 Occurrence of the true Migratory Locust in Lincolnshire. 



— On Friday last Mr. H. Wallis Kew sent me a living female of Pachytylits migra- 

 torias L. to identify, and has asked me to send a notice of its occurrence. He 

 obtained it from a taxidermist in Louth, to whom it was brought by a little girl, 

 who said it was found in a stubble field at Withern, eight miles from Louth. — 

 Eland Shaw, St. Mary's Hospital, London, W., 19th October, 1886. 



[In presence of the fact that the Yorkshire specimens of 1876 were referred 

 by Mr. Robert McLachlan, F.R.S., and the Baron de Selys-Longchamps, to 

 Pachytylits cinerascens, the occurrence of the true P. migratoritis is of considerable 

 interest. Mr. Shaw informs me that not only the specimen now recorded, but the 

 other British examples he has seen, were referable to the true migratoriits, which 

 is very readily distinguishable from cinerascais. He expresses a wish to be placed 

 in communication with any entomologists of the North of England who collect 

 Orthoptera, inasmuch as all the localities from which he at present possesses 

 specimens are in the South. Entomologists who possess Northern specimens of 

 Orthoptera cannot, therefore, do better than increase our very limited range of in- 

 formation on this department of the entomological fauna of the North, by entrusting 

 their specimens to him for determination. — W.D.R.]

Messrs. Taylor and Francis will shortly publish a work by Mr. T. Mellard 

 Reade, F.G.S., entitled 'The Origin of Mountain Ranges.' In addition to con- 

 taining a systematic theory of Mountain-Building, with detailed Experimental 

 Illustrations, the Structure and Geological History of the great Mountain-Masses 

 of the Globe will be discussed. The work will also contain many Maps and 

 vSections of Mountain Ranges, and a contoured Map of the North-Atlantic Ocean, 

 together with numerous sketches of Mountain-Structure and Scenery, from Nature, 

 by the Author. . >co< 



Geological readers will be glad to know that the celebrated Clayton fossil tree 

 has found a permanent home in one of our northern universities, Prof. Williamson, 

 F.R. S., having purchased it for Owens College, Manchester. The genial and 

 learned professor was in Clayton recently, and, along with the curator of the 

 college, personally superintended the removal, which, by the help of Messrs. 

 Murgatroyd and their workmen, was very expeditiously and carefully done, being 

 accomplished in three days. The weight of the fossil, when detached from its 

 bed, was found to be about five tons, certainly a respectable weight for a single 

 specimen of our Yorkshire carboniferous vegetation.

In Section C (Geology) of the British Association at the recent meeting in 

 Birmingham, were read a large number of papers bearing in some way upon the 

 geology of the North of England, viz.: — Report on the Erratic Blocks of England 

 and Wales, Dr. Crosskey, F.G.S. ; Notes on the discovery of a large Fossil Tree 

 in the Lower Coal Measures, at Clayton, near Bradford, S. A. Adamson, F.G.S.; 

 Report on the Fossil Plants of the Tertiary and Secondary Beds of the United 

 Kingdom, J. S. Gardner, F.G.S. ; On recent researches amongst the Car- 

 boniferous Plants of Halifax, Prof. W. C. Williamson, F.R. S. ; On the Lower 

 Palaeozoic Rocks near Settle, J. E. Marr, F.G.S.; On the exploration of Raygill 

 Fissure, J. W. Davis, F.G.S.; On Concretions, H. B. Stocks; On the Strati- 

 graphical Position of the Salt Measures of South Durham, Prof. Lebour, F.G.S.; 

 On the Classification of the Carboniferous Limestone series, Northumbrian type,

At the October meeting of the Entomological Society of London, Mr. W. F. 

 Kirby exhibited, on behalf of Mr. John Thorpe, of Middleton, a long series of buff 

 and melanic varieties of Avipliidasis betularia, and read notes on them com- 

 municated by Mr. Thorpe. The Rev. W. W. Fowler exhibited a number of 

 minute Acari, which had been doing injury to fruit trees near Lincoln. Mr. 

 Poulton gave an account of experiments recently made by him with the larvae of 

 several species of Vanessa, for the purpose of ascertaining the relations of pupal 

 colour to that of the surface on which the larval skin was thrown off, and exhibited 

 the frame constructed for these experiments. Naturalist,
