Since this species was described in the ^Zoologist,' a fine 

 series of examples have been obtained from France ; it is the 

 M. pyrina of St. Fargeau; the sexes were captured at different

 them, and the probability of their being the same species was 

 suggested ; such proves to be the case. The species is very 

 common near Paris.
