88 A New British Lichen, etc. 



Grit, proving, if such proof were needed, that the sands and- 

 associated gravels of glacial origin in Airedale are made up 

 of locally derived material. 



In view of the mineralogical work upon the clastic deposits 

 now being carried on in various parts of the British Isles, it 

 has been thought advisable to publish this record. 



A NEW BRITISH LICHEN. 



Rev. W. JOHNSOX. 



I found the lichen here diagnosed, in Teesdale, Durham, that 

 favourite hunting-ground of the late W. Mudd. I classed it 

 as follows : — 



Lecanora privigna Nyl., var. flava Johns. — Thallus effuse, 

 thinnish, more or less continuous, leproso-tartareous, rarely 

 smoother or rimulose, yellow-grey K-C- ; apothecia moderate, 

 innate at first with distinct thalline margin, then lecideine, de- 

 pressed in the centre and occasionally convex, dark-brown or 

 black, more or less circumcissed and white pruinose ; para- 

 physes discrete, except at the brown apices ; spores numerous, 

 minute, oblong ; hymenial gelatine bluish, then intensely yellow- 

 wine-red with iodine. 



This lichen grows on the limestone, and was found in 

 an old limestone-quarry, on the opposite side of the road to 

 the Church, near Langdon Beck. I purpose including it in 

 the 13th Fasciculus of ' The North of England Lichen- 

 Herbarium,' which I hope to issue shortly. 



Miss A. L. Smith, F.L.S., of the British Museum, Natural 

 History Department, has classed this lichen as a new species, 

 under the name Biatorella flava A.L.S., Syn. Lee. privigna 

 Nyl., var. flava Johns, in the new Monograph on British Lichens. 



Cumberland Hemiptera. — A study of last autumn's 

 captures has enabled me to add two more species and a variety 

 to our county list. Phytocoris dimidiatus Kb., a single specimen, 

 was beaten from Oak at Orton in September. In the same 

 month, I beat several specimens of Psallns alnicola D. and S.. 

 from Alder near Dalston. By sweeping in a grass}- lane near 

 Kirkbampton, I captured a specimen of Calocoris ochromelas 

 var. fornicatus D. and S. This is a very distinct variety, 

 and in confirming my determination, Mr. E. A. Butler, B.A., 

 F.E.S., says it is apparently a northern form, the original 

 specimens having come from Durham. It is not included in 

 Mr. Whittaker's Lancashire List, and it would be of interest 

 to know if Yorkshire collectors have met with it. — Jas.
