io THE SCOTTISH NATURALIST 



"Bonhill" occurs before ('01) in the list, the locality was 

 included in the last mentioned ; where it occurs otherwise 

 the species has only been taken since 1901. The initials in 

 the list refer to the following collectors : R.H. = R. Henderson ; 

 A.F. = Anderson Fergusson ; A.A.D. = A. A. Dalglish ; J.J.K. 

 = J. J. F. X. King ; J.R.M. = J. R. Malloch ; G.W.O. = G.W.Ord. 

 The arrangement of the species is according* to Morice's papers 

 in the Entomologist's Monthly Magazine (" Help-Notes towards 

 the Determination of British Tenthredinidae, etc."), which is 

 based upon Konow's Tenthredinidae Eur opa. The significance 

 of the occurrence of the sexes is so slight that, except in 

 certain cases, I omit mention of them. 



LYDINI. 



Lyda stellata, Chr. Cadder Wilderness, T. Grant ('01); Bonhill, 

 J.R.M. Colintraive, J.J.K. Cameron records a species as 

 Lyda nemoralis, L., in 1876 and 1878, for Paisley Moss, as 

 sometimes common. Nemoralis, L., is not British, and 

 stellata being absent from Cameron's lists, I suspect his 

 species is the above. 

 Pamphitius balteafits, Fall. New Galloway ('86) Bonhill, J.R.M.

CEPHINI. 



Macrocephus satyrus, Pz. Bonhill, J.R.M. 



Cephus pallipes, Kl. Cambuslang, A.A.D. ('01); Bonhill, J.R.M. 



SIRICINI. 



Strex gigas, L. This introduced species, which has occurred for 

 a considerable period in the area, may now be considered 

 as a resident species in Bute and Argyll. 

 ,, juvencus, Fab. Has occurred in various parts of the area, 

 but so far as I know has no claim to rank as a resident 

 species. Noctilio, Fab., may also occur, and may have 

 been recorded bsjuvencus.
