The type of Luperodes is L. alboplagiatus Motschulsky from Ceylon, 
and the type of Monolepta is M. pauperata Erichson from Angola. 
Maulik, in treating these two groups in the Fauna of British India, 
states that he does not recognize the character of the coxal cavity as 
of generic value and unites them under the earlier name Monolepta. 
He does not make any attempt to study the genus as a whole. La- 
boissiére, in the Supplement to the Catalogus Coleopterorum, part 78 
(Galerucinae), believes ‘‘it is inadmissible” to separate the genus 
Luperodes and Monolepta on the character of the open or closed coxal 
cavities. Because I have not studied either of the two genotypes and 
because of the fact that they are so remote geographically from the 
American species, I hesitate to make any decision as to the generic 
position of the American species. At this time it seems wisest to 
leave these American species tentatively in the genus Luperodes under 
which they are listed in Leng’s catalog. Later the species will no 
doubt be assigned to several genera. I hope this study may awaken 
an interest in the group that will lead some one to make observations 
concerning the biology and food habits. These are almost unknown 
except in the case of L. brunneus (Crotch).
