Yorkshire Naturalists at Dent 
were not numerous, just a few being seen and one nest found. A Bull- 
finch was seen close to the village. Yellow Wagtails were observed on 
the roadside a little below Dent. A Whitethroat was seen by the river- 
side, many Willow Warblers were heard and a nest containing eggs was 
found. The Wood Warbler, Garden Warbler and Redstart were singing 
in Helmside Ghyll. Cuckoos were frequently heard, and one was seen 
perched on a tree, attended by a Tree-pipit which appeared to be trying 
to drive it off. Tawny Owls were calling at night, and one was seen 
during the daytime. The Common Sandpiper was frequently met with 
along the riverside, and a nest was found in a bank by the roadside, 
the bird flying off just as Mr. Mason’s car was passing. Many Curlews 
were seen on the hills, and two young were found on different areas of 
Rise Hill. Lapwings were seen, but not very many, and one or two 
pairs of Redshanks, a few Snipe were put up and a nest was found. A 
few pairs of Golden Plover occurred on Rise Hill. Corncrakes were 
calling in most of the fields in the valley, and Mr. Malins Smith had a 
good view of one. A Waterhen’s nest was found in a marshy field by 
the river. A Kestrel’s nest, containing young, was found on a ledge of 
rock. A brood of Grouse were found on Helms Knott. One or two 
Wood Pigeons’ nests were seen, and a young one was noticed perched 
on a tree in Helmside Ghyll. Partridges and pheasants were also 
seen. 
Several additions could probably be made to this list, but the majority 
of the Vertebrate Section had to leave before the reports were given at 
the meeting. 
Diptera (Chris. A. Cheetham) : — The following flies were mostly 
collected in the vicinity of the river or in Helmside Ghyll, some thirty 
odd of them have not been recorded previously from the North-west, 
V.C. 65. Perhaps the most interesting was a small Limnobid which 
was in plenty on the dry river bed where the stones were replaced by the 
solid limestone. It has only been caught once before in Yorkshire, 
near Coverham Abbey, and is known as Phabdomastrix schistacea Mg. 
Another nearly related species was Gonomyia tenella Mg. 
Another interesting species was Dicranomyia pilipennis Egg. Others 
of this genus were didyma Mg., mitis Mg., occidua Edw. Two other 
uncommon Limnobids are Epiphragma ocellaris L. and Ula macroptera 
Mcq. The others in this group being : — 
Dicranota subtilis, Lw. 
Tricyphona littoralis, Mg. 
Limnophila bicolor Mg. 
L. nemoralis Mg. 
L. ochracea Mg. 
L. lineola Mg. 
Dactylolabis frauenfeldi , Egg 
Molophilus murinus Mg. 
M. bifilatus Verr. 
M . appendiculatus Staeg. 
Ephelia marmorala Mg. 
There was one species of Ptychoptera, the rather rare paludosa Mg. 
and a single Pachyrrhina maculosa Mg., but the Tipulas were in 
plenty : — 
Tipula montium Egg. 
T . lateralis Mg. 
T. rufina Mg. 
T. unca Wied. 
T. variipennis Mg. 
T. cheethami Edw. 
T . scrip ta Mg. 
T. maxima Poda. 
Tipula fulvipennis Deg. 
T. oleracea L. 
T . v emails Mg. 
T. flavolineata Mg. 
T. luna Westf. 
T . variicornis Mg. 
T . alpium Bergr. 
T . subnodicornis Zett. 
Whilst in many of the dark spots on streamside and in the woods 
the phantom-like Dolichopeza silvicola Curt, was seen.
