36 HANDBOOK OF ANTS, BEES, ETC. 



The Trichoptera are also placed by some entomologists in a 

 distinct order, on account of the peculiarity in their wings being 

 clothed with hairs. They, however, present so many points both 

 in habits and structure, analogous with the true Neuroptera^ that 

 we have retained them as a sub-division of the Order.
