Superfamily ICHNEUMONOIDEA 445 



segnis segnis (Provancher). Que., Maine, N. H. N. Y., n.w. S. C, Mich. Ecology: I have seen a 

 long series of males collected in Malaise traps placed in the crowns of Abies 

 balsa)tiifera. Host: Profenusa canadensis (Marl.).

 subguttata (Gravenhorst). Europe. Introduced in N. B., Que., and Ont. in 1937 and 1938, 



apparently without becoming established. Host: Gilpinia hercyniae (Htg.). The host 

 listed was the target species for the introductions in North America, although a small 

 number of individuals was released in an infestation of Neodiprion lecontei (Fitch). 

 Although the number of individuals released against G. hercyniae at some places was 

 large (as many as 6108 males and 10974 females) A. subguttata has not been found in 

 North America since 1939 when it was recovered from G. hercyniae in Parke Reserve, 

 Kamouraska Co., Que.

Type-species: Oxytaenia rufolineata Cameron. By subsequent monotypy from 

 inclusion by Cameron, 1904. 



Townes (1970) said that he saw 13 species, all of which are Neotropic except for the fact that 

 one of them has a Nearctic subspecies.

Townes and Townes (1962) placed this small Holarctic genus in the Cryptini (=Mesostenini), 

 subtribe Echthrina along with four other genera, but only Echtbrus was transferred to the 

 present tribe by Townes (1970).
