The following talile presents the arrangement of species adopted, 
together with a brief statement of jirincipal data, not repeated, 
for the most part, on later pages. Parentheses indicate records 
taken from the literature. This tabulation should lie useful in 
directing the attention of students to deficiencies in our know- 
ledge, and is intended to serve as a convenient form for recording 
new observations. Absence of remark in the last column means 
that only the macro pterous form is known.
