The Rev. T. A. Marshall (Trans. Ent. Soc. Lond. 1889, 

 ])t. ii. June, p. 184) says : — " The Rev. A. E. Eaton brought 

 a specimen [of /. reunitor^ Nees] from Spitzbergen " — re- 

 ferring probably to the present species. 



Ichneutes spp. are known to destroy saw-fly larvae (Tenthre- 

 dinidse), and Holmgren remarks (/. e.) that /. hyperhoreus 

 doubtless parasitizes JVemafus (i. e., Fristiphora) frigidus, 

 Bohem. The latter species was also secured by the expe- 

 dition \_cf, Morice, Ann. & Mag. Nat. Hist. ser. 9, vol. x.

 genus have now been bred from maggots in carrion.

This is probably a parasite of some small ncniatocerous 

 dipteron.
