EECENT LITERATURE. 



The Biology of Dragonflies (Cambridge Biological Series). By R. J. 

 TiLLYARD. (Cambridge University Press, 1917. 15s. net.) 



Some twenty-five years ago there did not exist in English a 

 reliable textbook on the dragonfly. No modern one was to be found 

 in our language at all, and the late Baron de Selys Longchamps in 

 Belgium was almost their only champion. Of the "neglected orders," 

 in fact, the Odonata did seem, indeed, neglected. Yet for their size, 

 their beauty of shape and colour, their powers of flight, and their 

 peculiarities biologically, they stand out pre-eminent amongst the 

 Insecta. Now, however, there is a great change in this respect. 

 Their students, indeed, may not be as numerous as they might, but 

 there is no question about the value of the work which has been, 

 and is being, done to raise the dragonflies from the obscurity into 

 which they had undeservedly fallen. The work done, however, has 

 been extremely scattered in numberless papers in many languages.
