ICHNEUMON-FLIES — GELINAE : MESOSTENINI 375 



This species and T. ariagmus are the two Nearctic representatives 

 of a Holarctic species group which is characterized prunarily by the 

 crescentic elevation of the vertical carina on prepectus opposite lower 

 corner of pronotum and the wrinlded lower valve of ovipositor. 

 Secondary characteristics of the group are: General shape of head 

 and clypeus as illustrated in figures 399 and 400; long propodeum 

 with rather widely separated basal and apical carinae; rather evenly 

 curved apical carina of propodeum; nervulus about 0.38 its length 

 beyond basal vein; and nervellus broken usually above the middle. 

 Eurasian representatives of the group are T. glabricula (Thomson) 

 1873, and an undescribed species from Japan. These two are close 

 to the Nearctic T. cyperia and T. anagmus, respectively. One or 

 both of them may prove to be only subspeciiically distinct from the 

 Nearctic forms to which they are related. 



The species cyperia is distinguished by the median elevation of the 

 short vertical carina on prepectus that is opposite lower corner of 

 pronotum, segments 2-4 of hind tarsus yellowish, and tergite 4 partly 

 or entirely fuscous.
