We give the diagnosis of each family in terms of the venation as in 
Hampson; but it is not possible, unless one already knows the venation 
well, to simply use this diagnosis; to the systematist familiar with the terms 
used, the diagnosis is useful for reference ; to the general student nothing 
but careful study with the Fauna and Catalogue of Lepidoptera 
Phalsenae will make this diagnosis of any use and we refer the worker who 
wishes to identify specimens to these volumes. For this reason also 
we give no explanation of the venation or terms, since the whole art of 
using them depends on a knowledge of the interpretation put on them by 
systematists, which is quite different from that of ordinary people.
