REVIEW. 
Studies in North American Trichoptera, 1. 
By Lorus J. Milne, Cambridge, Mass., April, 1934; 19 pp., 
small 8 vo. (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 Molannidx and of 
North American Leptoceridve, 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.
