FIELD NOTES. 
ICHNEUMONS. 
Ophion stigmaticus, etc., in Yorkshire. — It is advisable 
to correct a mistake which Professor Carr was unwittingly led 
into in his record of Yorkshire ichneumons on page 94 of The 
Naturalist for March last. Knowing that Agrotis agathina had 
never been recorded from Wakefield, I asked Mr. W. Fletcher 
from whence he had obtained the larvae which produced Ophion 
stigmaticus and Echphoropsis viennensis, to which he replied 
that they were from Skipwith Common near Selby. As Prof. 
Carr had received them from Wakefield (through Mr. J. W. 
Saunt), he naturally concluded they were from that district. —

MOLLUSCA. 
Pisidium henslowanum in Lines. S. — Recently I visited 
Bardney, Lines. I crossed the bridge and strolled down the 
south bank of the River Witham making a dip here and there 
for mollusca, which were apparently scarce. Among the few 
found were five specimens of Pisidium henslowanum. This 
is an important find as the only specimen recorded as P. 
henslowanum for S. Lines, in my ‘ Non-Marine Mollusca in 
Lincolnshire ’ (‘ L.N.U. Transactions,’ 1905) has since been 
identified, and recorded in his ‘ Cat. Brit. Species of Pisidium,’ 
B.M. (N.H.) 1913, by Mr. B. B. Woodward as Pisidium supinum 
and therefore makes this the only record of P. henslowanum 
for South Lincolnshire, Div. 13E. — C. S. Carter, Louth. Tune 
7th, 1914. 
NEUROPTERA AND TRICtlOPTERA. 
Lincolnshire Neuroptera and Trichoptera. — Some little 
time ago, Mr. F. W. Sowerby of Cleethorpes sent me for 
determination a few Lincolnshire Neuroptera and Trichoptera 
which may as well be placed on record. They were as follows : 
Ischnura elegans, Agrion puella, Panorpa germanica 
(Cuxwold). Raphidia xanthostigma (Roxton), Hemerohius 
quadrifasdatus (Cuxwold), Ckrysopa alba (Bradley), Gvammo- 
taulius atomarius (Bradley). Limnophilus flavicornis (Croxbv), 
L. vittatus (Croxby), L. affinis (Croxby and Grimsby), L. 
auricula (Roxton), L. lunatus (Croxby), Mystacides longicornis 
(Croxby), Silo pallipes (Freshery Bog), and Halesus radiatus 
(Cuxwold). 
Hemerohius inconspicuus can be added to the Lincolnshire 
list, Mr. Kenneth J. Morton having recently detected a speci- 
men among my series of H. elegans taken at Wells or Alford, so 
long ago as 1888, and sent to me by the late Mr. James Eardley 
Mason, along with H. elegans also from Lincolnshire. — Geo. T. 
Porritt, Huddersfield.
