SOME NEW WEST INDIAN EUMOLPID BEETLES 
By Doris H. Blake 
This paper is made up of the descriptions of six new 
species of Metachroma and a new species of Chalcosicya. 
Four of the seven new species were collected by Fernando 
de Zayas, who has been actively collecting insects in Cuba 
over many years. One of the other species was taken by Dr. 
J. F. G. Clarke on the Breden Smithsonian expedition in 
1956 and the two others are from miscellaneous material 
in the National Museum collection.
