under the head of the orders in 



which they have been most commonly placed; in each case, how-

There is one more pi '. mollification of the Linn;ean -\ >tem 



which should be noticed in this phu irly all of the families in 



the Ofd ;doneuroptera and Neuroi)tera are remarkably dis- 



i family differs from the other families in the same Ol 

 in much more important characters than usually distinguish families 

 in the other order-. At the same time the characters which distin- 

 h either of these orders are not well marked. For ti 



r Brauer holds that the Pscudoneuroptera and the Neurop- 

 not natural orders, but that the former group includes I 

 and the latter three distinct ord

bet of the Termitidai, Psocichu. and Mallophaga as an order, the 



Corrodentia) I cannot follow Professor Brauer, I am inclined to think 



that in the main the school of entomologists which he represents is in 



the rigl: irds the number and characters of the orders of the

 the old classification I have been greatly influenced by a desir

 belief that an elementary text-book should follow rather than

 the facts in such a manner as to clearly indicate the ideas of 



iifferent schools. 

 On the following page two lists of orders are given. In the first

 column are indicated the various other orders that ha
