44 Yorkshire Naturalists’ Union : Annual Report , 1921. 
nemorale Bl., being new to V.C. 64, and another, Panamomops bicuspis 
Gamb., scarce in the county. Examples of Dysdera crocota C. L. Koch, 
a ‘ Mediterranean ’ species, have turned up at Selby (W. N. Cheesman 
and J. F. Musham), at Scarborough (D. W. Bevan), and near Hudders- 
field, the last (with its egg sac) from a bunch of Canary bananas. Mr. 
Bevan later sent a female Pisaura mirabilis Clerck (taken at Langdale), 
a spider of Holarctic distribution and usually plentiful, but in Yorkshire 
as in some other districts, unaccountably rare. The cave dweller, Meta 
menardi Latr., is reported as being present in Kirkdale Cave (V.C. 62) by 
Prof: Watson ; two male Evarcha falcata Bl., not a common or widely 
distributed spider in the county, were taken in Defter Wood, Cawthorne ; 
Epeira patagiata C. L. Koch, Hillhousia misera F.O.P.Cb., and the water 
spider still remain on Skipwith Common. The ‘ Spiders of Yorkshire ’ 
“has run serially through The Naturalist, and will shortly be concluded. 
Satisfactory progress continues to be made in the investigation of the 
mite fauna. Several species have been added to the county list, one 
being new to science, Liodinychus winteri Hull, collected by W. P. 
Winter, at Shipley, 1919, and described in The Vasculum, February, 
1921, and another new to Britain, Histiostoma muscarum Schrnk., found 
on a fly at Farnley, Leeds, by C. A. Cheetham. The total of the gall- 
mites has been sensibly increased, some of the additions being recorded 
in the accounts of the ‘ Plant Gall Forays at Leeds,’ in The Naturalist for 
August and November. 
Early in the year F. A. Mason submitted at different times two living 
false scorpions, both from Leeds — Cherries godfreyi Kew from diseased 
Begonia roots, which had been sent to him from Cardiff, and C. dubius 
Camb. from under birch roots in Roundhay Park, two very closely 
allied species. The former has not occurred in Yorkshire, and of the 
latter only 5 examples have so far been met with, in V.C. 61, 63 and 64. 
Plant Galls (Wm. Falconer) : — The members of the Union 
interested in plant galls met twice during the year to work a selected 
area in the vicinity of Leeds, and the species obtained have been listed 
in the August and December issues Of The Naturalist. Records for other 
districts — Scarborough, York, Selby and Huddersfield — await publica- 
tion, one of them being for the dipteron Lipara lucens Mgn., a local 
species apparently new to the North of England, which, by the shortening 
of the internodes, causes a ‘ cigar ’ shaped gall on the stems of Phragmites 
communis Trin. Breeding out various gall agents tends to shew the 
inadvisability of taking anything for granted. The nodal swelling of 
the twigs of the birch has always been thought to be due to the moth, 
Epiblema tetraquetrana Haw., but an example of this kind taken from 
Honley Old Wood, near Huddersfield, produced Chrysoclista aurifrontella 
Hb., quite an unexpected and previously unknown yield. In the same 
wood on the same bushes there are sometimes slight but distinct lateral 
swellings of the internodes, each tenanted by a yellow, tinged with red 
(especially at extremities), dipterous larva, which seems to have escaped 
the attention of naturalists, at least as a gall agent. Again, in British 
:gall -books, the ‘ cigar ’ shaped gall of the couch grass is assigned to one 
■or other of the diptera. Chlorops taeniopus Mgn., or Lonchaea parvicornis 
Mgn., but in the Huddersfield district, the result of four years’ breeding 
out from various localities, the emerging insects have, without exception, 
been a hymenopteron , probably the Chalcid Isosoma graminicola Gir. 
which affects Agropyrum s'pp. on the Continent. 
Messrs. Bagnall and Harrison, in The Naturalist for October, under 
the comprehensive title of ‘ The Midge Galls of Yorkshire,’ published a 
list of the species which have come under their notice, most of the records, 
however, having reference to V.C. 62, a comparatively restricted area. 
Other districts supply fourteen additional species, the names of which 
may be gleaned from the pages of the above journal 1918-1921, while the 
following, amongst others, have not hitherto been recorded for the 
Naturalist
