THE CHRYSOMELID BEETLES LUPERODES BIVITTATUS 
(LECONTE) AND VARICORNIS (LECONTE) AND SOME 
ALLIED SPECIES 
By Doris H. BLakE 
Most of the vittaie and yellow-brown species of Luperodes Mot- 
schulsky from the United States are at present listed under the 
names L. bivittatus (LeConte) and L. varicornis (LeConte), respectively. 
There are at least five vittate species, all very similar in markings, 
confused with biwittatus, and I have found 11 of the yellow-brown 
species that in one collection or another have been labeled varicornis. 
Both vittate and yellow-brown species are small and inconspicuous 
and not particularly noteworthy, with the exception of JL. 
brunneus (Crotch), which Horn synonymized with varicornis. L. 
brunneus is a well-known pest throughout the South on corn and 
cotton. 
There is considerable question whether some of the species should 
not be removed from the genus Luperodes. They have certain char- 
acteristics in common with the species of that genus having black or 
metallic coloration, but in general are not closely related. Schaeffer 
has described one species, actually synonymous with varicornis 
(LeConte), as belonging to the genus Monolepta, mainly because of its 
closed anterior coxal cavities. Some of the others discussed here 
have closed anterior coxa! cavities and are related to species from 
Mexico and Central America described by Jacoby and also assigned 
to the genus Monolepia.
