﻿VIII INTRODUCTION 



Names preoccupied or cited in error we have marked 

 with an $, 



Finally we have thought it advisable to include a full 

 index of all the species as well as the genera in order that 

 the numerous shiftings which have been necessary should 

 give no trouble to the average collector in locating any 

 given species. 



A few additions and corrections will be found at the 

 end of the list proper. 



Decatur, Febry., 1917.
