REVIEW. 
Studies in North American Trichoptera, 1. 
By Lorus J. Milne, Cambridge, Mass., April, 1934; 19 pp., 
small 8vo. (For sale by author, 50c, postage extra; Biolog- 
ical Institute, Harvard Univ., Cambridge, Mass.). 
This includes keys to the North American genera and 
species of Phryganeidse, Molannidae and Leptoceridae, 
check-lists of world Phryganeidae and Molannidae and of 
North American Leptoceridae , in each case with only the 
North American synonomy. Three new genera, five new 
subgenera, three new species, four new subspecies and one 
new name are proposed; five old genera are resurrected, 
nine types of old genera are elected and thirty new North 
American synonyms are quoted, from a study of the type 
material in the Museum of Comparative Zoology, of Ha- 
gen’s and Banks’ names.
