BRITISH DRAGONFLIES OF THE OLDER ENGLISH 



AUTHORS. 



By W. J. Lucas, B.A., F.E.S. 



(Continued from p. 260.) 



7. W. F. Evans: 'British Libellulince,' 1845. 



Under this title we have a small book containing twenty-one 

 plates, in which are figured fifty-two dragonflies, a brief notice 

 of each being given in twenty-eight pages of letterpress. The 

 author believes " that one good figure of an insect is better 

 than the most elaborate description by itself." Acting on this 

 belief, he states that he has drawn the plates with the greatest 

 care from the insects themselves. In this, however, he has 

 achieved but a very moderate degree of success, for the drawing 

 of the figures is extremely poor, and the colouring worse. It is, 

 in fact, with the greatest difficulty that several of the insects can 

 be recognized at all, and the identification therefore of some of 

 the figures is given with considerable diffidence. The first two 

 plates are devoted to details and nymphs.
