like to see this nomenclature question settled, to stay settled, will 

 find this paper most interesting reading. The subject is thor- 

 oughly discussed in all its aspects, and the author's suggestions 

 should be adopted. 



It seldom happens that the lover of out-doors is interested 

 in only one branch of natural history. The plant collector 

 usually has time for a glance at the birds and the bird student 

 is not insensible to the charms of the flowers. Both are naturallv 

 interested in the insects that cross their paths, and to such 

 as have not yet become familiar with their habits we would 

 recommend Hunter's '"Elementary Studies in Insect Life."* This 

 is not a guide to the various species, but rather an explanation 

 of the biological problems presented by this section of creatior 

 Our attention is engaged by such subjects as the life cycle, 

 special senses, protective devices, social life, instinct, relations of 

 plants and insects, wealth of insect life. etc. There are 258 il- 

 lustrations, a large number of them being photographs.
