YORKSHIRE NATURALISTS AT BOLTON WOODS 
(Continued from page 270). 
CoNCHOLOGY.—Mr. W. Denison Roebuck, M.Sc., writes :— 
The Conchological Section was represented by its President, 
Mr. Greevz Fysher, Mr. J. W. Taylor and myself. About 27 
species had been observed, two water shells, eight slugs, and 
the rest land shells. The principal addition to the known 
fauna of the area was Zonitoides excavatus, found in numbers 
on an old stump in the Laund Pasture Plantation, above 
the Valley of Desolation, in company with Hyalinia fulva. 
Limnea peregra was also added to the known list. Among 
the rarer species taken were Hygvromia fusca, Zomitoides nitidus, 
Hyalinza helvetica, etc. 
CoLEOPTERA.—Dr. Fordham writes :—The present writer 
spent the day in Posforth Gill and the Valley of Desolation 
and on the left bank of the Wharfe in Bolton Woods in com- 
pany with Messrs. Falconer and Winter, (to whom he is in- 
debted for several of the species recorded). 
Beetles were not as numerous as expected, although a few 
species, e.g., Abax ater Vill., Otiorhynchus picipes F. and 
Strophosomus coryli F. were rather abundant in the woods. 
Fifty-three species were obtained altogether, including two 
specimens of Malthodes brevicollis Pk. (nigellus Kies) by sweeping 
near the Wharfe, which has not previously been found in 
Yorkshire. 
Mr. Falconer obtained Paramecosoma melanocephalum Hbst. 
by sweeping near the river and Mr. Winter captured a Tiger 
Beetle (Cicindela campestris L.) in the Valley of Desolation. 
Three species of Bembidium, ustulatum L. (=littorale Brit. 
Cat.) decorum Pz., and tibiale Duft, were abundant in shingle 
by the River Wharfe and by the stream in Posforth Gill, and 
in the latter place occurred in company with Bembidium 
atroceruleum Steph., Stenus guttula Mull. and mnitidiusculus 
Steph. and Helodes marginata F. In the pine wood Rhagium 
bifasciatum F. and its larve occurred in a fir stump and a 
specimen of R. mordax De G. (inquisitor Brit. Cat.) was 
swept up in the same locality. Other beetles obtained by 
‘sweeping in the woods were Anthobium primule Steph. (from 
Primroses), Phyllobius oblongus L. (commonly), P. viridicollis 
F., Barynotus merens F. (from Mercurialis perennis), Sciaphilus 
aspervatus Bonsd. and Orchestes fagi L. Other beetles worthy 
of passing mention are Tetraplatypus similis Dj., Bembidium 
mannerheimt Sahl., Anacena globulus Pk., Tachinus humeralis 
-Gr., and collaris Gr., and an entirely black specimen of Elmis 
aeneus Miill., (the latter taken in wet moss by the waterfall 
in the Valley of Desolation). 
In addition to these species the following beetles were taken 
11916 Sept. 1.
