ADDITIONS TO EPICAUTA, WITH NEW 
SYNONYMY AND A CHANGE OF NAMES 
(COLEOPTERA: MELOHLE) 1 
By F. G. Werner 
Biological Laboratories, Harvard University 
The numerous specimens of Epicauta which have been 
made available to the author in the past two years have 
included several new species from the United States and 
Lower California as well as specimens which indicate that 
some of the former conclusions regarding our species 
were erroneous. The most important changes are in- 
cluded in this paper. The author owes a debt of gratitude 
to the curators of almost all the major museums in North 
America for their generosity and especially to Mr. Frank 
H. Parker and Mr. G. P. Mackenzie, who have been most 
free with specimens from their private collections and 
with information of real value in understanding the limits 
of some of our species. 
The arrangement followed is that of my former paper 
on the genus, and changes that will have to be made in the 
key to species and in descriptions will be noted in their 
proper places under the species concerned.
