to time so that the majority of their weaknesses should have been 

 eliminated. 



The work is comprehensive, yet detailed where detail is most needed, 

 and will at once meet a long felt want among students, teachers and 

 official entomologists. One cannot help but admire the boldness of the 

 author in his attempt to bring about order in a family where chaos has 

 so long reigned and particularly in his endeavor to develop a satisfac- 

 tory nomenclature. J. S. HOUSER. 



OBITUARY. 



Prof. Louis COMPTON MIALL, Emeritus Professor of Biology 

 in the University of Leeds, England, died on February 21, 

 1921. From an obituary notice in the Entomologist's Monthly 

 Magazine for April, 1921, we learn that he was born seventy- 

 eight years ago, son of a Congregational minister at Bradford, 

 attended Silcoates School, began teaching in a private school 

 in Bradford when fifteen, and became interested in natural his- 

 tory through his brother, a medical student. He had no sys- 

 tematic training in biology, but subsequently learned something 

 of its technique at the Leeds School of Medicine. He became 

 Secretary of the Bradford Philosophical Society at the age of 

 about 20, Curator of the Museum of the Leeds Philosophical 

 Society in 1871, first professor of biology in the Yorkshire Col- 

 lege of Science in 1876, and later in the University of Leeds 

 until he retired in 1907. He was elected a fellow of the Royal 

 Society in 1892, of the Entomological Society of London in 

 1894 and a Special Life Fellow of the latter in 1916. 



While his earlier researches were in vertebrate paleontology 

 and morphology, he soon became interested in the anatomy, 

 physiology and development of insects, publishing :
