2 26 THE HYMENOPTERA ACULEATA OF DERBYSHIRE. 



B. pratorum, L. Burton, nest once found in manure heap 

 (E.B.) ; * Willington and Breadsall Moor occasionally 

 (G.P.) ; * Clifton and Dove Valley occasional (F.J.). 



B. terrestris, L. Very common and generally distributed. 

 Var. *virginalis, Kirb. 9 Breadsall Moor (G.P.). 



Apis mellifica, L. Occasionally reverts to a wild state. 

 Var. ligustica, Spin. " Lately . . . introduced at 

 Netherseal" (E.B., 1863). 



The above list contains altogether 105 species, but con- 

 firmatory evidence is very desirable in several cases, especially 

 in view of the fact that 19 species noted by Mr. Brown 

 have not been recorded in Derbyshire since 1863. Of these, 

 however, fourteen, at least, have been met with in adjacent 

 counties, and will most probably, sooner or later, be found 

 within our limits, while the rest remain doubtful pending 

 further evidence.
