Hosts: This species is a parasite of microlepidopterous larvae that 

 live in concealed or protected situations. The type and a number of 

 paratypes were reared in the Ottawa region from Paraclemensia 

 acerifoliella (Clemens). Other records include rearings from Amorbia 

 humerosana (Clemens), Choristoneura fumiferana (Clemens), Coleo- 

 phora pruniella Clemens, C. salmani Heinrich, Chrysopora stipella var. 

 naeviferella (Duponchel), Gracillaria sp., holster case on Vaccinium, 

 larva in hawthorn fruit, Phalonia rutilana (Hiibner), pistol case on 

 apple, and Spilonota ocellana (Denis and Schiff ermiiller) . 



This species has a transcontinental distribution and is found mostly 

 in the Canadian and Transition zones. 



Erythroscambus Walley, new subgenus 



Type: Pimpla hirticauda Provancher. 



Submetapleural carina usually absent (rarely a very weak carina is 

 present in hirticauda); mesoscutum in most regions usually bare or 

 with only very sparse hairs, occasionally with moderately dense hairs; 

 propodeum with dorsomedial carinae absent or represented only by 

 weak longitudinal elevations separated by a shallow median sulcus; 

 subgenital plate in female with a large, basal, membranous excision; 

 ovipositor rather weakly compressed, with ridges on apex of lower
