Exhibitio7is. 
Rare Ichneumon. —Mr. John J. Ward brought for exhi¬ 
bition an example of the ichneumon-fly, Rhyssa jJersuaso^'ia, $ , 
together with a photograph of the living insect. The speci¬

Beetle new’ to Science. — Mr. H. St. J. Donisthorpe ex¬

as Boarmia rhomboidaria had proved to be Odontopera bideii- 
tala. Further, that some of the moths had been bred from 
larvae fed exclusively on ivy, and though similar larvae had, as
