348 PHYTOPHAGA.—SUPPLEMENT. 
This species agrees with the type of the genus, UZ. fulvicollis from Guatemala, in 
the strongly developed frontal tubercles and the robust and gradually tapering antenne, 
in connection with the punctate-striate elytra and closed coxal cavities; the thorax, 
however, is much more transverse and the elytral epipleure are broader. The female 
has the antenne much thinner, the third and fourth joints being slender and elongate, 
and the lateral interstices of the elytra costate. The elytra in both sexes have a slight 
metallic zeneous lustre. Numerous specimens of both sexes. .

Just as we are closing this volume Dr. Horn has called my attention to the fact that 
my name érevicollis is preoccupied by Leconte; I therefore propose to change it as 
above.
