September. INFo-st of these ep-gs batch out early in the following spring, as they 

 are usually found in the wheat plants in March and April. A few may, 

 however, hatch out the .«anie autunni, as on November 23rd, 1917, I found 

 two third-stage larvae attacking wheat plants on the University Farm. On 

 February 13th, 1920, I found a second-stage larva attacking wheat on the 

 University Farm. 



The lar\ a on hatching from the e'^g makes its way into the middle of a wheat 

 shoot, where it feeds at tji.e base of the shoot, which it kills. Wlien fully fed 

 the third-stage larvae make their way into the soil, where they pupate about 

 one-and-a-lialf to two inches below the surface. Pupation usiually takes place 

 in May. — I'. K*. PETiiKuBitiixiK, ^NI.A., School of Agriculture, Cambridge:

Louis Coni/)t(>n Miull. — On February 2Ist, 1921, occurred the death of 

 Dr. L. C. Miall, F.R.S., Emeritus Professor of Biology in the University 

 of Leeds, aged 78. The son of a Conju'egational Minister at Bradford, he was 

 educated at Silcnates School, but left at the age of L5 to take up a teaching 

 post in a private school at Bradford. He became interested in natural history 

 through contact with his brother, who was a medical student; but he had na 

 systematic training in biology, though he afterwards attended the Leeds School 

 of Medicine in order to learn something of biological technique. He became 

 Secretary to tlie Bradford Philosophical Society at the age of about 20. In 

 1871 he was appointed Curator of the Museum of the Leeds Philosophical 

 Society, and in 1876 became the first Professor of Biology in the Yoikshire 

 College of Science, continuing in that office in the University of Leeds till 

 1907. He then retired to Letchwortli, but returned to the North after the 

 death of his wife in 1918. 



Miall's work covered a very wide field, and he gained a leading position- 

 through his studies as a biologist, bis excellent st}le as a writer, and his talents^ 

 as a lecturer. His earlier work was palaeontological, and through it he came' 

 into contact with Huxley, to whose influence he attributed much. His- 

 subsequent zoological work was largely concerned with insects,, and as an' 

 entomologist he is probably best known by his " Natural History of Aquatic 

 Insects," ])ublished in 1895, and reprinted with additions in 1903 and again ini 

 1912; and by his three monographs on the structure and life-history of,, 

 respectively, the cockroach (written in conjunction with Prof. A. Denny, 1886) ;. 

 the harlequin fly, Chironomtis (done in collaboration with A. R. Hammond,. 

 1900) ; and the Tipulid fly Phulacrocera replicata (in collaboration with 

 R. Shelf ord, Tr. Ent. Soc.Lond. 1897). He was intensely keen on what he termed; 

 " live natural history," as was evinced not only in parts of the writings 

 mentioned above, but also in his books " Round the Year" and " House, Garden,, 

 and Field," and in his Presidential Address to the Zoological Section of the 

 British Association at Toronto in 1897, on " Life-history studies of animals " 

 (reprinted in Ann. Rep. Smithsonian Inst, for 1897). He also had strongs 

 views on methods of teaching, and wrote books on " Object Lessons from 

 Nature" and "Thirty Years of Teaching." Nor was the historical side of
