; a line from the antennal fossae to
