Linne under this species refers to one noticed by Ray ; 7 but Ray describes the 

 wings as " punctis nigris creberrimis pictce" words which evidently refer to B. 

 medius ; Mr. Samouelle, perhaps induced by this reference, has figured the latter 

 insect 8 as B. major. The reference in Syst. Nat. also to Geoffroy 9 appears to be 

 incorrect, for Linne describes the wing of this species not as basi fusca as GeofFroy 

 does ; but in these words " alee dimidium longitudinaliter fuscum." GeofFroy, as 

 well as Reaumur, 1 who is also quoted by more authors for this species, probably 

 had the B. minior in their eye, the wings of which Linne describes as " antice 

 versus basin obsolete fuscescentesy 2
