FURTHER NOTES ON NORTH AMERICAN 
EPICAUTA, WITH NEW SYNONYMY 
(COLEOP., MELOIDAE) 
By F. G. Werner 
Department of Zoology, University of Vermont 
The availability of series of several of our species of 
Ejjicauta has made possible a more thorough study of the 
species involved than has been possible before. Some of 
the more extensive necessary changes are recorded in this 
paper. Several of the series have been sent for determina- 
tion and are acknowledged under the species. Most of the 
1 ‘esl were collected by Dr. and Mrs. W. L. Nutting and the 
author during the summers of 1948^ and 1949.

A long series of this species (over 150 specimens) was 
collected by the author 15 miles west of Lordsburg, New 
Mexico, Aug. 30, 1949, on fiowers of a grass. Most of 
the specimens fit the description of calcarata. Some have 
broader and some have narrower tibial spurs than the holo- 
type of that species. Two abnormally small individuals (7 
mm.) have sparser pubescence and more slender legs and 
tibia! spurs. The color of the pubescence varies from ciner- 
eous to dull yellow-cinereous, being cinereous in most. 
Two paratypes of emarginata Champ., kindly loaned by 
Mr. J. Balfour-Browne of the British Museum, agree per- 
fectly with some specimens in the Lordsburg series, and 
differ from the holotype of calcarata only in having slightly 
more slender posterior tibial spurs. The shape and size 
’ This trip, for the purpose of collecting and studying Anthicidae, was
