 Order VI. NEUROPTERA.* 



(Ant-lh ^ion-flics, Caddiec-jlies, ct al^ 



The members of this or tier Jiare four icings ; these are membra- 

 nous, and usually furnished icit/i numerous i-cins. Tlie mouth-parts 

 formed for biting except in one family < Phry^aneidaj), ichcre (hey 

 udimcntary. The metamorphosis is complete. 



The term Neuroptera, or nerve-winced insects, is applied to the 

 members of this order on account of the numerous veins or nerves 

 with which the win<^s are strengthened. In this character ther 

 however, a close resemblance between the Neuroptera and the 

 idoneuroptera. Regard in< the relations of these two orders the 

 reader is referred to the remarks on pa^e 62. 



It is not certain that the Neuroptera as limited here is a natural 

 group. One family, the Caddicc-flics (Phrvgancid<c\ % differ- 



ttly from the other families that it has lonj been separated 

 distinct order; and more recently it lias been proposed for similar 

 to treat another family, the Scorpion-flies (l\inorpidu'}< in a 

 like manner. This multiplication of the orders has not yet been 

 rally accepted. 



inij to the ^reat variations in structure exhibited by the dif- 

 nt families, it is not easy to make ^enerali/ations re^ardini; this 

 order. I will, ther- erve the more di'tailed discussions of 



the structure of these insect^ for tin- special treatment of the indi- 

 vidual famil; 



The Neuroptera includes four families. These can be separ 

 by the following table:
