680 Hymenoptera in America North of Mexico 



were reared from larvae of what is now called Synclilora aerta which had been sent by 

 T. A. E. Holcomb of South Pass, 111. I have not been able to determine that there is or 

 ever was a South Pass in 111., and the matter merits further research because the 

 syntypes of rufa were reared together with those of Aplodes rubivora Riley, presently 

 a synonym of Synclilora aerta.

Type-species: Zachrestoides euphydryadis Viereck. Orig. desig. 



This is a small Holarctic genus. The species B.fumigator Aubert and B. polonica Sawoniewicz 

 were rather recently described from Europe. The North American species which have been 

 reared parasitize Nymphalidae of the genera Euphydryas and Melitaea. I have seen material 

 that appears to represent three undescribed Nearctic species.

 before the appearance of this catalog.
