PREFACE 
For several years a number of unidentified species of the sub- 
family Pyraustinae have been accumulating in the Barnes Collection. 
Recently on a visit to the British Museum we took specimens of these 
species with us in the hopes of getting them identified; in some few 
instances we were successful and several of these names proved to be 
new to our faunal region; in the majority of cases however we failed 
to find any names applicable and venture in the following paper to 
describe these species as new. We are fairly certain at all events that 
they have never been described previously from N. American material, 
as only some half dozen of the species at present listed in Dyar’s cata- 
logue are unknown to us and the descriptions of these do not appear 
to fit any of our material. Of course there is always the possibility 
that some of our species will prove identical with Mexican or West 
Indian species, but we have no doubt that those better placed than we 
are to study such material will find no difficulty in correcting any 
errors into which we have fallen on this score. 
We preface our descriptions with a list of species which should 
be added to our present list.
