 unnecessarily difficult by the arrangement and nomenclature he has 

 adopted. The work is a very valuable addition to our local lists and 

 should be in every library. It is clearly and well printed, and very 

 free from errors, though an important one occurs on the last page, 4th 

 line from bottom, when " micro " should be " macro." 



THE MIGRATION OF INSECTS.

 Mr. Sharp's articles in the numbers of the Young Naturalist for 

 May and October last year, appear to take us back into the misty 

 reminiscences of what entomology must have appeared to our fore- 

 fathers some fifty years ago. From his two articles, I take it, he de-
